An Introduction to Data Base Design provides an understanding of how data base management systems (DBMS) work to be able to use any available commercial DBMS intelligently. This book presents the principle of independence of physical and local organization. Organized into seven chapters, this book begins with an overview of normal form theory. This text then describes the three types of DBMS. Other chapters consider the difficulties in processing queries where the names of the files are not mentioned. This book discusses as well how to group data hierarchically, how to use a preorder tree traversal to represent the data, and how to convert a network organization to a hierarchical one. The final chapter deals with four essential issues in data base theory, namely, recovery, security, integrity, and concurrency. This book is a valuable resource for computer science students in the junior or senior year, and people in industry who are doing technical work using data bases.A prime attribute is one that is in some key; a non-prime attribute is in no key. Let us recall the first example from this chapter, transformed into first normal form. We had a record type with ... Check out each attribute A which is in no key (i.e.anbsp;...
