Research Of Realizing Heterogeneous Data Access Middleware Technology Using J2EE Platform

With the unceasing development of computer and the network technology, as well as the enterprise information construction unceasingly is thorough, and the promotion of the software and hardware resources and the expansion of each kind of application, the heterogeneous database access technology already is a focal point of database research. How therefore uses the existing network resources that realizing the heterogeneous data transplant and the conformity under the multi- systems environment already is the key question of this topic research. This topic mainly the Heilongjiang Province science and technology attack project which manages based on supervisor "face the digital forestry application software research", and essential target of the research is realizing heterogeneous data accessing middleware technology using the J2EE platform for providing the solution to digital forestry system with the heterogeneous and the heterogeneous database data transplant and the data analysis.This article main basis current forestry bureau existing system data heterogeneous question proposed that, and proposed based on the system present situation the solution of data heterogeneous question, mainly realizes under the Internet environment to each kind of heterogeneous database (for example: Oracle, SQL Server and so on) the connection, the access, the transplant, as well as carries on to in various databases data withdraws, and completes the data the conformity and the analysis.The enterprise heterogeneous data accessing system realization involved to the multitudinous technology of middleware, ORM and Hibernate. This article has conducted the thorough research to the essential technology, and proposed the plan of realizing heterogeneous data access in the digital forestry system. Finally, this article has realized the digital forestry system heterogeneous data access that mainly basing on the J2EE platform with the multilayered system structure, and having the union with middleware technology, and using the nowadays most vanguard's data middleware development tool -- Hibernate frame.In the system developing process, the present thesis has utilized the many kinds of advanced technologies by synthesis, and has built close integration between Java front end development technical based on J2EE platform and database middleware Hibernate technology, and has realized the middleware technology and the digital forestry system conformity. It has realized the innovation in the forestry project development technology.The research of this topic will bring the good economical effect for the procedure development. The multilayered development system causes component of the entire development procedure, and enhances the procedure development to be possible to duplicated use, and provides the good module for other procedures developments. The realization of the...
