The Design And Its Implementation Of BEPS System In Commercial Banks

Bulk Electronic Payment System (short for BEPS) is an important application system of China's National Advanced Payment System(short for CNAPS).It is a bank_crossing bulk payment platform, either credit or debit, for commercial banks ,enterprises and individuals. It is designed for supporting varieties of payment tools.BEPS provide large-amount and low-price payment services for society.It will promote financial services of whole society. Connection to BEPS of commercials banks is an integrated plan of Center Bank of China, as well as a need of competition.This paper discusses constructing the inner system to connect BEPS based on current information system framework of commercial banks. This system can provide all functions of BPES for bank customers. The main functions of this system include: Common Credit Remittance, Common Debit Remittance, Fixed-period Credit Remittance, Fixed-period Debit Remittance, Realtime Credit Remittance, Realtime Debit Remittance, Query and Query-Back, Free Format Query, Collation and Roll,Print and Running Controls.We adopt data-flow-oriented structured methods for requirements analysissince banking business is a series of proved processes. The main requirement analysis tool is DFD .We adopt structured design methods in primary design and use conversion analysis methods to conduct out diagram of program modules. On conceptual data modeling, E-R diagram is the main tool. Description of kernel data structures is also listed.In order to deal with a large amount of concurrent transactions and high-frequence database access, a 3-tier software structure is necessary for the aimed system. We deploy CICS on application server and Sybase Adaptive server on database server .In this paper, we mainly discuss the logic of second tier since business logic is the kernel of 3-tier application.In this project, the author have taken part in software requirement analysis,primary design,detailed design.
