Research Of The Model Building Of The Enterprises Information System Architecture

The aim of the enterprises exploit the management information system is that to fully utilize a large amount of information in and out of the enterprise in order to manage effectively every link such as strategy, tactics and business. It not only can do business according the plan but also can fully suit the need of the market and society and make the best economics benefit and have a big development in the intense market competition. But a large number of enterprises have not reach the aim that they hoped in using the MIS and just to use it in the low level. It is because of that they did not pay more attention to research the structure of enterprise information system architecture and ignore the research of information architecture that is the important play in the ISA. Therefore, how to build the ISA appears very important and necessary for the information architecture building and to promote the course of the enterprise informationiry.It firstly elaborate the aim of exploiting and using the MIS in Chapter one. And then analyze the effect and problem of using MIS at present and this is why that do not reach the aim of using MIS and finally internal and external experts put froward imagination of building ISA.Chapter two elaborates the background, concept, character, researching direction and summarizes the main content of ISA and problem should be solved in researching ISA.Chapter three firstly show the organization structure chart of ISA and then introduce the definition and basic function of every part of ISA and show the level chart of ISA as well. After describing the structure of ISA, we know that information architecture is the important play in the ISA. This article research the structure, building method, including content, classification, character and the part of information architecture in ISA and then put forward the method and step of building ISA after building the information architecture and then show a flow chart about building the structure.Chapter four gives a example of building ISA according the method which introduced in chapter three.
