We propose a two-pha.se algorithm for physical database design. In phase one the algorithm, for each logical query, losesrules to determine characteristics of a physical design (s...
We introduce a persistentfunctional languagecalled PFL which adapts functional programming to the area of deductive databases,much as logic-based deductive databaselanguagesadapt ...

In order to cope efficiently with simple or complex queries as well as different application requirements (e.g., ad-hoc versus repetitive queries), a query optimizer ought to supp...
Domain mismatch and schema mismatch are two of the important semantic integration problems for interoperating heterogeneous databases. This paper structures the domain mismatch pr...

: This paper presents database programming language constructs that. can be used to realize a variety of different semantics for rule application in active database syst.ems. The p...
