Most researches in spatiotemporal database focus on data model and query processing, and few are towards the implementation of spatiotemporal database systems. In this paper, we present OSTM, a spatiotemporal database module which is extended on Oracle9i. As an Object-Relational DBMS, Oracle provides extensibility of data types and functions for complex applications. Based on our previous spatiotemporal data model, we develop spatiotemporal data types and functions for Oracle9i. After a brief introduction to the spatiotemporal data model, the implemental details of OSTM are discussed. OSTM supports traditional SQL language and thus provides a practical way for spatiotemporal data management.
