Recording
If you're talking about backing up data-files used in a company - it's a safety net in case something happens to their computer system. Businesses normally store back-ups 'off-site' so that, for example if there was a fire, the back-up files could be restored on a new computer, and the company wouldn't lose valuable data.
Database system can be defined as the collection of interrelated data. Uses of database system are that it maintains data security , data integrity, data can be easily accessed and shared too.
A sensible system for storage or filing of records should prioritize organization, accessibility, and security. Records should be categorized logically, using clear labels and consistent naming conventions to facilitate easy retrieval. Implementing a robust backup system is essential to prevent data loss, while access controls ensure that sensitive information is protected from unauthorized users. Regular audits and updates help maintain the integrity and relevance of the filing system over time.

* Defining the Schema The DBA defines the schema which contains the structure of the data in the application. The DBA determines what data needs to be present in the system ad how this data has to be represented and organized. * Liaising with Users The DBA needs to interact continuously with the users to understand the data in the system and its use. * Defining Security & Integrity Checks The DBA finds about the access restrictions to be defined and defines security checks accordingly. Data Integrity checks are also defined by the DBA. * Defining Backup / Recovery Procedures The DBA also defines procedures for backup and recovery. Defining backup procedures includes specifying what data is to backed up, the periodicity of taking backups and also the medium and storage place for the backup data. * Monitoring Performance The DBA has to continuously monitor the performance of the queries and take measures to optimize all the queries in the application.
