Oracle 21c版本：实现更多新功能

Oracle Corporation has never ceased to amaze its users with upgrades and newer versions over the years. Continuing the trend, Oracle 21c was released with a wide range of new features and improved functionality. It promises its users with faster and stronger database capabilities with cloud-native and automation tools than its predecessor, Oracle 19c.

Here are some of the new features that Oracle 21c offers:

1. A whole new set of JSON features

Oracle 21c provides an extended set of JSON features to support RESTful services and other modern applications. It includes faster JSON parsing and execution, new SQL/JSON Query functions, and other features such as JSON_TRANSFORM and JSON_UTILITIES.

2. Native Multitenant architecture

The multitenant architecture introduced in Oracle 12c has been enhanced in Oracle 21c. This native multitenant architecture provides a more streamlined approach to managing cloud databases with increased flexibility and cost-effectiveness. It helps users to reduce the number of databases needed by consolidating all related applications within a single multitenant contner database.

3. Blockchn table

Oracle 21c features a blockchn table that allows users to store the blockchn data in a secure and immutable way. It provides a mechanism to track transaction history and helps to protect data from tampering or deletion.

4. Automatic indexing

With the introduction of automatic indexing in Oracle 21c, DBAs no longer need to worry about manual index creation and updating. It eliminates human error and ensures that the index is optimized for the specific workload. Automatic indexing uses machine learning algorithms to analyze the workload, and then creates or updates the index accordingly.

5. Native JSON datatype

In Oracle 21c, a new JSON datatype has been introduced which improves the efficiency of JSON data storage and retrieval. It allows the JSON data to be stored as a binary format, which makes it faster to query and retrieve data.

6. Real-time Statistics

Real-time statistics in Oracle 21c provide a more accurate view of the database performance by providing real-time information about database activity. It allows DBAs to identify performance bottlenecks in real-time and take corrective action.

Overall, Oracle 21c provides a range of new features and improved functionality that are designed to help users in building secure, high-performance, and cost-effective cloud-based applications. It integrates cloud-native and automation tools, making data management and application development much easier than before. With the new features such as blockchn table, automatic indexing, and native JSON datatype, developers can build and deploy modern applications with greater ease and efficiency.
