Oracle Database 11g provides robust security mechanisms to safeguard sensitive data and comply with regulatory requirements.
- Transparent Data Encryption (TDE): Encrypts data at rest to prevent unauthorized access.
- Database Vault: Enforces separation of duties and limits access to sensitive data based on user roles.
- Fine-Grained Auditing: Tracks and monitors specific database actions to detect anomalies and unauthorized activities.
- Secure Backups: Ensures encrypted backups to protect data integrity during recovery.
6. Partitioning Enhancements
Partitioning improves database performance and manageability for handling large and complex datasets.
- Interval Partitioning: Automatically creates new partitions based on data values, simplifying maintenance.
- Reference Partitioning: Enhances performance for complex queries involving related tables by aligning partitions.
- Sub-Partitioning: Allows finer-grained partitioning strategies for optimal data organization.
- Query Optimization: Improves query response times by enabling targeted data access.
