Applied Research, Real-time Memory Database Technology To Mobile Boss

With the proliferation of the phone users and the challenge of the market demand, the Business and Operation Support System (BOSS) of telecommunications industry need to deal with two problems: mass data and real-time business. A real-time system with greater efficiency of data access and high usage of CPU and memory adopting the technology of Main Memory Database is chosen to solve these two issues. A new application model of BOSS is proposed through research on real-time main memory database, which overcomes existing efficiency problems of the system based on Disk Resident Database.Based on the previous research on real-time main memory database of BOSS, a new model named multi-process real-time memory database model (MRMDB) is presented in this paper, which applies MDB service subsystem of the system mesosphere in the three layer construction to achieve interactive access between application and memory database. An improved RMDB-T tree is involved in this new method. For high performance, a tail node for storing dynamic data is added to the T tree node, when it adds or delete data frequently. Furthermore, a policy of swapping data between memory database and external storage based on Access Data Set is used to reset memory database.It implements application MRMDB model in Real-time Accp-Sum system which is a key subsystem of BOSS. It involves control over data and multi-process validation, application of mdbparser and RMDB-HA fault recovery which is combining Synchronous Replication to Asynchronous replication in order to make the system restore properly. The result shows that the mechanism and policy of MRMDB is able to handle business accurately with superior performance.
