....Our focus is on a uniform formalism used to represent different approaches. To illustrate our ideas, we propose a possible architecture for the object oriented query optimizer that was developed as a part of a COPERNICUS project [3] This query optimizer has been specified by the PRiSMLaboratory [6]. Optimization rules are described by using OFL (Object Functional Language) OFL is a target object language for OQLlike query compilers introduced in [9] OFL programs describe the traversals of collections in the execution world. In the traversal, functional predicate and projection expressions ....
