RELATED APPLICATIONS 
   The present application is related to commonly invented, commonly assigned application Ser. No. 09/611,087, entitled SOFTWARE REMOTE DOWNLOAD METHOD FOR AUTOMATIC RETRIEVAL OF ROYALTY AND WARRANTY INFORMATION, which is hereby incorporated by reference. 

   FIELD OF THE INVENTION 
   The present invention relates to updating software in remote locations through the use of an intermediary, a system for tracking what locations have what versions of the software, and a method of assembling a database related to that information. 
   BACKGROUND OF THE INVENTION 
   Fueling environments have become more sophisticated in recent years and now include complex software to operate fuel dispensers, site controllers, and a myriad of other devices within the fueling environment. The physical hardware of these devices is routinely upgraded as new features become available. Not only do the devices within the fueling environment continue to be upgraded, but also the software is periodically upgraded as new features or elements are added to the functionality. New software may include merely new features, a new operating system, an upgraded version of an operating system, or the like. 
   For basic fueling sites, there are typically three components having microprocessor controllers and software associated therewith. The primary computer of the fueling site is generally referred to as the site controller. Each fuel dispenser may also include one or preferably two microprocessors. The first microprocessor controls the core functions of the fuel dispenser such as the opening and closing of valves, meter readings, and the like. The second microprocessor controls the display functions, the printer for receipts, and other functions. These are known as CRIND™ functions by the assignee of the present invention. Some fuel dispensers integrate these two microprocessors into one, but the functions remain the same. Software is used to enable these microprocessors with all the desired functionality. The site controller may communicate with and/or control one or both of the microprocessors in the fuel dispenser depending on the installation. 
   Presently, companies that supply fuel dispensers and other fueling environment hardware are forced to rely on Authorized Service Contractors (ASCs) to perform upgrades and warranty related service. The company provides the ASC with a floppy disk having the new software version thereon. Upon a request from the fueling environment, an ASC must then personally visit the requesting fueling site and upload the software through the site controller. If the fuel dispenser software is being upgraded, the site controller must download the software to the fuel dispensers at the instruction of the ASC. Furthermore, when the fueling site is responsible for requesting software upgrades, the end result may be a patch work upgrade wherein different versions of software may exist on different fuel dispensers and the site controller. Thus, when the ASC visits the fueling environment to upload a newly requested version of the software to the site controller, the ASC may inadvertently install an upgrade that is incompatible with the existing software on the fuel dispensers, or create other incompatibilities within the system. 
   Some fuel dispensers store the software for the core functions on EEPROMs rather than other read/write capable memory. Thus, the ASC must manually replace the EEPROMs to perform a software upgrade for the core functions. Assignee of the present invention has recently introduced two fuel dispensers, ECLIPSE™ and ENCORE™ that replace the EEPROMs with FLASH memory. However, for existing fuel dispensers that use EEPROMs, there is great potential for error, as the EEPROMs for the upgrade may have been illegally copied by the ASC and there may be errors in the copied versions. Likewise, if they are improperly installed, additional errors may be generated. Finally, the EEPROMs may not be compatible with the software operating the site controller or the CRIND microprocessors. 
   Although this system has worked for many years, the pace with which technological advances in the fueling industry are made is accelerating. This acceleration spurs ever more frequent upgrades to the software in the fueling industry. Thus, any problems associated with the system will rapidly become exacerbated. 
   The present system has other failings in terms of how accounting is performed for the transaction associated with these upgrades. The first transaction is that between the company selling the upgrades and the fueling site purchasing the upgrades. The selling company must have an accurate count of exactly what was provided to the particular fueling site and how many copies were provided so that the fueling site may be billed accordingly. The second transaction lies between the ASC and the company selling the upgrade. The ASC is typically paid for each installation of a program that he or she performs. Thus, again, the selling company must have an accurate count of exactly what was provided to the particular fueling site and how many copies were provided so that the ASC may receive his appropriate commission. In the past, the ASC was responsible for keeping paper records of the work performed. While helpful, such documents are susceptible to fraud, human error, easy loss, or destruction. Additionally, there may be a transaction between the selling company and a third party software vendor. The selling company may owe royalties to the third party software vendor based on the upgrades provided. Thus, an accurate count of the upgrades must be kept so that the royalty payments are kept current. 
   In short, there remains a need for an improved method by which software upgrades may be distributed to remote fueling sites from the company responsible for the hardware at the fueling site. 
   SUMMARY OF THE INVENTION 
   The present invention replaces the floppy disks of the prior art with a portable computing device such as a laptop computer adapted to receive software upgrades from a corporate controlled computer. The portable computing device is issued to the Authorized Service Contractors (ASCs). Upon a request from a fueling site, the ASC is dispatched to the fueling site and links the portable computing device to the site controller to perform the upgrade. The portable computing device includes additional software adapted to sense the number and type of hardware devices available at the fueling site as well as the current version of the software presently installed on each of those devices. The portable computing device then determines if the requested upgrade is compatible with the present hardware and software configuration as well as storing a record of the present hardware and software configuration. If compatible, the software is upgraded as requested, and the record is updated as well. The number and versions of the upgrades installed are appended to the record, eliminating the need for the ASC to keep a paper record of the work performed. Additionally, the ASC may enter a record of any service or maintenance performed at the fueling site, either in conjunction with the software upgrade or as an independent act. This maintenance or service may be required as part of a warranty obligation on the part of the selling corporation, as part of a previously purchased service plan, or as an isolated service call as needed or desired. 
   Periodically, the ASC accesses the corporate controlled computer and uploads thereto information relating to the upgrades and services that the ASC has performed since the last access. From this information, the corporate entity may arrange for billing to the fueling sites that have purchased upgrades as well as provide commissions to the ASC for the work performed. This may also facilitate payment of royalties to any third party software provider. The upload also includes information about what fueling sites have what hardware and what version of software installed thereon. This is preferably assembled into a database from which recommendations may be made as to what upgrades a particular fueling site should investigate purchasing. Other departments within the corporation may also use the information within this database as needed or desired. 
   As an added feature of the present invention, the portable computing device may include or have access to intermediate upgrade options or patches to facilitate software upgrades. For example, if the present hardware and software configuration is incapable of accepting the requested upgrade, after identification of this fact, the portable computing device may be able to provide a best alternative solution or provide a required intermediate upgrade prior to providing the requested upgrade. Thus, if the original device were running software v. 1 and the site had requested software v. 3, the portable computing device could upload software v. 2 and then install software v. 3 onto the device. If no such intermediate upgrade is required, then it is not performed. If a known patch exists which enables a particular piece of hardware to function with the requested upgrade, it could similarly be provdided. If no such intermediate upgrade or patch is possible, then no upgrade is performed. Additionally, if the intermediate upgrade or patch is not available, but is feasible, then the portable computing device should have the ability to access the corporate controlled computer remotely and download the intermediate upgrade for uploading to the fueling site. 
   As a further option, the ASC may use the portable computing device to log in to the corporate computer from the remote site and receive instructions on what updates are needed at a particular site. This information may be provided based on reported configurations. Further, the order in which the updates must be installed may be passed to the ASC at that time. If the updates are not available on the portable computing device, the ASC may download them at that time.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The present invention is directed to a method for improving upgrades to software in a fueling environment. However, a discussion of the physical elements comprising a fuel dispensing environment will be helpful as a background. Turning now to  FIG. 1 , a fuel dispenser  10  is adapted to deliver a fuel, such as gasoline or diesel fuel to a vehicle  12  through a delivery hose  14 , and more particularly through a nozzle  16  and spout  18 . The vehicle  12  includes a fill neck  20  and a tank  22 , which accepts the fuel and provides it through appropriate fluid connections to the engine (not shown) of the vehicle  12 . A display  13  provides a user interface from which the user can determine a cost associated with a particular fueling transaction. While display  13  is preferably a visual display, it may equivalently be an audio user interface, such as might be used by the visually impaired or the like. 
   Flexible delivery hose  14  is a flexible member  30  that includes the product delivery line  36  and the vapor return line  34 . Both lines  34  and  36  are fluidly connected to an underground storage tank (UST)  40  through the fuel dispenser  10 . UST  40  may be vented by a vent line  46  capped by a vent valve  48  as is well understood in the art. Once in the fuel dispenser  10 , the liens  34  and  36  separate at split  51 . Note that split  51  need not be precisely where indicated, it only need be positioned within the housing of the fuel dispenser  10 . Pump  42 , controlled by motor  44  extracts fuel from the UST  40  and provides it to product delivery line  36 . This can be done by creating a vacuum in line  36  or other equivalent means. 
   A vapor recovery system is typically present in the fuel dispenser  10 . During delivery of fuel into the vehicle fuel tank  22 , the incoming fuel displaces air containing fuel vapors. Vapor is recovered from the vehicle fuel tank  22  through the vapor return line  34  with the assistance of a vapor pump (not shown). A motor (also not shown) powers the vapor pump. A control system  50  receives information from a meter and a pulser in the fuel delivery line  36 . Meter measures the fuel being dispensed while the pulser generates a pulse per count of the meter. Typical pulsers generate one thousand (1000) pulses per gallon of fuel dispensed. Control system  50  controls a drive pulse source that in turn controls the motor. The vapor recovery pump may be a variable speed pump or a constant speed pump with or without a controlled valve (not shown) as is well known in the art. 
   Control system  50  may be a microprocessor with an associated memory or the like and also operates to control the vast majority of the various functions of the fuel dispenser  10  including, but not limited to: those functions discussed above, fuel transaction authorization, encryption associated with fuel transaction authorization, fuel grade selection, display and/or audio control. As noted, control system  50  may actually comprise two microprocessors that may communicate with one another. Recent advances in the technology associated with the fuel dispenser  10  now enable the fuel dispenser  10  to act as an Internet interface, provide content, allow music downloads, or other functionality. Resident in the memory associated with the control system  50  is software that facilitates all of these functions. As a result of these increasing numbers of functions, the software resident in the memory associated with the control system  50  must periodically be upgraded to support new functions or improvements on existing functions. 
   In addition to fuel dispenser  10 , other devices may exist within a fueling site  100  that likewise may require electronic control systems and software to enable those electronic control systems as better understood with reference to FIG.  2 . Fueling site  100  may include a primary building  102 , a plurality of fueling islands  104 , a car wash  106 , and other outbuildings as needed or desired. Primary building  102  may include a convenience store  110 , a quick serve restaurant  112 , a back room  114 , and other subdivisions as needed or desired. It should be appreciated that the fueling site  100  is preferably an integrated fueling site that enables purchases of a multitude of goods and services at a multitude of locations, such as that discloses in U.S. Pat. No. 6,098,879, which is hereby incorporated by reference. 
   A site controller  150  for controlling this fully integrated fueling site may be positioned in back room  114 , or other location within the fueling site  100  as needed or desired. Site controller  150  is preferably a computer, such as the G-SITE® sold by assignee of the present invention. Site controller  150  is communicatively linked to fuel dispensers  10 , a station attendant terminal  152  positioned within the convenience store  110 , an external customer terminal  154 , an external quick serve restaurant order terminal  156 , an internal quick serve restaurant terminal  158 , an external sensor  160 , a car wash terminal  162 , and other electronically controlled terminals positioned throughout the fueling site  100 . Quick serve restaurant  112  may include an auxiliary order pick up terminal  158 A that is proximate an order pick up window  164 . These terminals and sensors facilitate the fully integrated nature of the fueling site  100 . 
   Additionally, the site controller  150  may control vapor control systems such as the vent valve  48 , a site wide vapor recovery pump, or other such devices that may exist within fueling site  100 . This may be part of a comprehensive vapor management plan designed to comply with the ever more restrictive CARB requirements or other government regulations. Such vapor management systems may have their own microprocessors and memory, or may be integrated into the site controller  150  as needed or desired. However, every change in the regulations may result in a change in the software or hardware and software to comply with the new regulation. 
   Site controller  150  may also have access to remote content providers  166  such as through the Internet, a dedicated phone line or the like. In the preferred embodiment, this is a high speed, large bandwidth connection allowing for fast transfers of large amounts of data. 
   Reference is again made to the previously incorporated &#39;879 patent for a full description of the myriad terminals and stations within the fueling site  100 . That patent also provides a nice description of the potential functions that many of the terminals and stations may perform. 
   Turning now to  FIG. 3 , the system of the present invention is disclosed. Corporation  200  supplies the hardware and software to the fueling sites  100  as is well understood. Examples of such a corporation include Marconi Commerce Systems, Tokheim, Wayne, and the like. While a corporate entity is contemplated, it should be appreciated that for the purposes of the present invention, an S corporation, a partnership, a sole proprietorship, or other legal entity is also intended to be within the confines of the term “corporation.” Corporation  200  may include a corporate computer  202 . Corporate computer  202  may include a single server, a multitude of servers being interconnected through a local area network (LAN) or a wide area network (WAN), may include an external portal to the Internet, or may be a closed system that is only accessible by physically porting into the computer  202  or other conventional computing arrangements as are well understood. In the preferred embodiment, corporate computer  202  hosts a web page that acts as a portal to data stored within memory associated with the computer  202 . It should be appreciated that the web page may include publicly accessible portions as well as proprietary portions that are only accessible through a firewall or other security measure. 
   An Authorized Service Contractor (ASC)  204  may be in possession of a portable computing device  206  such as a laptop computer sold by IBM. Particularly excluded from the definition of a portable computing device is a memory unit without any processing power such as a simple floppy disk. While not preferred, other portable computing devices are contemplated such as a cellular phone, personal digital assistant, or the like. Portable computing device  206  may communicate with the corporate computer  202  by means of a wire based or wireless connection as is well understood in the art. This may be accomplished with a DSL modem, a cable modem, a wireless modem, or other modem as needed or desired as well as the appropriate software to control such as modem. Alternatively, the portable computing device  206  may be selectively networked with the corporate computer  202  such over a LAN having dedicated ports for such a connection. Other well known communicative connections are also contemplated. 
   Further, the portable computing device  206  is adapted to communicate with the site controllers  150  at the fueling sites  100 . Again, this communication may be over any conventional communication means, wired or wireless, networked or dial in access as needed or desired. 
   Armed with this knowledge of the elements, a description of the methodology of the present invention may be better understood. In particular, to provide for the coherent and productive upgrading of software within fueling sites  100  based on upgrades made available from the corporation  200 , reference is made to  FIGS. 4-6 . Beginning with  FIG. 4 , an ASC  204  acquires a portable computing device  206  (block  300 ) and accesses the corporate computer  202  (block  302 ). This access, as previously noted, may be wireless or wire based and may be accomplished through any number of conventional computer to computer communication techniques. Additionally, note that it may be preferred that the portable computing device  206  access the corporate computer  202  through a web page. Again, access to the web page may be done directly through direct communication with the corporate computer  202 , or it may be done via the Internet as is well known. Portable computing device  206 , subsequent to access, may download new versions of software from the corporate computer  202  (block  304 ). Portable computing device  206  stores this software in a memory unit (block  306 ). This may be done on a hard drive, in flash memory, in an auxiliary memory unit such as a read/write CD, a zip drive, or the like as needed or desired. However, preferably, the software is stored on the hard drive associated with the portable computing device  206 . 
   Corporate computer  202  may reset any counters within the portable computing device  206  (block  308 ). These counters correspond to any work (i.e., remote software upgrades) already performed by the portable computing device  206 . Specifically, the portable computing device  206  should indicate that no versions of software have been uploaded and need to be accounted for by the corporate computer  202 . Alternatively, and equivalently, the corporate computer  202  may provide a time stamp to the portable computing device  206  such that all work prior to the time stamp is effectively ignored or purged from memory. This is to prevent an ASC  204  from being credited for work previously performed and for which there has already been an accounting. Other ways to perform this function may be readily apparent to those of ordinary skill in the art. The techniques listed herein are exemplary and not intended to be limiting. 
   Corporate computer  202  provides any auxiliary instructions (block  310 ) to the portable computing device  206 . These auxiliary instructions may include a conflict checking instruction that identifies earlier software versions with which the present version is incompatible. Likewise, hardware that will not support the present software version may be identified. Further, solutions to known conflicts that have been developed, typically known as “patches” in the computer industry may also be provided. Patches as used herein also includes workarounds and supplying intermediate upgrades so that the latest version of a software package is adequately supported. Other auxiliary instructions may also be included if needed or desired. 
   Finally, the portable computing device  206  is disengaged from its communicative link with the corporate computer  202  (block  312 ). Note that the precise order of the download need not identically follow that set out in FIG.  4 . For example, the auxiliary instructions could be downloaded prior to the download of the new software package. 
   Additionally, note that there may be a verification step wherein the corporate computer  202  verifies the identity of the portable computing device  206 . This may be done by password protection, a particular encryption authorization process, or the like as needed or desired. This will reduce the likelihood of industrial secret theft by unauthorized access to the new software. The particular verification process is not material to the present invention. Likewise, the portable computing device  206  may verify the identity of the corporate computer  202  before accepting a software download. 
   Armed with the new software stored on the portable computing device  206 , the ASC  204  then travels personally to a fueling site  100  that has requested a software upgrade or other service. ASC  204  is alerted to the request of the fueling site  100  by conventional techniques as are already used in the industry. For example, an electronic message may be sent to the ASC  204  if desired. The use of wireless communication technology such as cellular phones and pagers may also facilitate the expedient transfer of information from the corporation  200  taking an order for a software upgrade to the ASC  204 . Reference is now made to  FIG. 5  that shows in a flow chart the steps that the ASC  204  takes upon arrival at the fueling site  100  that has requested a software upgrade or other service. 
   In particular, the ASC  204  uses the portable computing device  206  to access the site controller  150  (block  350 ). This, as noted above, may be through any conventional wire based or wireless communications technique. Portable computing device  206  then polls the hardware within the fueling site  100  for the current configuration of hardware (block  352 ). This will report how many peripheral terminals, sensors, and other devices are located at the fueling site  100 . Typical information includes indicia relating to devices such as a car wash terminal  162 , how many dispensers  10 , drive through external sensor  160 , the vapor management system, and the like. Furthermore, the polling will also determine what software, including version number, is presently operating on each of these peripheral devices and the site controller  150  (block  354 ). 
   The present discussion operates under the assumption that the fueling site  100  has requested an upgrade. However, this need not be the case. Upgrades could be provided automatically as part of an existing service contract, as part of a warranty, or other contractual relationship as needed or desired. In any event, the portable computing device  206  may access the corporate computer  202  after polling to determine what upgrades are needed or possible. Such remote access is discussed in greater detail below. If the portable computing device  206  does not have the upgrade resident in its own memory, it may download the upgrade as needed. 
   Portable computing device  206  may then determine whether or not the requested software upgrade is compatible with the presently existing hardware and software at the fueling site  100  (block  356 ). If the answer is no, the current software and hardware will not support an upgrade to the requested software, then the portable computing device  206  determines if the problem can be fixed by providing a patch (block  358 ). This may be done by accessing the corporate computer  202  and receiving instructions on what patches are available and in what order they must be installed. Other techniques are also contemplated. Thus, if it is known that the particular upgrade is incompatible with a previous version of software installed in hardware deployed at fueling sites, but that this problem may be fixed through the installation of an intermediate version of the software prior to the installation of the requested version, then the problem may be deemed fixable. If the answer to block  358  is yes, the problem is fixable, then the appropriate patch is uploaded to the site controller  150  (block  360 ). Note that this patch upload may involve the portable computing device  206  contacting the corporate computer  202  from the fueling site  100  to download the patch, if the patch is not in the memory device of the portable computing device  206 . This remote access may be accomplished by a phone line, a wireless connection, or through the fueling site&#39;s access to remote content providers  166  previously discussed. 
   If the problem cannot be fixed, then an error message may be generated (block  362 ) and the process continues to block  370  (block  364 ). Once the patch has been installed, then the portable computing device  206  uploads the requested software to the site controller  150  (block  366 ). Software so uploaded is transferred from the site controller  150  to the peripheral devices if appropriate (block  368 ). Note that the patch may be installed after the requested software in some instances if needed or desired. 
   Portable computing device  206  then records any warranty service performed by the ASC  204  at the fueling site  100  (block  370 ). This may include any maintenance, repairs, or other service that warranties on the hardware including the fuel dispenser  10  present at the fueling site  100  may require. Further, the portable computing device  206  records any software upgrades that have been delivered (block  372 ) including any patches delivered. This may include an indication of the previously existing version of the software prior to the upgrade. The ability to distinguish between what was in place and what was installed may have an impact on the royalty due any third party software vendor. Still further, the portable computing device  206  records all the current hardware and software at the fueling site  100  along with identifying information (block  374 ) such as the physical street address, the client number, or the like so that the information about the hardware, software, the upgrades, and service may be appropriately attributed to the correct fueling site  100 . Finally, the portable computing device  206  is disengaged from the site controller  150  and the ASC continues about his merry way (block  376 ). 
   It should be appreciated that security concerns may dictate that the identity of the site controller  150  be verified prior to any data transfer and that the site controller  150  may verify the identity of the portable computing device  206  prior to acceptance of any software revisions. This may be accomplished by any known technique such as an encrypted verification code, a password, or the like as needed or desired. 
   Note that the portable computing device  206  could access the peripheral devices of the fueling site  100 , namely the fuel dispenser  10  and other peripherals, directly and provide software upgrades thereto. However, this is not preferred, because it requires additional security measures at each peripheral device and does not take advantage of the fact that the site controller  150  already communicates with the peripheral devices and thus requires only one access point. 
   Having completed all the visits to different fueling sites  100  that are required, the ASC  204  should periodically use the portable computing device  206  to access the corporate computer  202  (block  400 ) as noted in FIG.  6 . This subsequent access may be accomplished in the same manner that the first access was accomplished, and is preferably through a web page. This access may in particular be done remotely if needed or desired. Again, note that appropriate security measures are taken to prevent fraudulent access to the corporate computer  202  and the portable computing device  206 . Portable computing device  206  uploads to the corporate computer  202  a record of all services that have been rendered to the disparate fueling sites  100  since the last time the portable computing device  206  accessed the corporate computer  202  (block  402 ). Portable computing device  206  may then upload records of the software installed since the last access (block  404 ). This includes a number of each version of software that was installed. For example, six copies of version seven were installed. Finally, the portable computing device  206  uploads the records of fueling sites&#39; present configurations (block  406 ). Implicit in all of these uploads are identifying information that links the particular service performed to a location at which the service was performed, the particular software installed to a location at which the software was installed, and the location at which a particular configuration of software and hardware may exist. Further, indicia representing the ASC  204  that performed the work is also included. Note that both sessions wherein the portable computing device  206  communicates with the corporate computer  202  may be dictated in part by JAVA applets that control the portable computing device  206  during connection to the corporate computer  202 . 
   Corporate computer  202  may then bill the fueling sites  100  accordingly for the services and software provided (block  408 ). Note that the fueling sites  100  may already have paid for the services and software as part of a service contract, or as part of the original warranty. In either case, the corporate computer  202  may make an entry on the invoice that the service was performed or the software was delivered. Corporate computer  202  may then account for any commissions that are due the ASC  204  as a result of the services provided and the software installed (block  410 ). This may include calculating a commission rate, calculation of number of jobs performed, charging against an invoice, or any other required accounting procedure. Payment may be made to the ASC  204  in any conventional fashion such as printing a check, direct deposit, or the like. 
   Corporate computer  202  may then account for any royalties due third party software vendors (block  412 ) that may result from software upgrades performed by the ASC  204 . This may include creating an invoice, making a charge against a payment received from a fueling site  1100 , or any other accounting procedure as is well understood in the art. 
   Corporate computer  202  may also update a database containing information about the customers&#39; present hardware and software configurations (block  414 ). Specifically, the corporate computer  202  may link a location identifier with the configurations and from the configuration make recommendations on potentially desirable upgrades that may be available to a particular fueling te  100  based on what is presently installed at that location. 
   Finally, the corporate computer  202  should reset counters within the portable computing device  206  to reflect that the ASC  204  has been credited for all work performed since the last access to the corporate computer  202  (block  416 ). This may also be accomplished with a timestamp function as previously described. 
   Please note that the order of steps presented above is not necessarily an absolute. Alternative, equivalent orders are also contemplated and within the scope of the present invention. 
   Additional functions may also be performed in the corporation  200  with the information uploaded from the portable computing device  206  to the corporate computer  202 . In particular, a service department of the corporation  200  may access the records to make sure that fueling sites  100  are getting the service for which they have contracted, or that they need to stay competitive. Additionally, a warranty department could access to records to make similar inquiries, but related more specifically to service and upgrades that are required as part of a warranty contract. Further, a marketing department could access the information to determine which fueling sites  100  should receive mailings notifying them of newly available upgrades, service options, or the like that may be helpful to the fueling site  100 . While the term “department” has been used, the term is used herein to include occasions where there is not a corporate structure, or personnel who perform these functions are not necessarily organized in a discrete department. The term is meant to be construed broadly. 
   Additionally, a personnel department may use the information provided to evaluate an efficiency associated with a particular ASC. This may be determined by comparisons to other ASCs, other empirical evidence, or other criteria as needed or desired. Further, an inquiry as to the quality of the service may be generated and sent to the fueling site  100  that received the service. This may help customer relations if feedback generated as a result of the inquiry is acted upon. 
   Still further, the costs associated with the services and upgrades may be evaluated by personnel in marketing to determine warranty pricing based on the number of upgrades that are being performed. Additionally, the costs associated with upgrades and services may be matched against research and development costs to determine if pricing associated with the products corresponds to the costs associated with creating those products. Other database mining may be accomplished as needed or desired. The present examples are not intended to be limiting. 
   The present invention may, of course, be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changed coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
