Author Description

This text is intended to provide a greater depth of coverage of data languages than is currently available. These languages have been colloquially called "fourth generation languages" available in a large number of commercial products. The book is structured around the basic principles that tend to be common to the majority of these products. Relational database theory, along with relational languages and their various commercial implementations, visual programming and integrated programming environments are covered in some depth. This book is intended for business students who have had at least one course in a traditional programming language (COBOL, BASIC, etc.) without any other prerequisites.
