Abstract  This paper introduces the design and implementation of a predictable multi-threaded main-memory storage manager (CS20), and emphasizes the database service mediator(DSM), an operation prediction model using exponential averaging. The memory manager, indexing, as well as lock manager in CS20 are also presented briefly. CS20 has been embedded in a mobile telecommunication service system. Practice showed, DSM effectively controls system load and hence improves the real-time characteristics of data accessing.

Key words： main-memory database(MMDB)      database service mediator(DSM)      hash indexing      lock
