A database is a structured collection of data organized for efficient access, retrieval, and management. It typically consists of tables arranged in rows and columns. Each row is a unique record, and each column represents a specific attribute of that record. This organized structure enables the efficient handling of large data volumes, which is crucial in various applications, from business intelligence to web services.
Database Management Systems (DBMS)
A DBMS acts as a bridge between the database and its users. It provides multiple interfaces or APIs for data storage, retrieval, and manipulation. Key features of a DBMS include handling transactions, recovery, backups, concurrency, and ensuring security through authentication and authorization. It also maintains metadata catalogs and other functionalities essential for database operation and management.
