Research And Implementation Of Distributed Data Integration Visual Modeling

With the deepening of enterprise information construction, enterprises build business systems gradually. According to the different need, each unit adopts the different development tool and operating system to build system at the different period. However, because each system can't effectively implement information share and exchange, the traditional system will inevitably lead to information isolated island, application isolated island. A great deal of information has been "locked" in the central application of each islet. Moreover, each "isolated island" can't implement the meaningful exchanges according to the requirement of the customer. From enterprise business needs perspective, it's useful to establish new application system that may integrate the worthy data in original system in order to share the information at the larger scope and utilize the information resources more effectively. The best way to resolve these problems is to build up data integration platform, which could efficiently manage enterprise datasources.The idea of building up three-layer C/S architecture in data integration system is proposed in this thesis in order to make the heterogeneous data visit more effectively in internal enterprise, implement the data exchanging and make the resources shared between enterprises applications. The main contents and conclusions are as follows:1. Visual fusion flow modeling toolkit.It will take a long time to learn how to construct a real-time and correct query. So we develop a visual modeling tool to build queries by way of dragging and dropping. Using the graphical approach, user can save more time which they spend on learning how to construct queries and building queries on demand. There is also one example to show convenience of visual modeling, and have been used in the project.2. RMI in the application of data integration platform.RMI (Remote Method Invocation) of Java expresses the idea of distributed technology and inherits every virtue of Java; therefore it is obvious a very good choice of developing large distributed system. So in this thesis makes an in-depth study of RMI distributed technology, in order to build up three-layer C/S architecture.
