Design And Implementation Of The E-Governor Application And Approval Online System Based On The J2EE Framework

With the rapid development of network technology and communication technology, the E-Governor has become the head of the five "information freeway" applications. Through the E-Governor, the efficiency of handling affairs in the government can be improved greatly. Application and Approval Online System which combines the G to G pattern and G to B pattern has become an important breakthrough of the informationlization construction of administrative management.In order to develop the more expansible E-Governor system and meet the demand of the Application and Approval Online System, this thesis has chiefly conducted the research of the following aspects:1. Research and application of J2EE component technology and design patternJ2EE technology provides the design methods based on many components and the distributed application pattern of multi-layer, which improves the reusable ability of the application system based on J2EE framework. Combined with the practical application in the development of the Application and Approval Online System, this thesis has studied and analyzed the J2EE component technology and several Design Patterns of J2EE.2. Design of system's framework on the basis of J2EE framework.After analyzing the Design Patterns of J2EE, this thesis puts forward one system framework which is based on the J2EE multi-layer architecture. This framework will meet the need of E-Governor. In order to describe this framework clearly in this thesis, the author uses UML's Sequence Diagram.3. Research and implementation of workflow sub-system in Application and Approval Online System The automatic workflow of application an approval is the most important function in the Application and Approval Online System. Furthermore, how to integrate the workflow sub-system with the Web application also is a key point in our research. This thesis puts forward a design solution of the workflow sub-system in Application and Approval Online System after analyzing the theories of automatic workflow in detail. Besides, the implementation of this solution based on the systemframework is also provided in this article.4. Research and application of XML technology in the E-Governor system This thesis analyses the characteristics of XML document and the feasibility of replacing tables in Relationship Data Base. Based on those researches and with the XML processing technology, the author has resolved the problem how to access the temp data in an E-Governor system. With the result, the operation becomes easier and Data Base is more secure.
