A Real-Time Database Index Management Method for Fast Access to Massive Data of Power System

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.
