In the context of the CompTIA DataSys+ certification, Database Management and Maintenance is a critical domain that focuses on the ongoing operational health, stability, and efficiency of database systems after their initial deployment. This area encompasses a wide array of administrative tasks designed to ensure data availability, integrity, and security. A primary responsibility is performance monitoring and tuning, where administrators must continuously track system metrics like CPU usage, memory consumption, and disk I/O to identify bottlenecks. This involves analyzing slow-running queries, optimizing execution plans, and managing indexes—deciding when to rebuild or reorganize them to reduce fragmentation.
Storage management is equally vital, requiring proactive capacity planning to manage table spaces and transaction logs to prevent space exhaustion. Administrators must also establish and verify robust backup and recovery strategies, utilizing full, differential, and transaction log backups to meet specific Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO). The curriculum emphasizes that backups are only effective if restoration procedures are frequently tested.
Security maintenance involves applying the latest patches and updates to the Database Management System (DBMS) to mitigate vulnerabilities, as well as auditing user access and enforcing the principle of least privilege. Furthermore, automation is a key skill, requiring the scheduling of routine jobs—such as database consistency checks and statistics updates—to minimize manual intervention and human error. High availability configurations and disaster recovery planning also fall under this scope, ensuring business continuity in the event of hardware failure or corruption. Ultimately, effective management and maintenance ensure the database reliably adheres to Service Level Agreements (SLAs) throughout its lifecycle.In the context of the CompTIA DataSys+ certification, Database Management and Maintenance is a critical domain that focuses on the ongoing operational health, stability, and efficiency of database systems after their initial deployment.
