Object Oriented Database For A GIS

Abstract

This paper describes the design and implementation of geographic data in an object/relational database. Infomix Universal Server (IUS) is a tool that permits the description of persistent geographic objects. The geographic objects were designed by using the OMT methodology. The application was built with the Java programming language. The objects were made persistent by using the IUS database management system. A web user interface was developed to show the geographic data. Data modeling was done by using points, lines, polylines and polygons. The data stored in the database could be exported and used by a client who runs a web user interface. Our representation gives the description to have an homogeneous geographic data representation to be used in a geographic database server. The user can then access and use the data stored in the database.The web user interface runs on the client and the database manager runs on the server. The object oriented geographic databases that use a standard representation are the first step to build tools that will permit the interoperability of heterogeneous GIS.
