This book takes a fresh, pragmatic approach to database systems. With a strong design focus and using realistic case studies throughout, readers can master an accessible, step-by-step methodology, learn how to apply this to design and build applications, and gain a good understanding of the issues involved in building the systems.
Database Systems' practical, hands-on approach makes it uniquely suited to providing a strong foundation in good database design practice. A clear introduction to design, implementation and management issues, as well as an extensive treatment of database language and standards, make this book an indispensable complete reference for database students and professionals alike. The new edition of this bestseller brings it up to date with the latest developments in database technology and builds on the clear, accessible approach that contributed to the success of previous editions.
A realistic case study integrated throughout the book enables complex subjects to be explained in the context of one understandable example, while three additional case studies allow readers to work through examples by themselves. Clearly stated chapter objectives and summaries guide the reader, highlighted key definitions and numerous worked examples illustrate the concepts, and review questions and exercises reinforce the material covered in each chapter.
