Which of the following features is provided by Oracle Autonomous Database?

Oracle Autonomous Database is designed to handle various types of workloads and includes several built-in features that enhance its functionality. One of the key features is transaction support, which ensures that database operations are executed reliably and maintain data integrity.

Transactions in a database allow multiple operations to be grouped together in a way that ensures they are completed successfully or not at all, preserving the consistency of the database. This capability is essential for applications that require a high level of accuracy and reliability, such as financial systems.

While replication, data compression, and integrated security are also important features within Oracle's database offerings, the question specifically highlights transaction support as integral to the functionality of the Autonomous Database. Transactions enable users to ensure that their data processing maintains high accuracy and consistency, which is crucial for many applications.

In summary, the emphasis on transactions points to the foundation of reliable database operations, making it a defining characteristic of the Oracle Autonomous Database.
