Duration 5 Days – 35–40 hours
Overview
This training provides a practical foundation in database administration and management, covering the essential responsibilities of a DBA—from installation and configuration to user access control, backup and recovery, performance tuning, monitoring, and basic troubleshooting. Participants will learn how to manage databases reliably in both on-premise and cloud environments while applying industry best practices for security, availability, and operational stability.
Objectives
- Understand DBA roles, database architecture, and key operational responsibilities
- Install and configure a database environment using best practices
- Create and manage users, roles, permissions, and database security controls
- Perform routine DBA tasks including maintenance, monitoring, and housekeeping
- Implement reliable backup and recovery strategies (including disaster recovery basics)
- Optimize performance using indexing, query tuning, and resource monitoring
- Troubleshoot common database issues (locks, slow queries, storage, errors)
- Apply operational discipline using documentation, checklists, and standard procedures
Target Audience
- Junior / Aspiring Database Administrators (DBAs)
- System Administrators managing database servers
- Application Support / Production Support Engineers
