The purpose of this project is to investigate the suitability of the relational data model in preference to either the hierarchical data model or the network data model. The reason for considering the suitability of a relational database management system is the great flexibility in the way attributes and entities can be merged to produce new entities and structures. This flexibility might be utilized to access geographic information stored in a distributed environment
