Accounting Information Systems Integration. Cross-platform

With the wide application of AMIS (accounting management infonnation system) in enterprises and the rapid development of computer network interconnection as well as database interoperability techniques, the more and more high requirements of the Aft/US application have been put forward. It is pressing demand to construct the comprehensive ANUS, which is closely combined with the enterprise抯 MIS (management information system). Besides, it is a new task to be solved in construction of the enterprise抯 information systems. System integration is one of the methods to solve the problem. And the development of the technology of integration has provided the possibility for the comprehensive AMIS. Under the background of the upgrade project of CY-MIS (Chengdu cigarette factory MIS), after studying the AIVIIS theory, this paper discusses the function and architecture of CV-AM1S, especially analyses the integration requirements of CY-A1VIIS. Based on this, the dissertation focuses on the information integration of CY-AIVIIS. According to the real state of CY-AMIS, the information integration mode and its implementation scheme are introduced. On the basis of the system general planning, the thesis discusses the information integration of CY-AIVIIS and provides its information integration mode, which are based on the system integration management that niainly means the system data administration, data integration and partial business process integration management. In addition, the paper divides the system integration into the four levels: network integration, information integration, function integration and process integration, and discusses the contents of the system integration on different levels. At last, the paper discussed the heterogeneous network interconnection and heterogeneous database interoperability under the cross network platform and database platform of CY-AMIS. And the paper gives a basic scheme of data sharing among the different application software, which related to the condition that the general software and self-developed application system arc running together. The conclusions of this dissertation are as follows: this comprehensive AMIS enables enterprises to protect and utilize availably its information resources. Moreover it can better meet the needs of sharing network information resources and implement the system integration at the material flow, the information flow and the financial flow.
