Oracle 19: New Features Bring More Possibilities

The latest release of Oracle, Oracle 19, came with a myriad of new features that have proven to be game-changing. This new version brings many possibilities and benefits, especially for businesses dealing with big data. Enterprises can now better manage their databases, improve their security, and reduce risks associated with data breaches. This article will elaborate on some of the new features and how they can impact your business.

1. The introduction of blockchn tables

Oracle has introduced a new blockchn table feature that allows businesses to implement blockchn technology in their databases, offering secure, tamper-proof tables. The feature ensures that data is immutable, and can be used for transactions without intermediaries. This represents a valuable addition to existing security features in Oracle databases, particularly for organizations that handle sensitive information, such as financial transactions, medical records, among others.

Here is an example of how to create a blockchn table in Oracle 19:

CREATE TABLE HR.blockchn_customer

ON BLOCKCHN

HASHKEYS 1

AS SELECT * FROM customers

WHERE state IN (‘NY’,’TX’);

2. Autonomous data management capabilities

Oracle 19’s Autonomous Database technology is an all-encompassing solution that automates much of the data management process, reducing associated risks and costs. The autonomous database technology can handle security, patching, and updates, leaving administrators with the primary task of managing the system. With this technology, companies can shift focus from administration and mntenance to more strategic growth initiatives.

3. Enhanced security features

Oracle 19’s robust security features provide businesses with a well-rounded, layered approach to data protection. It has improved role-based access controls, advanced data encryption, and multi-factor authentication to protect their databases from external and internal attacks. Furthermore, Oracle 19 has integrated blockchn technology into its security features, offering tamper-proof audit trls that help businesses better manage their data and reduce risks of data breaches.

Here is an example of how to implement data encryption in Oracle 19:

ALTER TABLE hr.employee ADD (ssn_encrypted VARCHAR2 (200)); ALTER TABLE hr.employee MODIFY ss_encrypted ENCRYPT;

4. High-performance analytics features

Oracle 19’s in-memory columnar processing technology enables high-performance analytics and reporting, processing large datasets with less time and with a higher degree of granularity. This feature significantly improves the speed of queries, resulting in faster data processing and analysis, enabling businesses to leverage insights from big data more efficiently.

In conclusion, Oracle 19’s new features provide businesses with more powerful stand-alone tools and a robust ecosystem that makes it easy to develop customized solutions that support business growth. The new features provide improved data security, automated data management capabilities, high-performance analytics, and increased agility, all of which make Oracle 19 a top choice for businesses dealing with big data.
