BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates generally to electronic commerce. In particular, the present invention relates to technology that facilitates data interchange between disparate application systems via a communications network. 
   2. Background Information 
   Advances in communications technologies have allowed businesses to exchange data electronically for decades in what is now commonly referred to as electronic commerce. There have been a number of approaches to defining standards for data exchange in electronic commerce applications. One of the earliest approaches to standardization is Electronic Data Interchange (EDI). EDI refers to transactions that are exchanged between known trading partners using mutually agreed upon data security, formatting, and transmission standards, such as those developed by the American National Standards Institute (ANSI) Accredited Standards Committee (ASC) X12 in 1989. An international standard, the Electronic Data Interchange for Administration, Commerce, and Transport (EDIFACT), was developed under the auspices of the United Nations and later adopted by ISO in September, 1987. The Federal Acquisition Computer Network (FACNET) is an example of an EDI system authorized by the Federal Acquisition Streamlining Act of 1994, 10 USC §2304(g), and is used to exchange acquisition information between the federal government and private-sector vendors. 
   Despite its success, the use of EDI to support today&#39;s electronic commerce applications has its limitations. EDI transactions use a highly structured and inflexible data format. Since most companies run proprietary business application systems that either do not or cannot use this same standard format for their internal data, both the initiating and receiving companies must each translate the structured data formats into their own internal data formats. Since internal data formats are often modified to accommodate changing business requirements, keeping the translation software up-to-date is not a trivial task. 
   Another limitation is that the data interchange cannot be performed in real-time. Rather, the EDI transaction must be electronically transported from one computer enterprise to another where the data is then translated or re-entered into a receiving application system before use. However, today&#39;s cross-enterprise computer systems often require that the data from the initiating company feed directly into the application system of the recipient company. This presents a problem in that the content and format of the EDI transactions are unlikely to be 100% compatible between the initiator and the recipient. 
   As an example, state of the art Enterprise Requirements Planning (ERP) systems such as the SAP system are very adept at driving uniform transactions within a company. However, the SAP system is much less adept at communication to external ERP systems. Compatibility issues can occur even when two companies use the same SAP system because it is very likely that the two SAP systems are configured differently. Hence, manual data mapping and translation may be required. 
   Information technology groups are struggling with data mapping and translation issues. First, business processes to handle transactions with data mapping issues are often poorly defined. Also, many application systems lack mechanisms to resolve data mapping issues once the transaction reaches their domain, or those mechanisms if they do exist are inadequate (e.g., by failing to transmit a clear error report to the initiator). What is needed, therefore, is a new approach to allow companies to develop intelligent electronic interfaces that comprehend the data mapping and translation requirements between disparate application systems.

   DETAILED DESCRIPTION OF THE INVENTION 
   In the following description various aspects of the present invention, a method and apparatus facilitates data interchange between disparate application systems via a communications network will be described. Specific details will be set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced with only some or all of the described aspects of the present invention, and with or without some or all of the specific details. In some instances, well-known features may be omitted or simplified in order not to obscure the present invention. 
   Parts of the description will be presented using terminology commonly employed by those skilled in the art to convey the substance of their work to others skilled in the art, including terms of operations performed by a computer system or electronic commerce application, and their operands, such as transmitting, receiving, retrieving, determining, generating, protocol, data structure, and the like. As well understood by those skilled in the art, these operands take the form of electrical, magnetic, or optical signals, and the operations involve storing, transferring, combining, and otherwise manipulating the signals through electrical, magnetic or optical components of a system. The term system includes general purpose as well as special purpose arrangements of these components that are standalone, adjunct or embedded. 
   Various operations will be described as multiple discrete steps performed in turn in a manner that is most helpful in understanding the present invention. However, the order of description should not be construed as to imply that these operations are necessarily performed in the order they are presented, or even order dependent. Lastly, repeated usage of the phrase “in one embodiment” does not necessarily refer to the same embodiment, although it may. 
   With reference to  FIG. 1 , an overview of the present invention is illustrated in the context of an operating environment in accordance with one embodiment. As shown, a method and apparatus is provided in which a initiator system  140  exchanges data with a recipient system  160  over the Internet  120  or other communications network through the use of an e-commerce appliance  110  and a data mapping database  130 . In one embodiment, each of the initiator  140  and recipient  160  systems are typically comprised of an application software  152 / 172  such as an ERP system, and associated application database  154 / 174 . An Internet transaction server  150 / 170  provides the access to applications that are external to the corporate enterprise (i.e. outside the corporate firewall) via the Internet. Specifically, the Internet transaction server  150 / 170  provides Internet services that allow the initiator application software  152  to interface with the recipient application software  172  (and vice versa) as well as to other external systems over the Internet  120 . The Internet transaction server  150 / 170  operates in conjunction with: a web server  148 / 168  and web client  146 / 166  which together provide a user interface to the external applications, the switches and/or routers  144 / 164  which control access to the external applications, and a telephone or other type of communication system  142 / 162  which provides for remotely transmitting and receiving data to and from the external applications. 
   In one embodiment, the e-commerce appliance  110  is either directly or indirectly coupled to the switches and routers  144 / 164 . Among other things, the e-commerce appliance  110  operates to intercept outgoing data prior to being transmitted to the recipient application software  172  from the initiator application software  152 , or to intercept incoming data prior to being received by the recipient application software  172 , or some combination thereof. In one embodiment, the e-commerce appliance  110  is implemented in both the initiator  140  and recipient  160  systems, although it may be implemented on one and not the other, or be enabled on one and disabled on the other. When disabled, the data will simply bypass the e-commerce appliance  110  and continue to its destination recipient application software  172  via the switches and routers  164 , etc. of the recipient system  160 . The e-commerce appliance  110  operates in conjunction with the data mapping database  130 , which is accessible to both the initiator  140  and recipient  160  systems via the Internet  120  or some other communications network. In operation, the e-commerce appliance  110  interfaces directly to the communications systems (i.e. the switches and routers  144 / 164 , etc.) that control access to the Internet services for the initiator  140  or recipient  160  systems respectively. 
   It is readily apparent from these examples that the connections to the Internet or communication network  120  may be a wired or a wireless communication connection. In the case of a wired connection, the communication connection may be a serial or a parallel link, a serial bus, as well as a “harsh environment” local area network segment provided using any one of a number of communication medium known in the art, including but not limited to the Public Switching Telephone Network (PSTN), the Integrated Service Digital Network (ISDN), a Frame Relay network, an Asynchronous Transfer Mode (ATM) network, or the Internet, depending on the requirements of the initiator  140 , the recipient  160 , and the data mapping database  130  being accessed. In the case of a wireless connection, the communication link may be any wireless network controller designed in accordance with IEEE 802.11 Wireless LAN Standard or a wireless transceiver designed in accordance with the Draft Specification of Bluetooth: A Global Specification for Wireless Connectivity, promulgated by the Bluetooth Special Interest Group. Accordingly, connections to the communication network  120  will not be further described. 
   With reference to  FIG. 2 , one embodiment of the e-commerce appliance  110  is illustrated in further detail. In the illustrated embodiment, the e-commerce appliance  110  is comprised of a transaction tracker  112  logic capable of tracking data between the initiator  140  and recipient  160  systems in order to classify the data as data for which data mapping is fully functional, or as data for which data mapping is still in a debug phase. In one embodiment the tracked data is a communications message that represents a transaction to the application software  152 / 172 . If the data mapping is fully functional, then the transaction is further processed by a data mapper  116  logic that maps the data from the transaction format and content issued by the initiator system  140  into the transaction format and content that is capable of being received by the recipient system  160 . However, if the data mapping is still in the debug phase then the transaction is further processed by a data debugger  114  logic capable of identifying which data have unresolved data mapping issues. Both the data mapper  116  and the data debugger  114  logic use data mapping requirements posted on the data mapping database  130  as necessary to perform the proper data mapping or to identify whether and which data mapping issues are present. When data mapping issues are present, the data debugger  114  logic reviews the transaction data format requirements of both the initiator system  140  and the recipient system  160 . In this way, discrepancies in the transactions can be identified and potentially repaired before being routed to the application software  172  in the recipient system  160 . 
   Referring now to  FIG. 3 , a flow diagram of the operation of the e-commerce appliance  110  is illustrated in accordance with one embodiment of the present invention. As shown in process block  310  the operation of the e-commerce appliance  110  begins with intercepting the transaction transmitted from the initiator switch/router  144 . In one embodiment, the interception can be performed on the initiator system  140  before the transaction is transmitted to the recipient system  160 . In an alternate embodiment, the interception may be performed upon receipt in the recipient system  160  but before the transaction can be routed to the recipient application software  172 . It should be understood that the transaction may be intercepted at other points in the process without departing from the principles of the invention as long as the interception occurs before the transaction is processed by the recipient application system  172 . 
   At process block  320 , the intercepted transaction is identified with reference to the corresponding data mapping requirements posted on the data mapping database  130 . Specifically, if the data mapping for the intercepted transaction is determined to be fully functional, then the operation of the e-commerce appliance  110  continues at process block  360 , in which the e-commerce appliance proceeds to map the intercepted transaction data to the recipient data format as identified in the corresponding data mapping requirements. 
   If the data mapping for the intercepted transaction is determined not to be fully functional, then the operation of the e-commerce appliance  110  continues at process block  330 . Specifically, the discrepancies causing the data mapping not to be fully functional are identified with reference to the corresponding data mapping requirements posted on the data mapping database  130 . At process block  340 , if it is determined that the discrepancies can be repaired, then the operation of the e-commerce appliance  110  continues at process block  350 . There, the data mapping discrepancies are repaired with reference to the corresponding data mapping requirements. If, on the other hand, the data discrepancies cannot be repaired, then the intercepted data is routed back to the initiator along with information that identifies the particular reason for the discrepancy (i.e. why the transaction is being returned or rejected). 
   In one embodiment, the data mapping requirements posted to the data mapping database  130  are actually derived from the requirements of the initiator and recipient application software  152 / 172  and the different formats of transactions processed by those applications. With reference to  FIG. 4 , an example transaction is illustrated in accordance with one embodiment of the present invention. In the illustrated embodiment in  FIG. 4 , thee-commerce appliance  110  derives the data mapping requirements for a purchase order  400  from the initiator formats  420  and recipient formats  440  for data fields  410 . Further illustrated are examples of initiator data field values  430  and recipient data field values  450  according to their respective formats  420 / 440 . As can be seen, for many of the data fields  410  the data remains in the same format; therefore, no mapping is required. Other data fields  410  do require mapping, either to reformat the data to conform to the recipient format  440 , or in some cases to change the data field value  430 / 450  altogether (i.e. to translate or transform the data) to conform the initiator data values to certain customary recipient data values. 
   An example of a mapping requirement to reformat the data to conform to the recipient format  440  is shown in several of the data fields in the illustrated purchase order  400 . For example, if the initiator of the purchase order  400  is an American buyer, and the recipient is a European seller, the data field Date  411  is formatted as month/date/year (e.g. 09/30/2000) using the initiator format  420 , but as day/month/year (e.g. 30/09/2000) using the recipient format  440 . Similarly, the data field Street Address  415  is formatted with the street number before the street name using the initiator format  420 , but with the street number after the street name using the recipient format  440 . The data field Phone Number  416  is formatted as 10 digits using the initiator format  420  but as 15 digits using the recipient format  440 . 
   An example of a mapping requirement to change the data field values altogether to conform the initiator data values  430  to certain customary recipient data values  450  is also shown in several of the data fields in the illustrated purchase order  400 . For example, the data field Quantity  419  and Units  421  are expressed using the initiator format  420  for the United States Customary Unit (Avoirdupois Weight) for weight in pounds, or as shown in the example  430 , 10 pounds. But in the metric equivalent of weight for the European recipient format  440 , the data field Quantity  419  and Units  421  must be expressed in terms of kilograms, or as shown in the example  450  as 4.536 kilograms, thus requiring the data field values to be transformed or translated from the American value to the European value. Another example is if the initiator purchase order  400  is missing a value for the data field country telephone code  417 . A data mapping requirement might be to read the data field country name (not shown) and use a look-up table to determine the corresponding value for the data field country telephone code  417 . 
   Numerous other mapping requirements may be derived depending on the type of transaction and the various initiator formats  420  and recipient formats  440  involved in the particular exchange of data. Once derived, the e-commerce appliance has three possible courses of action. The first two courses of action have been previously described as 1) to map the intercepted transaction data to the recipient data format  430  as identified in the corresponding data mapping requirements, and 2) to determine that the mapping requirements are not fully functional and return the intercepted transaction data to the initiator for further processing. As illustrated in the example in  FIG. 4 , in one embodiment the mapping may require reformatting the data or converting the data to an altogether different value. In one embodiment the return of an intercepted transaction to the initiator may entail also returning information identifying the nature of the discrepancy in the initiator and recipient data formats. This may include not only returning the information about the intercepted transaction the initiator, but also to the recipient. The third possible course of action is to further determine that the discrepancies identified for the intercepted transaction are such that they may be ignored or bypassed without harm to the exchange of data between the initiator application software  152  and the recipient application software  172 . For example, the data field for title  412 , such as shown in the example  450 , Mr./Mrs./Ms/Herr/Frau, may be deemed as not required and the recipient may accept the initiator purchase order  400  without data specified for the data field title  412 . 
   Referring now to  FIG. 5 , wherein a block diagram of a general-purpose computer system upon which an embodiment of the method and apparatus for interfacing application systems via a communications network may be implemented is shown. As illustrated, general-purpose computer system  500  comprises a bus  501 , or other communications hardware and software, for communicating information, and a processor  502  coupled with bus  501  for processing information. Computer system  500  further comprises a random access memory (RAM) or other dynamic storage device  502  (referred to as main memory), coupled to bus  501  for storing information and instructions to be executed by processor  502 . Computer system  500  also comprises a read only memory (ROM)  503 , and/or other static storage device, coupled to bus  501  for storing static information and instructions for processor  502 . Mass storage device  504  is coupled to bus  501  for storing information and instructions. In one embodiment, mass storage device  504  includes a repository for storing the data mapping requirements in data mapping database  130 . 
   Furthermore, mass storage device  504 , such as a magnetic disk or optical disk, and its corresponding disk drive, can be coupled to computer system  500 . Computer system  500  can also be coupled via bus  501  to a display device  521  for displaying information to a computer user. Display device  521  is used to display a graphical user interface to the data mapping database  130  or to other aspects of the present invention. Display device  521  can include a frame buffer, specialized graphics rendering devices, a cathode ray tube (CRT), and/or flat panel display. An alphanumeric input device  522 , including alphanumeric and other keys, is typically coupled to a bus  501  for communicating information and command selections to processor  505 . Another type of user input device is a cursor control device  523 , such as a mouse, a trackball, a pen, a touch screen, or cursor direction keys for communicating direction information and command selections to processor  505 , and for controlling cursor movement on display device  521 . This input device typically has two degrees of freedom in two axes, a first axis (e.g., the x-axis) and a second axis (e.g., the y-axis), which allows the device to specify positions in a plane. However, this invention should not be limited to input devices with only two degrees of freedom. 
   Another device that may be coupled to bus  501  is a hard copy device  524  which may be used for printing instructions, data, or other information on a medium such as paper, film, or similar types of media. Additionally, computer system  500  can be coupled to a device for sound recording, and/or playback  525 , such as an audio digitizer coupled to a microphone for recording information. Further, the device may include a speaker that is coupled to a digital to analog (D/A) converter for playing back the digitized sounds. 
   Network interface card  526  is coupled to bus  501 . Network interface card  526  is further coupled to an external computer network (not shown). Network interface card  526 , in conjunction with appropriate data communications protocols (e.g., the TCP/IP suite of internetworking protocols), provide the means by which an embodiment of the present invention operating on a general-purpose computer system  500  exchanges information with other devices coupled to the same computer network. Modem  527  is coupled to bus  501 , and provides an alternate means of exchanging information with other devices for which a modem connection to an external computer network or device (not shown) can be established. 
   Computer system  500  and application instructions, logic, firmware, or software, stored and executed therein as part of the method and apparatus of the present invention, operate in conjunction with an operating system with graphics capability, such as Microsoft&#39;s Windows or Windows CE operating systems. Commercially available computer systems implementing the features of general-purpose computer system  500  include a broad range of operating system-based computers, including server computers, desktop computers, workstations, personal digital assistants, devices, or other computer appliances. Furthermore, the present invention may be used in conjunction with various browsers (e.g. Microsoft Internet Explorer or Netscape Navigator) designed for both conventional and wireless web servers and various electronic mail applications (e.g. Microsoft Outlook, and Lotus Notes) or other messaging applications to yield an operational platform upon which an embodiment of the present invention may be implemented. 
   Accordingly, a novel method and apparatus is described in which an e-commerce appliance facilitates the interface between disparate application systems via a communications network such as the Internet using a commonly accessible data mapping database. From the foregoing description, those skilled in the art will recognize that many other variations of the present invention are possible. In particular, while the present invention has been described as being implemented in components of the initiator system  140 , the recipient system  160 , an e-commerce appliance  110 , and a data mapping database  130 , some of the functions performed by those components may be distributed in other components of a general-purpose computer system  500 . Thus, the present invention is not limited by the details described. Instead, the present invention can be practiced with modifications and alterations within the spirit and scope of the appended claims.
