The Center For Disease Control And Prevention Information Platform Based On The SOA Design And Development

Through investigation and research of the Centers for Disease Control and Preventioninformationization, we can find that the informationization process from scratch, from the simpleto the automatic processing data business, from a single software maintenance to their overallintegration management. Currently the software and provider of many types of software use andmanagement put forward higher requirements. Development of an integrated information platformfor the integration of software from different vendors can largely enhance managementeffectiveness, improve work efficiency, saving time cost.System design at the beginning of the system to analyze the key technical problems in theintegration of the various subsystems integrated into a unified information platform process, theneed to solve the unified identity authentication, data synchronization, data sharing and other issues.Development of desktop software to complete the preservation of the identity of the state, sendingthe authentication function, the use of this non-standard way to solve single sign-unifiedauthentication. Complete the synchronization of data using the push-pull of two different datatransfer mode depending on the application scenario. Limiting operating authority, control data,and delete data coverage completed version data sharing issues arise during.Integrated design platform based on SOA, based on the software into the presentation layer,distributed services layer, application service layer, domain layer, data layer, the base layer of thesix layers, each layer structures are characterized by the use of software design methods and framemode. Existence presentation layer B\S and C\S two software structure, respectively, using MVCand MVVM framework model development; distributed services layer using WCF and configureSOA implementation-defined interfaces; domain layer is based on DDD design; data layer using,unit of work, Entity Framework data persistence and database operations.The main features include an integrated platform of three main subsystems, platformmanagement system, the client system. Each subsystem is the original system only requiresauthentication, data synchronization and data sharing modifications. Platform management systemneeds to achieve business reports, software management, message management, integrated faremanagement. The client achieve a unified identity authentication, data synchronization, software upgrades and other functions. All of these basic functions to achieve customer demand for theplatform.
