| Abstract: | Based on parallel systemic structure, the Parallel Real time Database is a database integrating the technique, mechanism of Parallel Database and Real time Database, acting according to the mechanism of real time transaction. Importance must be attached to the relation among the data produced by the relation among the Relations in the database. Relational data congregating arithmetic is to avoid dissevering the relations artificially. In the Parallel Real time Database real time is the most important thing. Under the mechanism of real time transaction, the strategy of data storage must be dynamic and seeking of the time equilibrium. |
