Research And Application Of The Case On Enterprises' Heterogenous Data Integration

With the fast development of the world's economy, the circumstance of enterprises also had a very big change. No matter how it was useful or useless in the department of informatization construction, those applications are ignored now. It is very important for enterprises' informationization construction what kind of software should be designed to be suitable in the so fast development environment, and make use of those neglected application systems. It is established a plan for heterogenous data integration that do very important contribution to the corporations' development and construction of informationization.Firstly, It is researched and analysed that some technology in heterogenous data integration in abroad and domestic and some cases on heterogeneous data integration; It is studied that the main Characteristic of the most popular software ideological system, which named SOA, as well as the characteristic on the different technology to realize it. It is mainly described that the characteristic which built the SOA system based on web services composite technology. Analysed a popular construction based SOA ideological system detailedly, which named Enterprise Service Bus.Secondly, it is proposed a case that on heterogeneous data integration on the basis of Web Services integrating technology and reference framework of SOA ideology and the merits of ESB in application. A composition algorithm named non backtrack backward chaining was used in the case, and built a execute case for a collection of web services dynamically. The algorithm of non backtrack backward chaining was researched and analyzed detailedly. The algorithm was improved and further improved efficiency of the algorithm. Finally, the improved case was carried out in the manufacture enterprise and had a successful application.The practice applying is indicated: the system has a standard structure, a good expansibility and easy to apprehension and design. Especially, it had a very good self-organization construction and simple maintenance. It will bring the important effect in the enterprise development and their informatization construction.
