The role of a Database Administrator (DBA) is vital in managing an organization’s data resources. According to Chapter 15 of the IGU Online Library, the DBA's core functions include designing, implementing, maintaining, and securing databases. They are responsible for ensuring data accuracy, integrity, and accessibility while optimizing database performance. The DBA must also enforce security policies to prevent unauthorized access and ensure compliance with data regulations. Additionally, the DBA handles backup and recovery procedures to safeguard data against data loss or corruption. They continuously monitor database performance, update software, and implement changes to support organizational needs. These responsibilities are crucial for maintaining data consistency, security, and operational efficiency within an enterprise.

Security of data and information fundamentally relies on the CIA triad—Confidentiality, Integrity, and Availability. Confidentiality ensures that sensitive data is accessed only by authorized individuals. For example, personal customer data stored in a database is protected through encryption and access controls to prevent unauthorized viewing. Integrity guarantees that data remains accurate and unaltered during storage and transmission. An example of integrity is implementing checksums or digital signatures to verify that data has not been tampered with during transfer. Availability assures that data is accessible when needed by authorized users. For instance, using redundant servers and reliable backups ensures that data remains accessible even during failures or cyber-attacks. These three components form the foundation of a secure data management system, with CIA representing the minimum security standards that organizations must meet to protect their digital assets effectively.
