Augmenting Traditional ER Method to Support Spatiotemporal Database Applications
نویسندگان
چکیده
In this paper, we present a new conceptual modeling tool, called STXER (SpatioTemporal eXtended Entity-Relationship), to support spatiotemporal database applications. STXER provides most functions for database conceptual modeling, such as graphical user interface, SQL script generation, XML schema definition, and commercial-DBMS-oriented database creation. Compared with previous tools, STXER is ER-compatible and supports richer spatiotemporal semantics. Thus it can support both non-spatiotemporal and spatiotemporal 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.

Research on Unified Spatiotemporal Data Model
Spatiotemporal data model, which is the basis of spatiotemporal data management, deals with the representation and manipulation of spatiotemporal data. So far many spatiotemporal data models have been proposed, but most of them are towards specific applications and few are for general purposes. It is not feasible to design respective data management systems (DBMS) for different applications bec...

In order to eliminate data redundancy of spatiotemporal database, and flexibly create spatiotemporal association patterns, and fast discover spatiotemporal association rules, firstly, this paper adopts event-coverage to create spatiotemporal mining database; the method can divide the spatiotemporal domain into some spatiotemporal transaction cells, where each cell is made of attribute values an...
متن کاملConceptual Data Modeling for Spatiotemporal Applications
Many exciting potential application areas for database technology manage time-varying, spatial information. In contrast, existing database techniques, languages, and associated tools provide little built-in support for the management of such information. The focus of this paper is on enhancing existing conceptual data models with new constructs, improving their ability to conveniently model spa...

Nowadays, the geographic metadata are defined by ISO standards and their particular goal is to assist the data exchange between different users and to provide the data quality information. However, these metadata are defined for static data processed by traditional applications. Such metadata do not take into consideration the qualification of dynamic data resulting from mobile and agile object...
