Abstract
Object-relational data warehousing systems are more and more often applied to the integration and analysis of complex data. For such warehouses, the application of materialized object-oriented views is promising. Such views are able to: (1) integrate not only data of complex structure but also manage the behavior of data, i.e. methods, (2) transform simple relational data to data of complex structure and vice versa. This paper addresses a materialization technique of method results in object-oriented views. We have developed methods’ materialization technique, so called hierarchical materialization, and evaluated this technique by a number of experiments concerning methods without input arguments as well as methods with input arguments, for various patterns of method dependencies. The obtained results show that the hierarchical materialization may significantly reduce methods’ execution times. In this paper we present the results concerning methods without input arguments.
