An Indexing Technique for Object-Oriented Databases

We present an indexing technique providing efficient support for object-oriented queries. We first briefly discuss object-oriented query languages. Then, we describe the indexing technique and the associated operations. A preliminary comparison of our technique with previously defined access mechanisms is also presented.

Function-based indexing for object-oriented databases

Object-oriented databases have been developed to allow applications to store persistent data in the form of objects. As in conventional databases, object-oriented databases need to support queries that allow associative access to data by describing a property of the data of interest. In particular, they should support queries over user-de ned sets based on user-de ned functions that compute the...
