INTRODUCTION TO DATABASE MANAGEMENT SYSTEM ,APPLICATION AND ADVABTAGES
A Database Management System (DBMS) is software that enables users to interact with a database. A database is a structured collection of data that is organized and stored in a way that allows for efficient retrieval, management, and manipulation of the data. DBMS provides an interface for users and applications to interact with the database, ensuring data integrity, security, and efficient management.
Applications of DBMS:
Databases help minimize data redundancy by storing data in a centralized manner, where each piece of data is stored only once. This reduces the unnecessary duplication of data across different systems and applications, ensuring consistency and saving storage space.
Databases ensure data integrity by enforcing rules and constraints on the data, such as primary keys, foreign keys, and unique constraints. This guarantees that the data remains accurate, consistent, and reliable over time.
Advanced DBMSs provide robust security features to protect data from unauthorized access and breaches. This includes user authentication, access controls, encryption, and auditing capabilities to monitor and manage who accesses and manipulates the data.
By maintaining a single source of truth, databases ensure that all users and applications see a consistent view of the data. This consistency is critical for making accurate business decisions and running reliable applications.
Databases allow multiple users to access and manipulate data simultaneously, facilitating data sharing across departments and applications. This promotes collaboration and ensures that everyone in the organization is working with up-to-date information.
