The architectural logic of database systems

de E. J. Yannakoudakis

This book describes and classifies all database languages and design methodologies, including normalization and canonical synthesis, and presents a complete glossary of the terminology of the subject. The languages discussed include DDL, DSDL, DML, IRDS, QBE, natural language and ISO standard languages RDL and NDL, which will provide a yardstick for comparative assessment for some years to come. This volume contains many examples, and avoids long introductions to various concepts. It is direct, factual, and describes "what it is", "how it works", and "how it can be applied". Written for those with an elementary knowledge of programming who require a general and up-to-date introduction to the logic behind a database, its architecture, and the various languages for defining, manipulating, and maintaining database records.
