A transformation from an object database to an object relational database

Abstract

Object Databases and object relational databases are both widely used in industries, The major differences are mainly the level of encapsulation and the language supported by individual DBMSs. Object databases are fully encapsulated and allowed only the use of methods to communicate with the objects. Object relational database, on the other hand allows the use of object-oriented SQL on open attributes. Both databases support the use of reference pointers and subtype hierarchies. Major software tools such as information warehouse software are now available commercially in the form of object relational representation. The purpose of this research project is to transform production-level systems on object database to object relational information warehouses.
