This book introduces the fundamental concepts nec-essary for designing, using, and implementing
database systems and database applications. Our presentation stresses the funda-mentals of database modeling and design, the languages and models provided by
the database management systems, and database system implementation tech-niques. The book is meant to be used as a textbook for a one- or two-semester
course in database systems at the junior, senior, or graduate level, and as a reference
book. Our goal is to provide an in-depth and up-to-date presentation of the most
important aspects of database systems and applications, and related technologies.
We assume that readers are familiar with elementary programming and data-structuring concepts and that they have had some exposure to the basics of com-puter organization
