Core Mindsets for Oracle Professionals

1. Data is the Heart of the Enterprise

Oracle is an enterprise-grade system. Always prioritize data consistency, security, and recoverability. Data loss is not an option.

2. Think in Transactions

Understand that business operations are transactions. Master ACID properties to ensure every operation is "all or nothing," maintaining data integrity.

3. Architecture is the Foundation

Oracle's power comes from its complex architecture (instance, schema, tablespaces). Understanding this structure is key to effective management and troubleshooting.

4. Performance is Engineered

Performance is a feature that must be designed. Always think about execution plans, indexes, and efficient SQL. Don't just make it work, make it work fast.
