The pre time distribution combined real time distribution, not only utilizes time for system more reasonably, but also keeps the efficiency of real time distributing subsystem to deal with RO requests from users.

The critical technology and application of power-system oriented distributed real-time database;

This paper analyzes the function characteristics and structure of the distributed real-time database,data object and transaction s type in industry monitor&control system.

The structure and general method of distributed real time database system ,and the design scheme for connection of distributed real time database, and Web using the great function of JDBC are discussed.

As transactions in distributed real time database systems have to meet the timing requirements, such as deadlines, in addition to the well known characteristics of ACID for transactions in conventional database systems, the traditional transaction commitment protocols and real time commitment protocols developed could not guarantee the atomicity of real time transaction.

In a distributed real time database system, the only way to ensure transaction atomicity is to investigate and develop a real time atomic commit protocol.
