Swan Lisa,Kupsco Jeremy,J. Robertmit the entity classes of the Functional Data Model to be viewed as Abstract Data Types to which methods stored in the modules can be applied. The database is stored as linked structures in a persistent heap. This architecture facilitates the use of Prolog as a navigational query language which can

https://doi.org/10.1385/1592598579ectly, an initial plan is first generated based upon a set of heuristic rules. Depending upon the application, the initial plan may be used either as the final plan or as a base in a subsequent search. A new concept — clustering degree of an index — is introduced to better model the I/O costs of ind
