This book is primarily intended for use as a text in a database management course that approaches the subject as a business application. It can also be the basis for a short, intensive relational database design seminar. Features: * The first part of the text focuses on design of relational databases, from how systems work to maximising relational design. * Chapter 2 reviews the systems development cycle for students who have not recently studied systems analysis and design. * The second portion of the text focuses on data manipulation, including relational algebra, QBE, interactive SQL, and database integrity. * The final portion of the text presents the main issues of multiuser databases and data management. * Examples in the book involve two case studies: Small Bank, and Federated Taxi Company. Two additional case studies form the basis for end-of-chapter exercises. * End-of-chapter discussion questions and exercises encourage students to view concepts in different contexts and give practice in assessing user needs, formulating good relational designs, and creating effective queries.
Introduces the Computer Novice to the Nature & Use of Databases. Explains the Major Types of Data Storage & Access
Description & Guide to the Use of Database Management Systems on Microcomputers
Presented in nonmathematical terms, this book prepares the reader to design, implement, and query a relational database. Jackson discusses both the entity-relationship method and functional dependencies, and defines relevant terms. He illustrates the problems related to redundant functional dependencies, and points out the pitfalls in design and implementation. He also presents a case study involving a bowling league. Jackson describes the problem, identifies attributes, constructs the universal relation, moves the redundancies, and decomposes the relation into four relations. He also implements the case study database in both dBASE III and R:base 5000. The techniques developed here are useful not only for systems created for microcomputers but other database management systems also. ISBN 0-13-771841-1: $20.00.
