About This Book
Database Management Systems (DBMS) are software systems designed to manage databases and
provide an interface for users and applications to interact with data. The core function of a DBMS is to
store, retrieve, and manage data efficiently, while ensuring data integrity, security, and consistency.
DBMSs use a structured approach to store data, which is typically organized in tables, rows, and columns.
A Relational Database Management System (RDBMS) is the most common type of DBMS, where data is
organized in relational tables and can be queried using Structured Query Language (SQL). These systems
support relationships between different data tables and enforce referential integrity constraints,
ensuring that data remains accurate and consistent. DBMSs provide various functionalities, including
data definition, data manipulation, and data control. Data definition involves creating and modifying the
structure of the database, while data manipulation enables querying and updating the data. Data control
ensures that users can only access data according to predefined access permissions. In modern
applications, DBMSs support various types of databases, including distributed databases, NoSQL
databases, and graph databases, catering to specific needs like scalability, speed, and flexibility.
Additionally, DBMSs play a critical role in transaction management and recovery, ensuring that the
database remains in a consistent state even after system failures. Database Management Systems
provides a comprehensive guide to understanding the architecture, components, and practical
applications of database systems in modern computing.
