Construct Efficiency Improved Bank Business Management System Based On SOA

As the time for data concentration of domestic bank is coming, the problems of processing efficiency of business management system resulted from mass data are needed to be solved immediately. In this paper, above issue is analyzed from management aspect, and the reason is found in the overreliance of information technology, the insufficiency of scientific business process optimization, and the absence of whole system architecture combined by IE and IT. Moreover, the lack of methods and tools for bank system analysis and design will make it is hard for bank to construct system architect with high efficiency and business that could be altered with requirements. So the paper integrates the theories and methods of management, finance, system science and software engineering, and systemically researches the theory foundation, technical system, implementary strategy and application method of service-oriented architecture (SOA) based on the principles of IE + IT. The aim is to establish an efficiency enhancement oriented bank business management system, and provide theoretical instruction and technical tool support for the bank informationization.First, by researching the status of management system analysis and design of domestic bank, the significant meanings to develop system analysis and design research based SOA is revealed.Second, the research literatures in relevant research field of management information system are analyzed, which provides research thoughtway and technique support for analysis and design of bank business management system based on SOA.Third, by the analysis of the features of SOA method and relationship between business and IT in Enterprise Architecture (EA), the SOA design principle and the way to realize services in SOA are described. Based on the description of service-oriented model and architecture, the service exposure and service realization during the service-oriented analysis and design are analyzed both in quantity and quality in a creative way, and the standard and method for determining service granularity in bank management information system based on SOA are put forward. Above research results provide necessary theory foundation for the construction of business management system based on SOA by bank.Forth, the features of business management flow are analyzed. Based on the method of IE + IT, the optimization of business flow and improvement of system architecture are executed at the same time. The mass data are processed with ETLRI, and the data amount needed to be processed concentratively is significantly decreased. The design principles based on SOA and the actual conditions of domestic banks are combined, and with the aim of improving the efficiency of data processing, the design scheme, architecture system and data model of business management system based on SOA are studied.Finally, by the application of above research results, the empirical researches is made using bank P as an example. The research results indicate that the data processing efficiency of business management system based on SOA constructed with IE + IT method is improved significantly. It is also proved that the principles, models and methods of SOA will give important guide to the implement strategy of informationization of domestic bank, and have strong operability. Based on SOA, Business Process Reengineering (BPR), Enterprise Application Integration (EAI) and multi-channel service of"design– improvement– informationization"management amelioration mode could also be effective for fast improvement of management level of domestic bank industry.
