To illustrate the importance of "date desc," here are a few of the most recent DBA opportunities posted in early June 2026, showcasing a diverse range of requirements in a shifting market:

Note: Because the underlying view architecture pre-sorts records by date descending, a simple ROWNUM filter efficiently captures the latest changes without forcing a costly full-table sort at runtime. 2. Monitoring Invalid Objects from Recent Deployments
