Database systems underlie the large majority of business information systems. 10 Relational Database Relational Database Management System (RDBMS) consists of: – A set of tables – A schema A schema: – is a description of data in terms of data model – Defines tables and their attributes (field or column) The central data description construct is a relation: – Can be thought as records – eg. information on student is stored in a relation with DesignGoals: zAvoid redundant data zEnsure that relationships among attributes are represented zFacilitate the checking of updates for violation of database Typical relational database design examples in textbooks and undergraduate courses are small and do not provide any real opportunity to practice the design, they simply illustrate and illuminate the principles. Design of a database, like all design problems, is a matter of business needs and judgment. A bad design may lead to zRepetition of Information. 3.Provide three examples of a real-world database (e.g., the library contains a database of books). Database design •Understand the real-world domain being modeled •Specify it using a database design model Book description. In an example to follow, we shall expand our application of a registrar’s database involving courses, and thereby expose some of the principles of good database design.

This text is a free introductory text that introduces MS Access and relational database design. The final two chapters address various issues in relational database design. Chapter 7, Database Design I: Projection-Join Normalization, based on lectures 8 and 9, deals with one particularly important issue that has been the subject of much research over the years. The motivation is to support a second-year course on database systems which, to the student, is either a service course providing an introduction to database concepts, or, as a prerequisite for more advanced study in the field. Pitfalls in Relational Database Design Relational database design requires that we find a “good” collection of relation schemas.
