The Integration System Of The Different Data Source Based On XML

With the sustaining development of the scale of company, the scale of company's information system also increases. Influenced by the different phases of the data management system, technical factors and etc, even in a single company, every department will become a data source. And each data source has its own framework; all of these data constitute the different data source of the company.In addition, the development of the web also leads the company from a single point to the company entity, which keeps exchanging information and conducting business. And the integration of the company's data has changed from the inside integration to the outside integration. Nowadays, the company needs to publish and exchange their information more than at any time before, which will lead to the requirements that more and more company need to visit all sorts of data source. In order to meet this demand we need the system, which can support the integration of the different data source.The thesis first will discuss the difficulty in the process of the integration of the structuralized different source database, the strategy of integration, the technique of integration. Then the thesis will propose an overall project, which can solve the integration of different data source including the half-structured data. And at the same time, the core subsystem-exchange subsystem is realized. Due to the agility and the expansibility of XML language, it can describe data for different applications. Thus, this integration system will use XML model as their public model and all of the different data source will be changed into XML document for the further exchange.
