Database System Concepts by Silberschatz, Korth and Sudarshan is now in its 7th edition and is one of the cornerstone texts of database education. It presents the fundamental concepts of database management in an intuitive manner geared toward allowing students to begin working with databases as quickly as possible.

The text is designed for a first course in databases at the junior/senior undergraduate level or the first year graduate level. It also contains additional material that can be used as supplements or as introductory material for an advanced course. Because the authors present concepts as intuitive descriptions, a familiarity with basic data structures, computer organization, and a high-level programming language are the only prerequisites. Important theoretical results are covered, but formal proofs are omitted. In place of proofs, figures and examples are used to suggest why a result is true.

Henry F. (Hank) Korth is a Professor of Computer Science and Engineering and co-director of the Computer Science and Business program at Lehigh University. Prior to joining Lehigh, he was director of Database Principles Research at Bell Labs, a vice president of Panasonic Technologies, an associate professor at the University of Texas at Austin, and a research staff member at IBM Research. Korth is a fellow of the ACM and of the IEEE and a winner of the 10-Year Award at the VLDB Conference. His numerous research publications span a wide range of aspects of database systems, including transaction management in parallel and distributed systems, real-time systems, query processing, and the influence on these areas from modern computing architectures. Most recently, his research has addressed issues in the application of blockchains in enterprise databases.
