Recently, there has been a fast proliferation of applications creating spatio-temporal data that has to be processed, stored and queried efficiently. Consequently, there is a need for spatio-temporal data management systems that are able to support such storage or query operations. Spatio-temporal data management based on ORDB was derived in this paper. After bringing forward the structure model of spatio-temporal data management, one actual STDMS (Spatio-Temporal Database Management System) TspatialService was designed and then implemented. The system is based on data model of Dynamic Field and accomplished through spatio-temporal extension on PostgreSQL. Various spatio-temporal operations could be carried out in the system through simple SQL statements as well. By using the system, effective spatio-temporal data management was achieved.
