An Introduction to Database System

<p>A 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. Hence a DBMS is a general-purpose software system that facilitates the processes of defining constructing and manipulating databases for various applications.</p><p>The primary goal of a DBMS is to provide an environment that is both convenient and efficient to use in retrieving and storing database information. It is an interface between the user of application programs on the one hand and the database on the other.</p><p>The objective of Database Management System: An Evolutionary Approach is to enable the learner to Grasp a basic understanding of a DBMS its need and its terminologiesdiscern the difference between the traditional file-based systems and a DBMScode while learning to grasp theory in a practical way to study provided examples and case studies for better comprehension.</p><p>This book is intended to give under- and postgraduate students a fundamental background in DBMSs. The book follows an evolutionary learning approach that emphasizes the basic concepts and builds a strong foundation to learn more advanced topics including normalizations normal forms PL/SQL transactions concurrency control etc.</p>
