Book Description
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.

A database refers to systematic collection of data which is stored and can be accessed electronically. The software system that allows users to create, define and maintain this database is known as database management system. It collectively defines database, database model and database management system. It is used to manage internal operations of organizations and determine online interactions with suppliers and customers. They are categorized on the basis of the database model they support, the types of systems they run on, the language used to access it and on their internal engineering. The different types of databases are in-memory database, cloud database, deductive database, document-oriented database, federated database system, active database and data warehouses. Database systems are used in areas such as flight reservation systems, content management systems, library systems and computerized parts inventory systems.
