Database Management System (DBMS)

A DBMS is a software system designed to manage data. It allows users to store, retrieve, and manipulate data in various forms such as text, numbers, images, and so on. Oracle is a comprehensive DBMS that can manage large volumes of data.

Rollback segments are used to store data changes that may need to be undone. They are used to ensure that the database remains consistent in the event of a rollback.

Backup and Recovery

Backup and recovery refer to the process of creating backups of the database and restoring it to a previous state. This process is essential for maintaining the integrity and availability of data.

Data Integrity

Data integrity refers to the accuracy, completeness, and consistency of data. Database constraints such as primary keys, unique constraints, and foreign keys help ensure data integrity.

1 Performance Tuning

Performance tuning refers to the process of optimizing the database’s performance. This involves identifying and resolving performance bottlenecks to improve the database’s responsiveness.
