Oracle 28221: Opening the Doors to a New Chapter

Oracle 28221 was released in September 2017, and it marked a new chapter in the history of the Oracle database. This latest release includes a number of new features and enhancements that make it more useful and powerful than ever before. Let’s take a closer look at some of the key changes.

1. New Features for Developers: The new release includes a number of new features that are designed to make the job of developers easier. One of the most notable features is the ability to use PL/SQL functions in the SQL commands used for queries. This allows developers to write more complex queries without having to resort to multiple SQL statements.

Another important new feature is the introduction of hierarchical queries. Hierarchical queries allow developers to retrieve data from multiple levels of a database hierarchy with a single query. For example, it might allow you to retrieve all the data associated with a particular customer, including data from related orders, invoices, and payments.

2. Improved Security: Security has always been a major concern for databases, and Oracle is no exception. The new release includes a number of security enhancements that make it more secure than ever before. For example, it adds support for the use of SSL/TLS for database connections, which ensures that data is encrypted as it travels between the client and server.

Another important security enhancement is the introduction of a new encryption algorithm called AES256. This algorithm provides the highest level of security for data stored in the database, and it ensures that sensitive information is protected agnst unauthorized access.

3. Faster Performance: Oracle 28221 introduces a number of performance enhancements that make it faster and more efficient than ever before. One of the most significant changes is the introduction of in-memory column-store technology. This technology allows frequently accessed data to be stored in memory, which speeds up queries and reduces the amount of time it takes to retrieve data.

In addition, the new release features a number of improvements to the query optimizer, which is responsible for deciding how to execute SQL queries. These improvements make it more likely that the optimizer will choose the most efficient execution plan, which leads to faster query times.

Overall, Oracle 28221 is a significant new release that offers a number of important improvements and enhancements. Whether you’re a developer, a security expert, or a database administrator, you’ll find something to like in this latest release.
