| 1.3 | Normalization & Relational Theory: Design a database schema that adheres to **Third Normal Form (3NF)** and articulate *why* denormalization is sometimes needed for analytics. | |
| 1.4 | Stored Procedures/Functions: Write and execute complex stored procedures, triggers, or functions to automate common administrative tasks. | |

2. Performance & Maintenance
| Step | Action Item | Status |
|---|---|---|
| 2.1 | Indexing Strategies: Apply different types of indexes (clustered, non-clustered, composite) to tables and measure the resulting query speed improvement. | |
| 2.2 | Query Optimization: Learn to use the `EXPLAIN PLAN` (or equivalent) feature in your database to identify and fix bottlenecks in slow queries. (Crucial) | |
| 2.3 | Backup & Recovery: Implement a full backup, differential backup, and point-in-time recovery for a test database to understand recovery models. | |
| 2.4 | Monitoring Basics: Set up a basic monitoring dashboard (e.g., using OS tools or database-specific utilities) to track CPU usage, memory, and disk I/O. | |
| 2.5 | Cloud-Managed Services: Understand the benefits and differences of using managed database services (RDS, Azure SQL Database, Cloud SQL) versus self-hosted installations. |
3. Professional Development & Portfolio

| 3.3 | Focus on One Vendor Certification: Select an entry-level certification path (e.g., Oracle Certified Associate, Microsoft Certified: Azure Database Administrator Associate) and begin studying. | |
| 3.4 | Update Resume Keywords: Use terms like T-SQL/PL/pgSQL, Indexing, Database Security, Backup and Recovery, and Performance Tuning. | |
| 3.5 | Explain High Availability (HA): Understand and explain the basic principles of HA, such as replication, failover, and clustering, to secure business continuity. |
