Abstract

Aggregation is an important concept in database design where composite objects can be modelled during the design of database applications. Therefore, preserving the aggregation concept in database implementation is essential. In this paper, we propose models for implementation of aggregation in an Object-Relational Database Management System (ORDBMS) through the use of index clusters and nested tables. ORDBMS is a commercial Relational Database Management Systems (RDBMS), like Oracle, which support some object-oriented concepts. We will also show how queries can be performed on index clusters and nested tables.
