Part 3 Chapters 5 through 8 includes a detailed presentation on relational databases and SQL with some additional new material in the SQL chapters to cover a few SQL constructs that were not in the previous edition. Chapter 5. Chapter 6 describes some of the basic parts of the SQL standard for relational databases, including data definition, data modification opera- tions, and simple SQL queries. Chapter 7 presents more complex SQL que- ries, as well as the SQL concepts of triggers, assertions, views, and schema modification.

Chapter 8 describes the formal operations of the relational algebra and introduces the relational calculus. The material on SQL Chap- ters 6 and 7 is presented before our presentation on relational algebra and calculus in Chapter 8 to allow instructors to start SQL projects early in a course if they wish it is possible to cover Chapter 8 before Chapters 6 and 7 if the instructor desires this order.

Part 4 Chapters 10 and 11 are the chapters on database programming tech- niques; these chapters can be assigned as reading materials and augmented with materials on the particular language used in the course for program- ming projects much of this documentation is readily available on the Web.

Chapter 11 introduces Web database programming, using the PHP scripting language in our exam- ples, and includes new material that discusses Java technologies for Web database programming. Part 5 Chapters 12 and 13 covers the updated material on object-relational and object-oriented databases Chapter 12 and XML Chapter 13 ; both of these chapters now include a presentation of how the SQL standard incorpo- rates object concepts and XML concepts into more recent versions of the SQL standard.

Chapter 12 first introduces the concepts for object databases, and then shows how they have been incorporated into the SQL standard in order to add object capabilities to relational database systems. It then covers the ODMG object model standard, and its object definition and query lan- guages.

Part 6 Chapters 14 and 15 are the normalization and relational design theory chapters we moved all the formal aspects of normalization algo- rithms to Chapter Chapter 14 defines functional dependencies, and the normal forms that are based on functional dependencies.

Chapter 14 also develops a step-by-step intuitive normalization approach, and includes the definitions of multivalued dependencies and join dependencies. Part 7 Chapters 16 and 17 contains the chapters on file organizations on disk Chapter 16 and indexing of database files Chapter Chapter 16 describes primary methods of organizing files of records on disk, including ordered sorted , unordered heap , and hashed files; both static and dynamic hashing techniques for disk files are covered.

Chapter 16 has been updated to include materials on buffer management strategies for DBMSs as well as an overview of new storage devices and standards for files and mod- ern storage architectures.

Chapter 17 describes indexing techniques for files,. Part 8 Chapters 18 and 19 includes the chapters on query processing algo- rithms Chapter 18 and optimization techniques Chapter 19 ; these two chapters have been updated and reorganized from the single chapter that covered both topics in the previous editions and include some of the newer techniques that are used in commercial DBMSs.

Chapter 18 presents algo- rithms for searching for records on disk files, and for joining records from two files tables , as well as for other relational operations. Chapter 18 con- tains new material, including a discussion of the semi-join and anti-join operations with examples of how they are used in query processing, as well as a discussion of techniques for selectivity estimation. Chapter 19 covers techniques for query optimization using cost estimation and heuristic rules; it includes new material on nested subquery optimization, use of histograms, physical optimization, and join ordering methods and optimization of typical queries in data warehouses.

Part 9 Chapters 20, 21, and 22 covers transaction processing concepts; concurrency control; and database recovery from failures. These chapters have been updated to include some of the newer techniques that are used in some commercial and open source DBMSs.

Chapter 20 introduces the techniques needed for transaction processing systems, and defines the concepts of recoverability and serializability of schedules; it has a new sec- tion on buffer replacement policies for DBMSs and a new discussion on the concept of snapshot isolation.

Chapter 21 gives an overview of the var- ious types of concurrency control protocols, with a focus on two-phase locking. We also discuss timestamp ordering and optimistic concurrency control techniques, as well as multiple-granularity locking.

Chapter 21 includes a new presentation of concurrency control methods that are based on the snapshot isolation concept. 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. Do you like this book? Please share with your friends, let's read it!! Search Ebook here:.
