The Optimization Study On Information System Integration Of Finance And Business Functional Design

With the changing of the knowledge economy, the worldwide capital markets and the equity markets increasingly grow and develop. The information needs of accounting information users increase tendency of the diversity and individuality. At present, the integration of finance and business functional in the popular software does not meet the needs. In order to meet the inherent requirements of the new economic era of information needs, we have optimize necessarily the integration of finance and business functional design. The starting and the end point should be changed the traditional value law point, and the sorter events approach founded in1969will applied timely.Sorter events approach, which was bred, the late60s of last century, in the US, restricted by the economic environment at that time, its all theory views were not clear. From the historical background of the sorter event approach, based on the historical angle of sorter events approach prototype might be annotated as "the extension of the accounting recognition events beyond the mere value category, the basic accounting theory under the sorter events approach is directional benchmark of event" and so on. After analysis, we found that sorter events approach and present the information needs are the same.After decades of environmental changes, in particular, the constantly upgrading of computer information processing technology level and the growing demand for integration of finance and business, the Sorter events approach applies in the current environment becomes even more feasible and urgent at the right moment. The necessity of its application is that the functional design of the integration of financial operations of today’s information systems has many deficiencies. The main shortcomings of the integration of finance and business functional design are just as followed:the design of information systems is still based on traditional functions of the position; the data transfer between the business subsystems and accounting subsystem could easily lead to redundant and so on. The feasibility of its application is that feasible objective conditions, the sorter events approach of law superiority and the sorter events approach fit for the essence of the integration of finance and business.According to the structured information system development methods, the optimization design of integration of finance and business based on the sorter events approach are logic design optimization and physical design optimization. The logic design program is also called system analysis, which has the TFD of integration of finance and business, the DFD of integration of finance and business, the transaction processing flow chart and the events data dictionary. The physical design program based on the logic design program has the system overall design program, the code design program, the data storage design program, the input/output design program.The innovation the main works of this paper are as followed:(1) Based on the historical angle of Sorter events approach Prototype, interprets clearly the basic view of the Sorter events approach, revealing the essential connotation of the "events", unlike based on the modern angle of Sorter events approach in the past.(2) The current mainstream accounting information system software does not include the production management subsystem, the functional design of information system integration of finance and business under sorter events approach make purchasing, inventory, production, sales as a whole, building events of information sharing platform, which truly reflect "the homologous divergence" in the financial accounting and management accounting and operational matters dealing with the accounting treatment.(3) Detailed events table is the only storage issues certificates in the computer instead of the voucher, making data integration; automatically generated certificate program will be some of the issues of data conversion for vouchers data into the accounting processing chain; storage and output isolation technology makes the multi-information sharing; the accounts processing files such as temporary voucher, history voucher and books, are just a logical storage, which do not take up physical space, ensuring the data store only once and output repeatedly.
