Based Dynamic Enterprise Modeling, Data Modeling Tools

In modern enterprises, each enterprise's data content and data structures are very different. With the development of enterprises, their business models and data models are constantly changing. If a system can't adapt to business's change, it will likely be the enterprise's obstacle, and even hinder the development of enterprise. In the traditional project development process, the database structure is often the core of system development. Database structure should be defined at the first of project and unless special circumstances it generally does not permit change in the latter part of the project development process. According to the database structure, develop the corresponding function page. If you change the database structure, you need to accordingly change the data access layer, view layer. This process doesn't support the dynamic changes in enterprise business model, and has low efficiency.The dynamic data modeling tool which was discussed in this paper is mainly to solve the dynamic of business needs. The tool includes data modeling tool and page layout tool. Data modeling tools which serialized XML document according to user-defined data structure. And then generate corresponding date model after analyzing XML file. Finally the data model was pushed into database. Page layout tool mainly analyze XML file parsing coming from the client-side, and then generate the corresponding variety of views. Part of the page is generated by configuring, so the system can achieve the purpose that their business changes the purpose of dynamic changes.This paper introduces the dynamic enterprise model, and then it analyzes the dynamic advantages and disadvantages of the traditional ERP and dynamic enterprise. According to the actual needs of company's project development, I designed the data modeling tool based on dynamic enterprise modeling techniques.I study the design of the main system module and then I chew over the system's architecture and database's design. Finally I introduced the result of the date modeling tool.
