Finally, Chapter 23 focuses on database recovery protocols, and gives an overview of the concepts and techniques that are used in recovery. Part 10 Chapters 23, 24, and 25 includes the chapter on distributed data- bases Chapter 23 , plus the two new chapters on NOSQL storage systems for big data Chapter 24 and big data technologies based on Hadoop and MapReduce Chapter Chapter 23 introduces distributed database concepts, including availability and scalability, replication and fragmenta- tion of data, maintaining data consistency among replicas, and many other concepts and techniques.

Chapter 27 discusses information retrieval IR and Web search, and includes topics such as IR and keyword-based search, comparing DB with IR, retrieval models, search evaluation, and ranking algorithms. Chapter 28 is an introduction to data mining including over- views of various data mining methods such as associate rule mining, cluster- ing, classification, and sequential pattern discovery. Chapter 29 is an overview of data warehousing including topics such as data warehousing models and operations, and the process of building a data warehouse.

Part 12 Chapter 30 includes one chapter on database security, which includes a discussion of SQL commands for discretionary access control GRANT, REVOKE , as well as mandatory security levels and models for including mandatory access control in relational databases, and a discussion of threats such as SQL injection attacks, as well as other techniques and methods related to data security and privacy. These may be substituted for the notation we use, if the instructor prefers.

Appendix B gives some important physical parameters of disks. They have been used for more than thirty years as a basis for many commercial database applications and transaction- processing systems. There are many different ways to teach a database course. The chapters in Parts 1 through 7 can be used in an introductory course on database systems in the order that they are given or in the preferred order of individual instructors.

Selected chap- ters and sections may be left out and the instructor can add other chapters from the rest of the book, depending on the emphasis of the course. We suggest covering up to Chapter 15 in an introductory database course and including selected parts of other chapters, depending on the background of the students and the desired coverage.

For an emphasis on system implementation techniques, chapters from Parts 7, 8, and 9 should replace some of the earlier chapters. Chapters 3 and 4, which cover conceptual modeling using the ER and EER models, are important for a good conceptual understanding of databases. However, they may be partially covered, covered later in a course, or even left out if the emphasis is on DBMS implementation. Chapters 16 and 17 on file organizations and indexing may also be covered early, later, or even left out if the emphasis is on database mod- els and languages.

For students who have completed a course on file organization, parts of these chapters can be assigned as reading material or some exercises can be assigned as a review for these concepts. If the emphasis of a course is on database design, then the instructor should cover Chapters 3 and 4 early on, followed by the presentation of relational databases.

A total life-cycle database design and implementation project would cover conceptual design Chapters 3 and 4 , relational databases Chapters 5, 6, and 7 , data model mapping Chapter 9 , normalization Chapter 14 , and application programs implementation with SQL Chapter Chapter 11 also should be covered if the emphasis is on Web database programming and applications.

The book is written so that it is possible to cover topics in various sequences. The following chapter dependency chart shows the major dependencies among chap- ters. As the diagram illustrates, it is possible to start with several different topics following the first two introductory chapters. Although the chart may seem com- plex, it is important to note that if the chapters are covered in order, the dependen- cies are not lost.

The chart can be consulted by instructors wishing to use an alternative order of presentation. For a one-semester course based on this book, selected chapters can be assigned as reading material. The book also can be used for a two-semester course sequence. The first course, Introduction to Database Design and Database Systems, at the sophomore, junior, or senior level, can cover most of Chapters 1 through The second course, Database Models and Implementation Techniques, at the senior or first-year graduate level, can cover most of Chapters 16 through The two- semester sequence can also be designed in various other ways, depending on the preferences of the instructors.

Author : M. This third edition of a classic textbook can be used to teach at the senior undergraduate and graduate levels. The material concentrates on fundamental theories as well as techniques and algorithms. The advent of the Internet and the World Wide Web, and, more recently, the emergence of cloud computing and streaming data applications, has forced a renewal of interest in distributed and parallel data management, while, at the same time, requiring a rethinking of some of the traditional techniques.

This book covers the breadth and depth of this re-emerging field. The coverage consists of two parts. The first part discusses the fundamental principles of distributed data management and includes distribution design, data integration, distributed query processing and optimization, distributed transaction management, and replication.

The second part focuses on more advanced topics and includes discussion of parallel database systems, distributed object management, peer-to-peer data management, web data management, data stream systems, and cloud computing. This product is a complete reference to both classical material and advanced topics that are otherwise scattered in sometimes hard-to-find papers. A major effort in writing the book was made to highlight the intuitions behind the theoretical development.

Clear explanations of theory and design, broad coverage of models and real systems, and an up-to-date introduction to modern database technologies result in a leading introduction to database systems. Intended for computer science majors, this text emphasizes math models, design issues, relational algebra, and relational calculus. A lab manual and problems give students opportunities to practice the fundamentals of design and implementation. Real-world examples serve as engaging, practical illustrations of database concepts.

The Sixth Edition maintains its coverage of the most popular database topics, including SQL, security, and data mining, and features increased emphasis on XML and semi-structured data. This is the eBook of the printed book and may not include any media, website access codes, or print supplements that may come packaged with the bound book.

A basic understanding of algebraic expressions and laws, logic, basic data structure, OOP concepts, and programming environments is implied. Written by well-known computer scientists, this introduction to database systems offers a comprehensive approach, focusing on database design, database use, and implementation of database applications and database management systems. The first half of the book provides in-depth coverage of databases from the point of view of the database designer, user, and application programmer.

The second half of the book provides in-depth coverage of databases from the point of view of the DBMS implementor. It focuses on storage structures, query processing, and transaction management.

The book covers the main techniques in these areas with broader coverage of query optimization than most other texts, along with advanced topics including multidimensional and bitmap indexes, distributed transactions, and information integration techniques. Much more than a study guide, this edition helps those who have only a basic knowledge of databases master the latest SQL and Oracle concepts and techniques.

This edition initially focuses on creating database objects, including tables, constraints, indexes, sequences, and more. The author then explores data query techniques, such as row filtering, joins, single-row functions, aggregate functions, subqueries, and views, as well as advanced query topics.
