Inhaltsangabe

This book introduces a data manipulation system termed 'SYLLOG', a novel database system partly inspired by natural language processing and logic that enhances ease of use and simplicity. The author provides an in-depth examination of the history of data management systems, including their benefits and limitations, and presents the design and implementation of SYLLOG as a seamless language integrated into the database system. The author also presents theoretical results that establish the foundational correctness and capabilities of the system. The book finds its importance in the field of database systems by introducing a new approach to designing and implementing user-friendly and extensible database systems, and by providing theoretical results that justify the approach taken.

Excerpt from Syllog, a Knowledge Based Data Management System

Yet, substantial progress is being made in bringing techniques from logic into the realm of practical computation. In the programming language prolog a program is a set of ordered sequences of logical clauses. A clause can be a simple ground (variable-free) assertion, which can be regarded as a row in a relation in a data base, or it can be a conjunction of predicates containing variables which implies a conclusion predicate, in which case it can be regarded as a production rule. 80, for small data bases, prolog contains the means to store data, and to make deductions about the data using production rules.

There are two drawbacks to using prolog directly for a practical data base system. First, prolog notation, though natural for computer scientists, is probably difficult for most non-specialists to use. For example, an otherwise correct retrieval program, in which the order of two clauses is reversed, can enter an infinite loop. Second, the execution mechanism in current implementations is a depth first backtrack search over internal (or virtual) storage; the problem of efficiently searching external (e.g. Disk) storage has yet to be addressed.
