BACKGROUND OF THE INVENTION 
     The challenges of mail delivery within the United States and in the growing ranks of industrialized countries has grown so that, in the United States alone, the postal service delivers approximately 600 million pieces of mail per day. To the growing postal burden is added the requirements of keeping address data accurate in the face of a growing social mobility. To promote operating efficiency, the United States Postal Service (U.S.P.S.) has offered discounts for the use of 5 digit zip codes, bar codes, delivery point bar coding, and various forms of address coding such as those used on the Optional Endorsement Line of printed address blocks. 
     The most common form of coding is directed to the postal zip code. The basic elements of a postal zip code consist of four parts; these are: (i) the “zip code,” which consists of 5 digits and refers to geographic area or zone; (ii) the “zip plus 4” further breaks down a zip code region into smaller sub-regions, this consists of four digits added to the base zip code; (iii) “delivery point digits” which consist of two additional digits that further break down a zip plus 4 so that the U.S.P.S. can more accurately pin point an exact location; and, (iv) a check sum digit. The delivery point digits are extracted from the street line of the address using a U.S.P.S. approved algorithm. 
     But, the best coding systems available are of little use if the intended recipient is no longer at the address that has been coded. Of particular concern to the U.S.P.S. is the relatively high amount of mail that is undeliverable because the intended recipient has moved and not left a forwarding address. 
     With the need to reduce costs while improving the efficiency and reliability of its operations, continuous review of methodology and the systems used to implement operations is continuously required. Review by the U.S.P.S. has led to a series of sweeping changes that are to be implemented in a series of changes grouped together under the banner of “Postal Reclassification.” The first such change occurred on Jul. 1, 1996; the second on Jan. 1, 1997. The new standards under Postal Reclassification will enable the U.S.P.S. to improve efficiency and remain competitive by reducing the amount of work effort required to deliver mail. 
     The change of Jan. 1, 1997 includes standards for a series of move updates that effect address databases. Among the standards are: a National Change of Address (NCOA); U.S.P.S. Address Correction Requested (ACR); USPS Forwarding and Address Correction Requested; USPS Address Change Service; and, access to USPS FASTforward technology. 
     Under the new standards, companies are required to show that they are implementing a process to track a customer&#39;s change of address. The U.S.P.S. requires that companies implement the change of address process against customer information files at least once every six months in order to continue receiving postal discounts for First-Class mail. In addition to maintaining discounts when utilizing certain U.S.P.S. services, companies will be able to add efficiencies by improving their customer satisfaction, reducing postage expenses, and reducing returned mail and rework costs. 
     One of the initiatives of the U.S.P.S., designed to improve the levels of address quality in corporate mailings, has been the development of FASTforward which has evolved from work between the U.S.P.S. and vendors of commercial multi-line optical character readers (MLOCRs). The apparent goal of the U.S.P.S. is to have MLOCR solutions incorporate FASTforward technology to help identify customer change of address information. 
     FASTforward identifies and reads address data from the mailpieces introduced to the system, as well as the ZIP+4 coding, to determine if a change of address notification or forwarding order exists for a given addressee. If a change of address notification or forwarding order is found, then FASTforward has the capability for correcting the destination address on the mailpiece. 
     For those industry vendors developing systems for the mailing and/or addressing market, the U.S.P.S. has promulgated the FASTforward specification and requirements in order to promote uniformity and compatibility in interfacing the vendor product with the U.S.P.S. system. Vendors are responsible for design of the required interface systems. Thus, unique approaches are required for interfacing mailing and address systems with FASTforward in order to provide seamless service for customers. 
     One approach to designing an interface system for FASTforward is to create a client-server environment that provides privacy as well as control of customer data that is provided to FASTforward as well as obtained from it. 
     Therefore, it is an object of the present invention to provide a client-server interface and environment that provides privacy as well as control of customer data when interfacing with the U.S.P.S. FASTforward system. It is a further object of the present invention to utilize change of address information provided by the FASTforward system to return a new address and related data to the customer&#39;s mailing and/or addressing system and to include a graphical user interface (GUI) for easy task establishment and monitoring of the task execution. 
     SUMMARY OF THE INVENTION 
     The invention overcomes the shortcomings and limitations of the prior art and satisfies the intended objectives through a method and system of updating address data representative of a changed address. The method is accomplished by initiating an address data request at a data processing system (client). 
     The address data request is for an update of individual address records contained in the database serviced by the data processing system. The request is transmitted from the client to an application host system such as ForwardTrak. The address data request is translated at the application host system into a format readable by a master system comprising change of address files. In order for the translated request to be transmitted from the application host system to the master system, there must be created an interface that allows passage of the translated address data request from the application host system to master system so that said translated address data request can be read and responded to by the master system. 
     The interface is created during the method&#39;s translation step. The translation step comprises a number of further steps that begin with creating a data map of the data representative of the address data request. The created data map is compared against a second set of data representative of a mailing list correction (MLC) scheme, or a multi-line optical character reader (MLOCR) scheme. The comparison establishes a second data map which is representative of the address request in either the MLC or the MLOCR scheme. The second data map is then transmitted via a SCSI interface to the master system for processing of the address request. 
     The master system, such as the U.S.P.S. FastForward system, matches the address data request to records of address changes that are resident in an address database operatively connected to the master system. After matching the address data request against the change of address database, the method and system determine whether a match exists between the address data request and any address record resident on the address database. If a match occurs, then a record of the match is placed into an address data reply. The reply is then transmitted back to the application host system. 
     When a reply is received from the master system, whether that reply is positive (a match occurred) or negative (no match found), the reply is translated into a format capable of being read by the client data processing system. The translated reply is then transmitted back to the client for use in updating address files operatively accessible by the client data processing system. 
     The address files are updated by entering a new address extracted from the reply format if the result of the address record request was positive; that is, that a match occurred between the request and the master system&#39;s change of address file. 
     The system is capable of printing one or more reports. The reports are based on the transactions between the application data processor and the master system, and representative of the requests, replies, and/or statistics arising from the transactions.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Turning to FIG. 1, there are depicted in block form two subsets that, combined, form an addressing system. In a preferred embodiment, the addressing system is comprised of the United States Postal Service (U.S.P.S.) FastForward system and a client server interface system such as the ForwardTrak system available from Pitney Bowes Inc. of Stamford, Connecticut. A draft copy of the ForwardTrak Operating Guide is attached hereto and is incorporated herein by reference. 
     Addressing subsystem  10  is a representative example of a system that could host the U.S.P.S. FastForward system. The representative system comprises: data processing system  12  which can be a mainframe or midframe computer which in turn is comprised of: a monitor; user interface devices such as a keyboard and/or mouse; RAM and disk drive memory; a modem; a database comprising address correction data; and interface cable  30   a  for providing a SCSI interface connection to addressing subsystem  20 . 
     Addressing subsystem  20  is a client server interface system comprising: data processing system  22  connected to addressing subsystem  10  by SCSI interface connection  30   a . Data processing system  22  can be a mainframe, midframe, or micro-computer which in turn is comprised of: a monitor; user interface devices such as a keyboard and/or mouse; RAM and disk drive memory; a modem; a database comprising address correction data; interface connection  30   e  for connection between the data processing system  22  and a client input station  26 ; and, interface connection  30   b  for connection between data processing system  22  and a server batch driver system  24 . In turn, client input station  26  is connected to interface connection  30   d  for connecting to address database  28 ; and, server batch driver system  24  is connected to address database  28  via interface connection  30   c.    
     A data processing system that can download data that can be printed on a printer, whether that printer is a peripheral device of the data processing system or not, uses application programs for creating data. These are resident in the data processing system ROM memory, additional memory, or external devices such as database  28  can be utilized for the storing of address lists. The printers commonly utilized in the addressing art may also contain a microprocessor that is able to assign bar code data to addresses that are delivered from the host. These so-called “smart” printers vary in their ability to process data. 
     Turning to FIG. 2, there is shown a high level flowchart of the subject method within the system of FIG.  1 . 
     The method begins at step  50  where the system operator initiates an addressing application. The method advances from step  50  to step  52  where the system user calls up an address record from a CASS certified addressing system such as the SmartMailer system available from Pitney Bowes of Stamford, Conn.; or, the system user can simply enter the name and address data as part of a request. The address record can be resident in a database which is located within a memory of the addressing system or can be called up from a remote database. The address data request is transferred to either a client batch driver or to a system batch driver; the request can contain one or more address records to be checked. At step  54 , the batch driver transmits the request via conventional communications means to an interface application resident in a client server system such as the ForwardTrak system available from Pitney Bowes of Stamford, Conn. The ForwardTrak system is the subject of this application; an operator guide is attached hereto and incorporated herein by reference. 
     The interface application receives the address data request at step  56  and begins reformatting the input data from the format of the initiating application to the format of the master system application to which the address data request is to be forwarded. Reformatting of the address data request is completed at step  58  when the interface application simulates an MLOCR interface that is capable of transferring the data via a SCSI connector to the master system application; the method at step  58  is also suitable for use with a mailing list correction scheme (MLC). 
     Once the MLOCR, or MLC, interface is formatted, the interface application invokes the master system application at step  60 . In a preferred embodiment of the present application, the master system application is the U.S.P.S. FastForward system. 
     Once the master system application has been invoked, the address data request is transmitted from the interface application to the master system application at step  62 . The master system application receives the request at step  64  and processes the request by matching the address data request to a list of changed addresses (National Change of Address Database, or NCOA), determining whether or not a match has occurred, and then determining a reply which is to be sent back to the interface application at step  66 . 
     At step  66 , the interface application receives the reply from the master system application. The reply is reformatted by the interface application to a format readable by the initiating application. The interface application transmits the reformatted reply to the initiating application at step  68 . The method then advances to step  70 , where the initiating application utilizes the new address to update the corresponding address record of the address database if the reply is based upon a match found by the master system application in the change of address database; otherwise, the reply simply indicates that no match has been found and the initiating application will process the address data accordingly. 
     From step  70 , the method advances to a query at step  72  which asks whether a next request is to be entered. If the response to the query is “YES,” then the method returns to step  52  where a new address data request is entered; however, if the response to the query at step  72  is “NO,” then the initiating application closes out the data request application. 
     Turning to FIG. 3A, there is shown a flowchart of the method of the address record input up to the point of translation at the interface application of the client server. 
     The method begins at step  100  where the data input sequence is initiated. Name and address data, representative of an address record request, is entered into the application, at step  102 , by either entering the data directly through an operator input device such as a keypad or scanner; or, the data can be brought into the application from an address database. The purpose of the address record request is to determine whether the addressee has indicated a change of address to a master application such as the National Change of Address (NCOA) database. Once the data is entered, the system queries at step  104  as to whether or not the entered data is in a pre-parsed zip+4 format. If the response to the query is “YES,” then the system advances to step  106  where the address data request is sent to the batch driver and then on to a client server system hosting an interface application such as ForwardTrak. The method advances from step  106  to step  118 . 
     Returning to step  104 , if the response to the query is “NO,” then the method advances to a query at step  108  which asks whether or not the data is unparsed and in a non-zip+4 format. If the response to the query is “NO,” then the system advances to step  110  where the address data request is rejected and the system turns to a query at step  112 . At step  112 , the method queries as to whether or not there is a next address data request. If the response to the request is “YES,” then the method turns to re-enter the flow at step  102 . If, however, the response to the query at step  112  is “NO,” then the method advances to step  114  where the application is closed. 
     Returning to step  108 , if the response to the query is “YES,” the method turns to step  116  where the address data request is sent to the batch driver in address line format and then on to a client server system hosting an interface application such as ForwardTrak. The data is received at the client server at step  118  before being translated to an MLOCR or MLC format at step  120 . The translation into an MLOCR or MLC format is detailed in FIG.  4 . 
     Turning to FIG. 3B, there is shown a flowchart of an alternative embodiment of the method of FIG. 3A, wherein the clearance level of the request initiator is checked before the client server prepares the request for translation. 
     The method begins at step  120  where the data input sequence is initiated. Name and address data, representative of an address record request, is entered into the application, at step  122 , by either entering the data directly through an operator input device such as a keypad or scanner; or, the data can be brought into the application from an address database. The purpose of the address record request is to determine whether the addressee has indicated a change of address to a master application such as the National Change of Address (NCOA) database. Once the data is entered, the system queries at step  124  as to whether or not the entered data is in a pre-parsed zip+4 format. If the response to the query is “YES,” then the system advances to step  126  where the address data request is sent to the batch driver and then on to a client server system hosting an interface application such as ForwardTrak. The method advances from step  126  to step  138 . 
     Returning to step  124 , if the response to the query is “NO,” then the method advances to a query at step  128  which asks whether or not the data is unparsed and in a non-zip+4 format. If the response to the query is “NO,” then the system advances to step  132  where the address data request is rejected at step  132  before the system turns to a query at step  134 . At step  134 , the method queries as to whether or not there is a next address data request. If the response to the request is “YES,” then the method turns to re-enter the flow at step  122 . If, however, the response to the query at step  134  is “NO,” then the method advances to step  136  where the application is closed. 
     Returning to step  128 , if the response to the query is “YES,” the method turns to step  130  where the address data request is sent to the batch driver in address line format and then on to a client server system hosting an interface application such as ForwardTrak. The data is received at the client server at step  138 . From step  138  the system advances to a query at step  140  which asks if the request initiator has file access. If the response to the query is “NO,” then the request is rejected at step  132 . However, if the response to the query at step  140  is “YES,” then the system advances to step  142  before being translated to an MLOCR or MLC format at step  142 . The translation into an MLOCR or MLC format is detailed in FIG.  4 . 
     Turning to FIG. 4, there is shown a flowchart of the steps of the translation process that are performed by the interface application. The application begins the translation sequence at step  150  and advances to step  152  where the address data is mapped into either an MLC or an MLOCR format depending upon the requirements of the master system or the system interface by comparing the mapped data to a look-up data of corresponding values to produce either the MLC or MLOCR data map. From step  152 , the method advances to step  154  where the format requirements are performed before advancing to step  156 . 
     At step  156 , the method takes the mapped MLOCR or MLC data and establishes an MLOCR or MLC interface that is capable of allowing transmission of the data, at step  158 , over a SCSI interface to the master system application. The address record request is received by the master system application at step  160 . 
     Turning to FIG. 5, there is shown a flowchart of the method steps that are followed upon receiving the address record file from the master system application. 
     The master system application performs the steps of record matching to determine whether or not there is a match between an address record request and a change of address as filed on the NCOA database. If there is a match, then the master system application will post the new address to the request and return the new file as a reply; in this way, the initiating application can make an appropriate change to its database upon receiving the reply. However, if no match is determined by the master system application, then the reply will contain a notation that no change of address could be determined. 
     The reply is sent by the master system application to the interface application via a SCSI transmission interface. There are three possible alternative replies that can be received: ( 1 ) the addressee has moved and left a forwarding address; the addressee has moved and not left a forwarding address; or, ( 3 ) the addressee has not moved. Upon receiving the reply at step  180 , the system advances to step  182  where it queries as to whether or not the addressee who/which is the subject of the address record request has moved from the address of record. If the response to the query is “NO,” then the system advances to step  186  where the uncorrected (unmatched) address data reply is accepted for translation. If however, the response to the query at step  182  is “YES,” then the system advances to the dependent query at step  184 . which queries as to whether or not the address record has been corrected (a match found) by the master system application. If the response to the query is “NO,” then the method advances to step  186  where the uncorrected (unmatched) address data reply is accepted for translation. The translation of the uncorrected reply from MLOCR or MLC format to the format of the initiating application is performed at step  188  before being transmitted to the initiating application (client) by the interface application (client server) at step  190 . 
     Returning to step  184 , if the response to the query is “YES,” then method advances to step  192  where the corrected (matched) address data reply is accepted for translation. The translation of the corrected reply from MLOCR or MLC format to the format of the initiating application is performed at step  194 . While the translation is being performed, the interface application holds the updated record in memory, at step  196 , long enough to update the interface application (client server) before transmitting the corrected address record to the initiating application (client) at step  198 . After transmission of the corrected address record, the system advances to step  200  where the corrected address record is deleted from the memory of the interface application. If the transmission of the corrected address record at step  198  were to be unsuccessful, then the initiating would have to repeat their address update request. 
     In an alternate embodiment of the subject invention, the interface application queries as to whether or not the transmission to the initiating application was successful. If the response to the query is “YES,” then the system advances to direct the interface application to delete the corrected address data reply from memory. If, however, the response to the query is “NO,” then the interface application, holds the corrected address data file in memory for later retransmission. Attempts at retransmission will occur until the record is purged from the interface application or until the system has received an indication that the corrected record has been successfully delivered. 
     It is to be understood that the present invention is not to be considered as limited to the specific embodiment described above and shown in the accompanying drawings, which merely illustrates the best mode presently contemplated for carrying out the invention and which is susceptible to such changes as may be obvious to one skilled in the art, but rather that the invention is intended to cover all such variations, modifications and equivalents thereof as may be deemed to be within the scope of the claims appended hereto.
