A database is an organized collection of structured data that is stored and managed in a systematic manner. It is designed to efficiently store, retrieve, and manage large volumes of information. A database consists of tables or entities that represent different types of data, such as customers, products, or orders. Each table contains rows or records that represent individual instances of the data, and columns or fields that define the attributes or properties of the data. The purpose of a database is to provide a centralized and structured way to store and retrieve data, enabling efficient data management, querying, and analysis. It allows for data integrity, security, and scalability, supporting multiple concurrent users and applications. Databases are widely used in various domains, including business, finance, healthcare, e-commerce, and more. They serve as a critical foundation for storing and organizing data, providing a reliable and efficient way to manage and access information.
