For database systems courses in Computer Science

 

This book introduces the fundamental concepts necessary for designing, using, and implementing database systems and database applications. Our presentation stresses the fundamentals of database modeling and design, the languages and models provided by the database management systems, and database system implementation techniques.

The book is meant to be used as a textbook for a one- or two-semester course in database systems at the junior, senior, or graduate level, and as a reference book. The goal is to provide an in-depth and up-to-date presentation of the most important aspects of database systems and applications, and related technologies. It is assumed that readers are familiar with elementary programming and data-structuring concepts and that they have had some exposure to the basics of computer organization.

STUDENT relation in Figure 07.01; we have t[Name] = <‘Barbara Benson’>, and t[SSN, GPA, Age] = <‘533-69-1238’, 3.25, 19>. 7.2 Relational Constraints and Relational Database Schemas 7.2.1 Domain Constraints 7.2.2 Key Constraints and Constraints on Null 7.2.3 Relational Databases and Relational Database Schemas 7.2.4 Entity Integrity, Referential Integrity, and Foreign Keys In this section, we discuss the various restrictions on data that can be specified on a relational database schema in the

sections they have completed; and the PREREQUISITE file stores the prerequisites of each course. To define this database, we must specify the structure of the records of each file by specifying the different types of data elements to be stored in each record. In Figure 01.02, each STUDENT record includes data to represent the student’s Name, StudentNumber, Class (freshman or 1, sophomore or 2, . . .), and Major (MATH, computer science or CS, . . .); each COURSE record includes data to represent

model. Chapter 4 describes additional data modeling concepts, such as generalization, specialization, and categories. Representational or implementation data models are the models used most frequently in traditional commercial DBMSs, and they include the widely-used relational data model, as well as the so-called 1 Page 39 of 893 legacy data models—the network and hierarchical models—that have been widely used in the past. Part II of this book is devoted to the relational data model, its

Library staff is divided into chief librarian, departmental associate librarians, reference librarians, check-out staff, and library assistants. Books can be checked out for 21 days. Members are allowed to have only five books out at a time. Members usually return books within three to four weeks. Most members know that they have one week of grace before a notice is sent to them, so they try to get the book

Calculate in msec the average time needed to search for an arbitrary record in the file, using linear search, if the file blocks are stored on consecutive disk blocks and double buffering is used. Calculate in msec the average time needed to search for an arbitrary record in the file, using linear search, if the file blocks are not
