Abstract: Based on the study on spatial-temporal semantics, an ER-compatible conceptual modeling approach to spatial-temporal database design is proposed, which is named STXER. The spatial-temporal semantics foundation and the spatial-temporal conceptual modeling procedures are discussed, and the implementation and a modeling example of STXER are presented. The STXER approach can support rich spatial-temporal semantics and thus can be used to suit different types of spatial-temporal applications.
