Extending Object-relational Database to Support Spatio-temporal Data*
نویسنده
چکیده
Object-Relational Database (ORDB) techniques are developed rapidly in recent years and widely used for spatial data storage and manipulation. The ORDB has strong basis both on theories and applications, and if well extended, it can also be used to handle spatio-temporal data. Although ample research on spatio-temporal data modeling has been performed, very little work exists on how to implement a spatio-temporal information inside an ORDB. This paper aims at building spatio-temporal database system from design to implementation via extending object-relational database, including design spatio-temporal object model and a general spatio-temporal data model, then implement a spatio-temporal information system based on these model proposed, last a case study on practical spatio-temporal data handle examined. * Supported by the Chinese National Fundamental Surveying and Mapping Project Foundation of China under Grant No.1460130524207; the National High-Tech Research and Development Plan of China under Grant Nos.2006AA12Z214; the National Grand Fundamental Research 973 Program of China under Grant No. 2006CB701304; the Open Foundation of Key Laboratory of Geo-information of SBSM of China under Grant No.B2618.

Language Bindings for Spatio-Temporal Database Programming in Tripod
While there are many proposals for spatio-temporal data models and query languages, there is a lack of research into application development using spatio-temporal database systems. This paper seeks to redress the balance by exploring how to support database programming for spatio-temporal object databases, with specific reference to the Tripod spatio-temporal OODBMS.
متن کاملReasearch on the Change-of-feature Based Spatio-temporal Object Relational Data Model
The spatio-temporal data is our cognition to external matter and the spatio-temporal data model is the fundamental basic to manage the spatio-temporal data. The spatio-temporal object is always changing so we need a spatio-temporal data model which can reflect the change information and change reason and roundly and exactly describe the spatio-temporal world. At the same time more and more dema...
متن کاملMaintaining Semi-structured Spatio-Temporal Data Based on Nesting-Relation-Oriented Model
semi-structured spatio-Temporal data has become prevalent with growth of GIS. In this paper, we propose to use “Nested” natural of spatio-Temporal data to storing & maintaining it efficiently in an Object-Relational Database based on Nesting-Relation-Oriented data Model– one of N1NF database. This model not only reflects the nested structure of semi-structured spatio-Temporal data, but also dis...

Composition of time and space in a unified data framework results into spatio-temporal databases. Spatiotemporal Database Management Systems (STDBMS) are able to process, manage and analyze spatiotemporal data. Spatial TAU 1 (STAU), developed in [Pel02], provides spatio-temporal functionality to Oracle10g Object-Relational Database Management System (ORDBMS). Although STAU is designed in a way ...
