摘要
In order to adapt to the specific application environments of power system, based on the relational database index management mechanism, this article proposed an efficient index management technique for real-time database. This technique combined the advantages of both hash index and B+ tree managements, fully utilized the memory resources as well as the concurrent processing characteristics of computer, and eventually achieved real-time massive data real time insertion and query.
