There is some case management system software in today's market in China. But their functions are commonly simple, only for case input and query.This article in view of DSSs'research present situation and development tendency, and discussed DSSs, which based on Data Warehouse, structure and its the characteristic. Elaborated the construction establishment step of DSS. And propose application in the telecommunication industry, combing the knowledge of DSS. Research the solution of the tele-DSS, taking the data warehouse as the core.
