For field working status of electrical automatic testing system application,in view of all three aspects about flow,data and operation,some advanced technologies like software components,software bus,database and so on are applied to breaking down,packing up and data separating of electrical experiment routines.

Component-based software development methodology for building large and complex applications an ideal solution,software component technology to support software reuse is the core technology,the definition of a good through the reuse of software components to develop application software,can significantly improve software productivity.

As the effective means to compose the expert system,the software components and the platform of expert system have got access to application.

In view of the interoperation and reuse problem in the large distributed information system, this paper promotes a strategy of using CORBA and soft component technology to devel- op ERP.
