In the structural health monitoring of large-scale construction, a large number of different types of sensor data needs to be processed. Based on the Oracle databases, according to the classification of the sensor and acquisition time, the corresponding database system is established. The system is effective for massive data storage, management, inquiry and dealing with early warning of abnormal data. This article focuses on the function of the database system, the characteristics of the framework structure and composition of the system. At the same time, the vibrating wire strain sensor is used as an example to describe the system characteristics of mass data processed.
