Abstract:Recent researches in moving object databases are attempting to achieve the support for movement information in DBMS. But the lack of support for handling such information is still an issue in current DBMSs, which becomes a barrier in processing and analyzing movement information. With the advancement of telemetry technology, where different devices are producing vast amount of movement data, the need of fulfilling this limitation is becoming bigger and bigger. This makes the research area of moving objects to become more important to deals with representation of these huge amount of data coming from different devices. This thesis project aims to provide a refined abstract and discrete design for the representation of moving point in current DBMS. The available models are reviewed and used as a starting point. First the abstract design is done followed by the discrete design. The discrete design paves the way for the implementation of the data type and operations on it, which can be used as an extension for DBMSs. Keywords Spatio-temporal, Databases, Moving objects, PostgreSQL, PostGIS
