Design And Application Of Data Migration Technology In Credit Card System With Different Data Structure Between PAD And SDB

Whether it is on a UNIX platform, the Windows platform and IBM host platformhas decades of in-depth research. However, the credit card system for our country is arelatively new financial system, also into the people’s attention in recent decades.Discussed in this article is how to combine the combination of data migrationtechnology and credit card system, extract a more complete set of credit card systemmigration methods.In recent years, the credit card as the bank’s main financial products business iscontinuing rapid development. At the same time, the combination of inter-banksystem and internal system upgrade is becoming frequent, and data migration is veryimportant in this process. The difference of architecture between different systemsmakes integration very difficult. Credit card systematic differences by analyzing andsummarizing mainly reflected in the following aspects: the authorization systemmainly uses two modes financial authorization8583message of single or doublemessage; accounts balance and the credit limit of data structures such as a card to anaccount, an account of the multi-card, tree structure of card account; Clearing systemneed to update settlement channel including VISA or MASTER settlement files, CUPtransaction statements, bank self clearing filepath re-planning. The objects above three points in common are the billion of information processing, which isunavoidable gaps in integration process.According to migration projects with large amount of data, this paper focuses onthe migration of the specific implementation, program development,7×24hoursauthorized implementation and data migration process fast fallback.In the main migration process, we described in detail the system migrationplatform construction and its advantages. In data migration, Pingan Bank basiclymaintains the original data architecture of the Vision Plus, and chooses UCF structurein accordance with its own business characteristics. Based on the data dictionary andbusiness logic of the two banks, through the program algorithm data from ShenzhenDevelopment Banks mapped to the Pingan data structure as close as possible in orderto not impact clients.In7×24hour authorized, this article details the the Pingan core mandate systemarchitecture, and a brief introduction to the host and peripheral the authorization datamigration roadmap, uninterrupted authorizing by this architecture. Made a detaileddescription and interpretation of program logic.After the completion of the feasibility analysis of key technologies and methods,the paper involved in part of the system implementation. Credit card overall migrationscenarios are described in detail at the same time, will also previous migrationperformance bottlenecks encountered in the drill process to do a review and analysis.Parameter setting of the host data processing method further summarized. Althoughthis part of the more independent credit card migration program, but can also be givento other host systems employing certain reference for. Finally, we will talk aboutsome simple achievements and scarcities.The innovative points of the paper can be summarized as follows:(1) Research how to integrate data from different structure system to Vision Plus.(2) Detailed data checking blue print in different data integration.(3) Research on backward method on key point of data integration. (4) Transaction replenishing.(5) Online and batch performance optimizing.
