What is a Database?
A database is a structured collection of data that is stored and managed electronically. It allows for efficient storage, retrieval, and manipulation of data. Databases are used in various applications, from small-scale personal projects to large-scale enterprise systems.
More specifically, Database is an organized collection of structured information, or data, that can be easily accessed, managed, and updated. It acts as a central digital repository, often managed by a Database Management System (DBMS), which is the software that interacts with users and applications, handling tasks like storing, retrieving, and modifying data without needing to know its physical location. Databases can be simple, like a physical address book, or complex, supporting large-scale operations for companies, websites, and apps.
