A database is an organized collection of data that is stored and managed in a structured manner. It is designed to efficiently store, retrieve, and manage large amounts of data. A database management system (DBMS) is a software application that enables users to create, manipulate, and access databases.
Databases are used in a variety of applications such as banking systems, e-commerce websites, healthcare systems, social media platforms, and many more. They are essential for managing and organizing data, which helps businesses and organizations make informed decisions based on the insights derived from the data.
Databases can be classified based on the type of data they store, the number of users accessing the data, the structure of the data, and the mode of access. The most common types of databases include relational databases, NoSQL databases, hierarchical databases, and object-oriented databases.
