Abstract

Corollary to the development of new kinds of application - like decision support ones - manipulating large quantities of data structured in new kinds of data supports -like data warehouses, queries formulated to access this data have been growing in their complexity. However, with the exception of approaches facilitating syntax problems, there is a noticeable absence of models taking charge of the user through from specification of their needs to formulation of their queries. In the case of object-oriented database systems, whose data models and concepts are more complex than those of relational databases, database users need assistance with several kind of formulation problems. In this article, we take a novel look at object-oriented queries - reifying the ones which users formulate as components then reusing them, by means of strategies for selecting, assembling and adapting them to help in the formulation of new complex queries.
