The YHCS2 is a distributed C/S computing platform, which is developed by using CORBA technology and Agent mechanisms on a open network computing environment. It can not only be easy to construct an application's integrated framework and components, but also to support cooperative work. In addition, YHCS2 also can interconnect with other application integration technology distributed object technology and middleware systems .In this paper, we will introduce the research goal design idea computing model and architecture about YHCS2, and also specify the implementation method and technology of both integrated-middleware and soft-components which are two main composed parts of YHCS2.
