Integrated Deductive Database System Implementation: A Systematic Study

DES: A Deductive Database System

This work describes a novel implementation of a deductive database system which fills some gaps other systems do not. In fact, this system was born to this end and since its inception, many new features have been added (null values, outer joins, aggregates, ...). In particular, it embodies both Datalog and SQL query languages, where the same database can be queried. It enjoys an actual interact...

Design and Implementation of the Relationlog Deductive Database System

We describe the design and implementation of Relationlog, a persistent deductive database system. Unlike other related systems such as Aditi, CORAL, LDL, LOLA and Nail-Glue, Relationlog supports effective storage, efficient access and inference of large amounts of data with complex structures and provides declarative query language that can define recursive views involving complex data and also...

The MyYapDB Deductive Database System

We describe the MyYapDB, a deductive database system coupling the Yap Prolog compiler and the MySQL DBMS. We use our OPTYap extension of the Yap compiler, which is the first available system that can exploit parallelism from tabled logic programs. We describe the major features of the system, give a simplified description of the implementation and present a performance comparison of using stati...
