Oracle Database 21c is the latest version of Oracle's widely used database software and offers numerous improvements and innovations compared to previous versions.
One of the most important new features of Oracle Database 21c is the support of JSON and XML natively. This means that users are now able to store and process data in these formats directly in the database without having to convert it to another format first. This facilitates the integration of data from external sources and simplifies the processing of unstructured data.
Furthermore, the performance of Oracle Database 21c has been improved, especially when processing queries with large amounts of data. This is achieved by supporting in-memory columnar compression, which speeds up read and write operations.
Another highlight of Oracle Database 21c is the introduction of Multi-Tenant Pluggable Databases, which allows users to host and manage multiple databases in a single instance.
