Database System Concepts, 5/e, is intended for a first course in databases at the junior or senior undergraduate, or first-year graduate, level. In addition to basic material for a first course, the text contains advanced material that can be used for course supplements, or as introductory material for an advanced course. The authors assume only a familiarity with basic data structures, computer organization, and a high-level programming language such as Java, C, or Pascal. Concepts are presented as intuitive descriptions, and many are based on the running example of a bank enterprise. 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. The fundamental concepts and algorithms covered in the book are often based on those used in existing commercial or experimental database systems. The aim is to present these concepts and algorithms in a general setting that is not tied to one particular database system. Details of particular commercial database systems are discussed in the case studies which constitute Part 8 of the book. The fifth edition of Database System Concepts retains the overall style of prior editions while evolving the content and organization to reflect the changes that are occurring in the way databases are designed, managed, and used. Key Handles: Early coverage of SQL in two chapters Think of SQL as doing or creating Queries Silberschatz uses a bank analogy throughout his text with Running Examples Case studies are incorporated that represent a different database, this is in the last Part of the text Focuses on cutting edge material, such as xml, web based database systems Salient Features New chapter organization, featuring earlier coverage of SQL. A new Part devoted to database design, with extended coverage of normalization and temporal data. Expanded and updated coverage of XML. Detailed coverage of database internals and architectures. Chapters on data mining and analysis and information retrieval. Case studies covering the latest versions of IBM DB2, Oracle, Microsoft SQL Server and (new to this edition) PostgresSQL. Emphasis on practical issues, applications and implementation, coupled with intuitive coverage of key theoretical concepts. Enhanced pedagogy. A web page (www.mhhe.com/silberschatz) featuring online solutions for practical exercises, detailed slides for all chapters, teaching supplements, and online appendices. Online appendices.
