Research and Implementation of Conceptual Modeling Tool for Spatial-temporal Database STXER
Lihua Yue · Jisuanji gongcheng · 2007
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.
