In this paper, we present a CASE tool supporting conceptual modeling for moving objects database applications, which is called STXER (Spatio-Temporal eXtended Entity-Relational model). The main purpose of STXER is to support the database design for moving objects applications on typical object-relational DBMS. The STXER tool enhances the traditional ER model with moving characteristics. It can express rich spatiotemporal semantics for moving objects applications. After an overview of the general features of STXER, we discuss the architecture of STXER. And finally, a case study of STXER’s demonstration is presented.
