Based On. Net Distributed Medical Insurance Management System Design And Implementation

The medicare information system in this thesis is developed for Southwest Power Institute, the .Net based distributed B/S infrastructure is adopted. Distributed technique is an important developing direction of current software development technology. A distributed architecture model under the.NET framework is a model which uses distributed technology and computer network adequately. It can intercommunicate in local area network (LAN)and make long-distance data access in the internet. A typical distributed architecture model under the.net framework is composed of 4 layers: user service layer(USL),business transact layer(BTL),data service layer(DSL)and database layer(DBL).The middle layer which is made up of BTL and DSL is the primary part in the model.USL is the appearance layer of the model. User service is a client which realize in application programs. BTL contains business appearance layer (BAL) and business rule layer (BRL).The former which is used for providing uniform interfaces for basic business object separate client from basic business logic. The later actualize business entity or system object and have to complete all kinds of business rules and business logic. DSL includes data control layer (DCL),data expression layer(DEL)and data access layer(DAL).An insurance system under the model of distributed architecture is an exemplification of the distributed architecture model under the.NET framework. During the period of system designing, the key technique has been analyzed, a reasonable architecture has been constructed, and the whole function of the system has been realized.
