A database is a collection of logically connected information that is arranged in such a way that it can be easily accessed, controlled, and updated. Databases are often accessible electronically via a computer system and managed by a Database Management System (DBMS). The database administrator (DBA) is the person in charge of database management, which includes database security, access control, backup, and disaster recovery.
A database is a collection of logically connected information that is arranged in such a way that it can be easily accessed, controlled, and updated. Databases are often accessible electronically via a computer system and managed by a Database Management System (DBMS). Internal and external databases are commonly used by businesses. Internal databases are commonly comprised of operational databases and data warehouses. External databases are databases that are not held by an organisation and are generally accessed through the Internet. A database's five major components are hardware, software, data, procedures, and database access language.
