摘　　要：分布式信息共享平台(DISP)实现了大型业务处理系统信息化过程中的互操作性,解决了"信息孤岛"问题,达到了信息共享的目的。该平台位于客户机服务器的操作系统之上,在多级网络环境下管理计算机资源和网络通讯,是MVC体系中业务逻辑中间层的支撑平台。它能在统一框架下,完成不同操作系统以及不同或相同数据库间数据透明可靠传输、复杂交易处理和数据库复制的功能,从而实现了分布式系统的数据一致性和完整性。From the perspective of technology, DISP considers, practically, how to realize the interoperability of very large transaction processing systems and eliminate 'Information Island' during the process of information integration, thus to achieve information resouces sharing. DISP runs on the operating system of client & server, supervising the computer resources and network communication in muti-level network system. It is the middleware platform that upholds the control logic in the architecture of MVC. In a general frame, DISP is platform-neutral and could achieve reliable and transparent data transmission, complex transaction processing and database replication between homogenous or heterogenous DBMSs. As a consequence, the data consistency and integrity are realized.
