Database Management System: An Evolutionary Approach

Database management system (DBMS) is a collection of programs that enable users to create and maintain a database, it also consists of a collection of interrelated data and a set of programs to access that data. The DBMS is hence a general purpose software system that facilitates the processes of defining, constructing and manipulating databases for various applications.

The primary goal of a DBMS is to provide an environment that is both convenient and efficient to use in retrieving and storing data base information. It is an interface between the user of application programs on one hand and the data base on the other.

The objective of book Database Management System: An Evolutionary Approach is to enable learner:

• grasp basic understanding of DBMS, its need and terminologies.
• make a difference between the traditional file based systems and DBMS.
• to code while learn to grasp theory in practical way.
• with plenty of examples and case studies for better understanding.

This book Database Management System: An Evolutionary Approach is intended to give undergraduate and post graduate students a fundamental background in databases management system. The book follows an evolutionary learning approach that emphasize more on the basic concepts and build a strong foundation to learn more advanced topics like normalizations, Normal Forms, PL/SQL, Transactions, concurrency control, etc.

This book also gives the detailed knowledge with a focus on ER diagrams and its reductions in tables, with sufficient amount of SQL codes for more practical understanding.
