SQL Developer Vs. Similar Roles
| Role | Main focus | Primary metric |
|---|---|---|
| SQL Developer | Writing and tuning queries, schemas, and stored procedures | Query performance, data accuracy |
| Database Administrator (DBA) | Keeping databases available, secure, and backed up | Uptime, recovery time |
| Data Analyst | Turning data into insights and reports | Insight accuracy, decisions supported |
