<p>Systems EROS is a physical design tool for CODASYL database systems which covers a large spectrum of decision variables, notably location mode, set implementation, set order, and search keys. System EROS is based on a model where the CODASYL physical database design problem is formulated as an extension of the index selection problem in the relational database environment. Optimization algorithms for index selection are extended to solve the more complex problem of selecting a good physical access path configuration for CODASYL databases. The proposed approach represents a unified solution to the physical database design problem for both CODASYL and relational systems.</p>
