With current systems, some important complex queries may take days to complete because
of:(1) the volume of data to be processed,(2) limited aggregate resources. Introducing …

Linearization of nonlinear recursive programs is an important issue in logic databases for
both practical and theoretical reasons. If a nonlinear recursive program can be transformed …

Nonlinear recursive queries are usually less efficient in processing than linear recursive
queries. It is therefore of interest to transform non-linear recursive queries into linear ones …

Recently, a number of studies [Ull85, Ban86, Ban86a, Vie86, Boc86. Kri86, Kif86, Kif86a.
Loz85, Sac86, Agr87. Jag87a, Mac81, Van861 have concentrated on providing inferencing …

The problem of converting a simple nonlinear recursive logic query into an equivalent linear
one is considered. A general method is given to transform a nonlinear rule into a sequence …

We present a technique for integrating expert systems and database management systems
(DBMSs). Such integration is essential to accommodate new expert system applications that …

An extended version of our SIMD Relational Algebraic Processor is presented. In addition to
the usual relational and set operations the new machine has the ability to recycle its …

An arithmetic approach, such as the Level-Finding method described in this paper for
evaluating linear recursive queries in deductive database systems provides great potential …

The field of network management in modern telecommunications networks is discussed
along with the need for database and expert systems techniques in this field. It is pointed out …

The authors present a framework for optimization in coupling an expert system and a
database management system (DBMS) in such a way to satisfy the requirement of being …
