The Research Of DTS Data Management Based On PC

A new database application that combining an offline database and a dynamic database is discussed for managing lots of data and being required with fast I/O in Dispatcher training simulator (DTS). The large relation database Oracle DB is used as offline database. The database in the DTS is required with real-time I/O. To this question, a method combining memory database and objective database is raised. The active database has fast I/O,no redundancy operations and send data to users actively. With using this method, the performance of database in the DTS is remarkably improved. This paper presents a new practical and fast calculation method of network topology. After forming logic network, breadth-first search in local range is used for switches'operations. The searching is based on hierarchical data structure of Physical node-equipment. This method is not influenced by the connection and initial condition and the method is effective and applied.
