Implementing effective database management practices involves monitoring database performance, optimizing query execution, and ensuring data integrity. Database administrators are responsible for identifying and resolving performance issues to maintain the best system operation. They also oversee data security measures to protect sensitive information from unauthorized access or breaches.

Security Measures

Security measures in database administration are essential for safeguarding sensitive information. Access control methods regulate who can view or manipulate data, ensuring only authorized individuals have the necessary permissions.

Data encryption techniques add another layer of protection by encoding data to prevent unauthorized access.

Access Control Methods

Access control methods play an essential role in safeguarding sensitive data and maintaining the integrity of a database system. Effective access control guarantees that only authorized users can interact with the database while preventing unauthorized access or modifications. Key methods for access control include:

User Authentication: Verifying the identity of users before granting access to the database.
Role-Based Permissions: Assigning permissions based on predefined roles to control what actions users can perform.
Access Control Lists (ACL): Specifying which users or systems are granted access privileges.
Biometric Access Control: Using unique biological traits for user verification.
