Abstract

Optimising access to data returned by methods is an important issue in object–oriented programs, databases, and distributed object environments. Since methods are written in a high–level programming language, optimising their executions is a serious problem. In this paper we present our technique of reducing access time to data returned by methods by means of the hierarchical materialization that we developed. In this technique, the materialisation of method m results also in the materialisation of intermediate results of methods called from m. Moreover, we present data structures and evaluation of two optimisation techniques that allow to query results returned by methods.
