| Abstract: | Train Running Information Auto-reporting System transfered the train running information to the control centerby satellite communication. The system had two databasesone for real time data, the other for history data.This systemdemanded high realtime ability . At the same time,the database must be recovered quickly after it fails .It was introduced themethod of database maintaining of the system, and discussed how to implement the plan by data transformation services andjob in SQL server. |
