PL/SQL procedural language - Write stored procedures, functions, packages for complex business logic (Oracle banking systems process 100M+ transactions/day)

Oracle RAC (Real Application Clusters) - Achieve high availability and horizontal scalability with shared storage (eBay uses RAC for 99.99% uptime)

Advanced partitioning strategies - Range, list, hash, composite partitioning for massive tables (Telecom companies partition 10B+ CDR records)

Materialized views with query rewrite - Pre-compute aggregations for instant reporting (Oracle ERP systems use for financial dashboards)

ROWNUM vs ROW_NUMBER vs FETCH FIRST - Three different pagination approaches with performance trade-offs

Oracle optimizer and execution plans - Cost-based optimizer with 30+ years of refinement (consistently outperforms other databases on complex queries)
