Research Of Integration Based On Semantic And The Development Of Support Tools

Nowadays more and more application integration needs to perform the integration via the real-time data exchange among the data scattered in different locations and with various autonomy languages and working environment, so that an online integration environment is required free from support platforms and language differences. In this context semantics-based integration is presented. On the basis of an unified information exchange model, semantic data object links the applications and data sources throughout the enterprise, while the design engineers are just to develop business-oriented integration application components on the semantic transmission layer. In addition, communication between people and computer is realized by predefined semantic rules, enabling there generalized integration on operation layer.Based on the research on the semantics-based integration technology, this thesis presents the multilayer integrated model and overall architecture based on semantic data and builds the information integration software system which is of information exchange, semantic conversion and dynamic tailoring integration model. An equal, open integrated environment is created in terms of the integration software system, improving operating efficiency by reducing integration difficulties and risks, shortening integration times and enhancing the integration width and depth. The integrated approach is also presented of getting data rules source dynamically based on semantic analysis.The solution is proposed and used in the integration architecture against the technical difficulties such as semantic object conversion, communication function implementation, integration strategy realization and the support tool design, etc. A detailed description specification is established for application system to shorten integration time and improve integration efficiency. The integration architecture is coupled with semantic conversion tools, ensuring the consistency of the semantics. The integration architecture is able to link to the applications systems in loose coupled manner, facilitating to enhance integration support tools. The tree control component is planned based on dynamic semantics analysis rules.In the end of the thesis, two integration examples, file format integration between CAPP and Word and PDM signal system design, are introduced to verify the feasibility and usability of integration architecture.
