Promotional Information

This book is arranged in three parts and a set of appendixes:
* Preliminaries: Provides a detailed review of the relational model, and an overview of the Tutorial D language.
* Laying the Foundations: Explains basic temporal data problems and introduces fundamental constructs and operators for addressing those problems.
* Building on the Foundations: Applies the material of the previous part to issues of temporal database design, temporal constraints, temporal query and update, and much more.
* Appendixes: Include annotated references and bibliography, implementation considerations, and other topics.
Key features:
* Describes a truly relational approach to the temporal data problem.
* Addresses implementation as well as model issues.
* Covers recent research on new database design techniques, a new normal form, new relational operators, new update operators, a new approach to the problem of granularity, support for cyclic point types, and other matters.
* Includes review questions and exercises in every chapter.
* Suitable for both reference and tutorial purposes.
