Database management has evolved from a specialized computer application to a central component of a modern computing environment, and, as a result, knowledge about database systems has become an essential part of an education in computer science.
This book is adapted from the seventh edition of Database System Concepts, for a first course in databases at the junior or senior undergraduate level. In this text, we present the fundamental concepts of database management. These concepts include aspects of database design, database languages, and database-system implementation. 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.
We assume only a familiarity with basic data structures, computer organization, and a high-level programming language such as Java, C, C , or Python. We present concepts as intuitive descriptions, many of which are based on our running example of a university. 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. Formal descriptions and proofs of theoretical results may be found in research papers and advanced texts that are referenced in the bibliographical notes.
The fundamental concepts and algorithms covered in the book are often based on those used in existing commercial or experimental database systems. Our aim is to present these concepts and algorithms in a general setting that is not tied to one particular database system.
In this adapted text of the seventh edition of Database System Concepts, we have retained essential contents of Database System Concepts, condensed or deleted some of the advanced materials. The purpose is to make this book more suitable for a first course in databases at the undergraduate level. Now we describe organization of this book in brief.
Content of This Book
The text is mainly organized in four parts.
Overview (Chapter 1). Chapter 1 provides a general overview of the nature and purpose of database systems. We explain how the concept of a database system has developed, what the common features of database systems are, what a database system does for the user, and how a database system interfaces with operating systems. We also introduce an example database application: a university organization consisting of multiple departments, instructors, students, and courses. This application is used as a running example throughout the book. This chapter is motivational, historical, and explanatory in nature.
Part 1: Relational Languages (Chapters 2 through 6). Chapter 2 introduces the relational model of data, covering basic concepts such as the structure of relational databases, database schemas, keys, schema diagrams, relational query languages, and relational operations. Chapters 3, 4, and 5 focus on the most influential of the user-oriented relational languages: SQL. Chapter 6 covers the formal relational query languages: relational algebra, tuple relational calculus, domain relational calculus, and Expressive Power of Pure Relational Query Languages.
The chapters in this part describe data manipulation: queries, updates, insertions, and deletions, assuming a schema design has been provided. Schema design issues are deferred to Part 2.
Part 2: Database Design and Application Development(Chapters 7 through 9). Chapter 7 provides an overview of the database-design process, with major emphasis on database design using the entity-relationship data model. The entity-relationship data model provides a high-level view of the issues in database design, and of the problems that we encounter in capturing the semantics of realistic applications within the constraints of a data model. UML class-diagram notation is also covered in this chapter.
Chapter 8 introduces relational database design. The theory of functional dependencies and normalization is covered, with emphasis on the motivation and intuitive understa
《数据库系统概念》是数据库系统方面的经典教材之一,其内容由浅入深,既包含数据库系统基本概念,又反映数据库技术新进展。本书基于该书第7版进行改编,保留其中的基本内容,压缩或删除了一些高级内容,更加适合作为国内高校计算机及相关专业本科生数据库双语课程教材。
