Application of Timesten on Web-Based Monitoring System

In order to gain high response speed, the paper presents a hybrid Timesten and Oracle database structure. First, the paper creates concepts of real-time database and historical database. It also points out their relationships. Second, it builds a hardware structure which involves an application server, a Timesten database server and an Oracle database server. The structure adopts uninterruptible power supply for data reliability. Last, it presents a software structure of databases. The Timesten acts as the real-time database and the Oracle acts as the historical database. There is a layer in front of the Timesten for data acquiring and an agent layer between the Timesten and the Oracle for data transmission. Experiment shows that the Timesten is about 6.69 times faster than the Oracle disk database.
