Research And Realize On MIS System Based On Smart Client

The rapid development of information technology, which has already been the tendency for global development, has greatly accelerated the modernization and informatization for enterprises. So on the basis of analyzing the present researches on Offline Work both at home and abroad, this paper mainly studies the application of Offline Work to Smart Client, which combines the advantages of rich client application as well as the deployment and administrable of thin client application. So that it can achieve the balance of using resources. And then provides relevant solutions to existing problems about the applications of Offline Work on MIS System.As for the designing and researches of MIS System applied offline, this paper focuses on the following work: Extending office application on the basis of Offline Application Block and providing an integrated system for class library or API, which makes enterprise exploration easier; Constructing offline application of Smart Client on the basis of SOA framework, which builds a set of framework suit for application and exploration of enterprises including scrutiny, service request, service search, service supply and service security; Studying the algorithms for network condition, the strategy for refreshing Data Caching, the Data Synchronization Strategy and the Data Concurrency Strategy; then realizing the distribution eruption of transaction through Web Service and MSMQ; By using Microsoft Visual Studio .NET 2003, constructing the exploit environment based on offline application of Smart Client, with the help of offline Application Block and Update Application Block of Microsoft; then using XML Web Service to access the server in order to realize the operation, auto deployment and update for database; and the research for the structure of service-oriented Smart Client program going step further.
