Research On Banking Service Intergration And System Buliding With SOA Technology

Commercial banks are being faced fierce competition in the globalization of theinternational financial market. To be a victor of the harsh competition, bank not only hasto rely on advanced financial concepts and products, but also need to be led byadvantaged information technology. SOA, service-oriented architecture for thereconstruction of technology, aims at building middle layer as service applications baseon core banking systems, and thus making banks and financial service providers quicklyand efficiently respond to market demand without complicated enhancement of the coresystems. SOA-based financial service platform brings banks the next two advantages: toimprove the bank's response to market demand, the bank can have sufficient capacity tobuild and deploy a new application service to respond to customer demand and to replaceoutdated applications; to reduce the business risk of maintenance of the high-cost corebanking systems. SOA changes the past model of the application development, withdefining the business requirements as"components"in accordance. The"components"being shared as resource provides the designing method with service centralized forapplication development. SOA can improve IT response capacity to enable bank tosupport real-time changes in the business, ultimately helping bank to change as a servicedrivenenterprise.The subject, base on the instance of"banking service system integration"project, isto solve the existing systems issues of modular packaging, loosely and coupled, servicesharing and technical standards, etc. Then the idea of"service-oriented architecturedesign"will be used to design the implementation method of service-oriented architectureframework applicable to the bank. After research the key technologies to achieve theSOA, the implementation of"banking service system integration"will be performed. Theintegration reconstructs the core banking system backend and rebuilds the businessprocess to meet the requirements of financial products and transaction procedures.During the integration of banking service system, the first issue is to research thedevelopment of SOA and relevant technical standards. Then, deeply analysis of existingbusiness workflow is conducted to package the modules of business process and definethe modules of financial products as well as customer transactions. The purpose is tomake banking business rational. At last, the subject analyzes the functions andperformance of business service layer; researches the common standards of data sharingand exchanging. As well, the subject carries out the method of data switching among thebackend systems with selected the technique applicable to banking service mid-layer forintegration with business layer and application layer, sharing the service and information.
