Oracle EE offers sophisticated security tools. Features like Transparent Data Encryption (TDE) allow data to be encrypted on the hard drive without requiring changes to the application code. It also offers fine-grained access control, Data Redaction (hiding sensitive data like credit card numbers from unauthorized users in real-time), and robust auditing capabilities to track who accessed what data and when.
Perhaps the most defining feature of Enterprise Edition is RAC. In a standard database setup, if the server hardware fails, the database goes down. With RAC, multiple servers (nodes) can operate on the same database simultaneously. If one node fails, the others pick up the workload instantly. This provides "active-active" clustering, ensuring zero downtime for hardware maintenance or failures.
It is impossible to discuss Oracle EE without mentioning licensing, which is often cited as its most complex aspect. Oracle typically licenses by the "Processor" core or by "Named User Plus." The cost is high, and features like RAC or Partitioning are often sold as extra-cost options on top of the base Enterprise license. This has led to a trend where companies use Enterprise Edition for their most critical systems but migrate less critical workloads to Oracle Standard Edition or alternative databases to control costs.
