This curriculum spans the breadth of operational database administration as practiced in medium-to-large enterprises, comparable in scope to a multi-workshop technical enablement program for DBAs supporting business-critical applications across hybrid environments.

Module 1: Database Architecture and System Selection

  • Evaluate trade-offs between OLTP and OLAP systems when designing transactional versus analytical workloads.
  • Select appropriate database engines (e.g., PostgreSQL, Oracle, SQL Server) based on licensing costs, feature sets, and organizational compliance requirements.
  • Determine replication topology (master-slave, multi-master, or logical) based on application consistency and availability needs.
  • Assess the impact of schema design choices (normalized vs. denormalized) on query performance and maintenance complexity.
  • Integrate time-series or JSON-optimized databases (e.g., TimescaleDB, MongoDB) only when relational models introduce excessive overhead.
  • Plan for hybrid deployments involving both on-premises and cloud-managed databases, including latency and data sovereignty implications.
  • Define data sharding strategies based on access patterns, growth projections, and query routing capabilities.
  • Validate that chosen database platforms support required encryption-at-rest and encryption-in-transit standards.

Module 2: Installation, Configuration, and Environment Management

  • Standardize database installation procedures using infrastructure-as-code tools (e.g., Ansible, Terraform) to ensure consistency across environments.
  • Configure memory allocation (shared buffers, cache sizes) based on host RAM and expected workload concurrency.
  • Set up environment-specific parameter files (e.g., postgresql.conf, my.cnf) with appropriate logging, connection, and timeout settings.
  • Implement role-based access for administrative tasks during setup to prevent overprivileged service accounts.
  • Isolate development, testing, and production instances using network segmentation and access controls.
  • Automate configuration drift detection using monitoring tools to maintain compliance with baseline settings.
  • Configure timezone, locale, and collation settings during initialization to avoid data comparison issues later.
  • Document and version-control all configuration changes to support audit and rollback procedures.

Module 3: Security, Access Control, and Compliance

  • Enforce principle of least privilege by assigning database roles based on job function rather than granting broad admin rights.
  • Implement row-level security policies to restrict data access within shared schemas based on user context.
  • Rotate database credentials and API keys using automated secret management (e.g., HashiCorp Vault, AWS Secrets Manager).
  • Configure audit logging to capture login attempts, DDL changes, and sensitive data access for compliance reporting.
  • Apply database firewall rules to block known malicious IPs and restrict access to approved application servers only.
  • Mask sensitive data in non-production environments using dynamic data masking or anonymization scripts.
  • Validate that all connections use TLS 1.2+ and disable outdated protocols like SSLv3.
  • Conduct quarterly access reviews to deactivate orphaned or excessive user accounts.

Module 4: Backup, Recovery, and Disaster Planning

  • Define RPO and RTO targets in collaboration with business stakeholders and align backup frequency accordingly.
  • Implement full, differential, and transaction log backups in a tiered schedule based on data volatility.
  • Test point-in-time recovery procedures quarterly using production-like data sets to validate recovery scripts.
  • Store backups in geographically separate locations with immutable storage options to prevent ransomware corruption.
  • Encrypt backup files using customer-managed keys and verify decryption during recovery drills.
  • Automate backup validation by restoring to a sandbox environment and running checksum comparisons.
  • Document failover and failback procedures for primary database outages, including DNS and connection string updates.
  • Coordinate with storage teams to ensure snapshot consistency across multi-disk database volumes.

Module 5: Performance Monitoring and Query Optimization

  • Deploy real-time monitoring tools (e.g., Prometheus, Datadog) to track query latency, lock contention, and connection pool usage.
  • Analyze slow query logs to identify and refactor inefficient SQL statements with missing indexes or full table scans.
  • Use execution plans to evaluate index effectiveness and avoid over-indexing on low-selectivity columns.
  • Implement connection pooling (e.g., PgBouncer, HikariCP) to reduce overhead from frequent connection establishment.
  • Set thresholds for long-running queries and configure automatic alerts or cancellations.
  • Optimize batch operations using bulk insert methods and appropriate transaction boundaries.
  • Monitor temp space usage to detect queries generating excessive spool or sort files.
  • Coordinate with application teams to eliminate N+1 query patterns in ORM-generated SQL.

Module 6: High Availability and Failover Management

  • Configure automatic failover using witness servers or quorum-based clustering (e.g., Always On AG, Patroni).
  • Test failover scenarios during maintenance windows to validate switchover time and data consistency.
  • Implement health checks that monitor replication lag and trigger alerts before thresholds are breached.
  • Use load balancers with health-aware routing to direct traffic away from degraded or offline nodes.
  • Document manual intervention steps for failover when automated systems are unresponsive.
  • Ensure DNS and connection strings support dynamic endpoint resolution after failover.
  • Validate that standby nodes are configured with identical parameter settings to prevent post-failover issues.
  • Monitor split-brain risks in multi-datacenter setups and use fencing mechanisms to prevent dual primaries.

Module 7: Patching, Upgrades, and Lifecycle Management

  • Develop a version support matrix aligned with vendor end-of-life dates and internal risk tolerance.
  • Test patches and minor version upgrades in staging environments before deployment to production.
  • Plan maintenance windows for upgrades, considering application downtime and rollback procedures.
  • Use blue-green deployment patterns for major version upgrades to minimize service interruption.
  • Validate compatibility of third-party tools (backup, monitoring, ETL) after database upgrades.
  • Preserve deprecated features temporarily during migration but enforce deprecation timelines.
  • Document known issues and workarounds associated with specific patch levels.
  • Coordinate with application teams to update drivers and connection libraries in sync with DB changes.

Module 8: Integration with Application and DevOps Ecosystems

  • Standardize SQL linting and schema migration tools (e.g., Liquibase, Flyway) across development teams.
  • Enforce pre-deployment schema review gates in CI/CD pipelines to prevent unapproved DDL changes.
  • Integrate database monitoring alerts into central incident management platforms (e.g., PagerDuty, Opsgenie).
  • Share performance baselines with development teams to inform query design and indexing strategies.
  • Support feature flag implementations by designing schema extensions that do not block rollbacks.
  • Implement canary deployments for schema changes using dual-write patterns and shadow tables.
  • Provide production data subsets for testing using data subsetting tools while maintaining referential integrity.
  • Collaborate with SRE teams to align database SLOs with overall service reliability metrics.

Module 9: Capacity Planning and Cost Optimization

  • Forecast storage growth using historical trends and adjust auto-extension settings proactively.
  • Right-size database instances based on CPU, memory, and IOPS utilization over time.
  • Archive cold data to lower-cost storage tiers using partitioning and retention policies.
  • Negotiate reserved instance pricing for stable production workloads in cloud environments.
  • Identify and decommission unused databases or schemas to reduce licensing and maintenance overhead.
  • Monitor index bloat and vacuum efficiency to reclaim disk space and improve performance.
  • Use query cost analysis to identify high-resource operations and optimize or throttle as needed.
  • Report on per-application database resource consumption to inform chargeback or showback models.
