Korth ebook pdf thnx for the book Female Branch: We will periodically update the page with supplementary material that may be of use to teachers and students. Internet electronic mail should be addressed to db-book-authors cs. These could include improved answers, additional questions, sample test ques- tions, programming projects, suggestions on alternative orders of presentation of the material, additional references, and so on.

All contributions that we make use of will, of course, be properly credited to their contributor.

This manual is derived from the manuals for the earlier edi- tions. John Corwin and Swathi Yadlapalli did the bulk of the work in preparing the instructors manual for the 5th edition.

Database System Concepts, 6th Edition

The manual for the 3th edition was prepared by K. Raghavan with help from Prateek R. The most important concept in this chapter is that database systems allow data to be treated at a high level of abstraction. Thus, the chapter motivates what the student will be studying in the rest of the course.

The idea of abstraction in database systems deserves emphasis throughout, not just in discussion of Section 1. The overview of the structure of databases is, of necessity, rather brief, and is meant only to give the student a rough idea of some of the concepts. The student may not initially be able to fully appreciate the concepts described here, but should be able to do so by the end of the course. These models can be used in Chapter 1 to reinforce the concept of abstraction, with syntactic details deferred to later in the course.

If students have already had a course in operating systems, it is worthwhile to point out how the OS and DBMS are related.

Exercises 1. Answer: Physical data independence is the ability to modify the physical scheme without making it necessary to rewrite application programs.

For each re- sponsibility, explain the problems that would arise if the responsibility were not discharged.

If these responsibilities were not met by a given DBMS and the text points out that sometimes a responsibility is omitted by design, such as concur- rency control on a single-user DBMS for a micro computer the following problems can occur, respectively: a. Unauthorized users may access the database, or users authorized to access part of the database may be able to access parts of the database for which they lack authority.

Data could be lost permanently, rather than at least being available in a consistent state that existed prior to a failure. Consistency constraints may be violated despite proper integrity en- forcement in each transaction.

Answer: a. Declarative languages are easier for programmers to learn and use and even more so for non-programmers. Updates to the building name and budget may get performed on some of the copies but not others, resulting in an inconsistent state where it is not clear what is the actual building name and budget of a department.

Ideally, we would like to have the department information in the database irrespective of whether the department has an associated instructor or not, without resorting to null values. Which is better suited for Web applications? Answer: In a two-tier application architecture, the application runs on the client machine, and directly communicates with the database system running on server.

The three-tier archicture is better suited for Web applications. Answer: Some possible tables are: a. A content table containing user provided content, such as text and images, associated with the user who uploaded the content. Exercises 5 c.

A friends table recording for each user which other users are connected to that user. The kind of connection may also be recorded in this table.

A permissions table, recording which category of friends are allowed to view which content uploaded by a user. For example, a user may share some photos with family but not with all friends.Then, would s id still be a primary key of the advisor relation?

These chapters also discuss variants supported by different database systems, to minimize problems that students face when they execute queries on actual database systems. Instructors covering the entire chapter will benefit from students having a good understanding of normalization concepts to motivate some of the challenging concepts of functional-dependency theory.

Korth S. Instructors are free to modify the slides to their taste, as long as the modified slides acknowledge the source and the fact that they have been modified. We have replaced the earlier running example of bank enterprise with a university example.

In addition, it may lead to data inconsistency; that is, the various copies of the same data may no longer agree.
