Learning Oracle as a SQL Server expert presents challenges due to fundamental differences in architecture, terminology, and performance tuning. This session demystifies Oracle for SQL Server professionals by bridging conceptual gaps and providing a deep dive into Oracle internals and optimization techniques.

Key areas covered:

Architecture Differences: Understanding Oracle's multiple architectures, redo/undo mechanisms, and storage structures compared to SQL Server’s transaction log and tempdb.

Terminology Confusion: Mapping SQL Server concepts (e.g., databases, schemas, isolation levels) to their Oracle equivalents to eliminate common misconceptions.

Performance Tuning: Exploring Oracle’s optimizer, Automatic Workload Repository/Active Session History, execution plans, indexing strategies, and plan management.

Administrative Nuances: Key differences in backup, recovery, high availability, and management practices.

By the end of this session, SQL Server experts will have a clear understanding of Oracle’s inner workings, empowering them to optimize performance and navigate the platform with confidence.
