Abstract

• Objects can be many things varying from an actual feature which can be extracted from a scene to more abstract entities which are associated with those features. There are a variety of database structures which can be used to store data about spatial features. These include RDBMS (Relational Database Management Systems), OODBMS (Object Oriented Database Management Systems) and ORDBMS (Object Relational Database Management Systems). All of these have retrieval systems based on SL (Structured uery Language) and OL (Object uery Language). The aim of this research is to compare the storage structure, retrieving data of RDBMS, ORDBMS and OODBMS storing the GIS (Geographic Information System) data of some Yangon Regions townships. This research presents a study that investigates the current scope deployment of an effective and efficient geographical information system (GIS) based approach to the representation, organization and access of these databases by Yangon Region information.
