Design And Implementation Of Financial Information System Integration Platform Based On Open Source ESB

With the deepening of financial information construction,data sharing and interaction between financial systems at all levels has become more frequent.In the early stage,it can be realized through the interface between systems,but as the connection methods such as interfaces continue to increase,more and more problems are encountered:(1)The provincial and municipal financial system interfaces are numerous and complicated,and maintenance management is difficult.The connection between the financial system and the correspondent bank's dedicated line is inefficient and costly.(2)Financial data integration standards and specifications are confusing.(3)When the provincial and municipal financial systems are integrated,complex data conversion and calculation are more,and simply defining interfaces and other methods can no longer meet the demand.For decades of financial informatization development,it is impossible to redesign or develop all systems at this stage,and it is necessary to realize system integration based on data sharing without changing the system or with little change.In view of the above problems,this paper is based on the financial information system integration platform of SOA(Service-Oriented Architecture),and designs and implements data exchange standards and interface service specifications,financial integration libraries and conversion computing services for the financial industry.The solution realizes the integration of financial information systems with data integration as the core.The main work of the thesis includes:1.Researching the development of integrated technology at home and abroad,combined with the status quo of China's financial informationization,proposed the overall design of the financial information system integration platform based on open source Mule ESB,and realized the data integration of heterogeneous financial information system.2.The design conforms to the financial industry interface service specification and data interaction mode scheme,and solves the problems that the financial industry data standards are not unified and the integration process is not standardized.3.The financial integration library scheme consisting of designing the basic information base and the data exchange library solves the problem of updating and synchronizing the large data volume in the process of financial data integration,and provides support for the later financial data analysis and decision-making.4.Design complex data mapping conversion strategy to solve the problem of data elements and subject system inconsistency in the data integration process.5.Design loop detection algorithm based on dependent sorting algorithm and directed graph,which solves the problems of large amount of data transmission and formula calculation of provincial and municipal financial information systems.On the basis of the above work,the practical financial information system integration platform is realized and tested and verified.The experimental results show that the solution is effective and can meet the needs of financial information system integration.This paper is aimed at the problems encountered in the integration process of a municipal financial information construction project,and proposes a data integration solution based on the open source Mule ESB as the core financial information system integration platform.The program draws on and summarizes the UF company's finance.Construction experience in industry data integration.This program has been implemented and put into operation,and it is practicable after practice testing.
