What is the Database and Relational Database Management System (RDBMS)

Oracle Database Version History

Oracle was founded on June 16, 1977 by Larry Ellison, Bob Miner and Ed Oates under the name Software Development Laboratories (SDL). Until 1979, the company did not succeed with this name, and in 1979, three adventurous friends who changed the company name to Relational Software Inc worked in Relational Software Inc. until 1982. The brilliant trio, which has consistently focused on Database management systems and made its first database trial with IBM, failed.

In one of the following experiments, the Oracle Database System developed under the leadership of Bob Miner. In 1982, the name of the company was identified with the name of its products and changed to Oracle Systems Corporation. It was changed to Oracle Corporation in 1995 and this name has continued to this day.

Oracle Release Versions

TOP Features according to Version of Oracle database from the first version are as follows.

Oracle 8

RMAN (Recovery Manager), which is the backup and recover tool of Oracle database, and Partitioning feature, which makes a great contribution to the Database management system in terms of performance, were introduced with this version.

Disaster Recovery feature called Dataguard is released with Oracle 8.

Oracle 9

The most important feature in this version is undoubtedly the Real Application Cluster (RAC) feature. With this feature, Oracle Instance, which is installed on multiple servers at the same time, provides high availability of databases, which we call high availability.

There is still no feature like RAC (active-active) in other RDBMS. The RAC feature has become a sine qua non for corporations, especially for customers with instant money flows such as banking and insurance, which we call business critical systems.

Oracle 10g Release Date

Oracle 10g is released at 2003. With Oracle 10g, we now have the ability to manage Oracle’s storage management from operating systems, which we now call Automatic Storage management. The Real application Cluster feature, which comes with Oracle 9, has been improved and the Grid Infrastructure feature has also come with 10g.

Flashback feature, which is one of the most important features for database administrators and shortens the recover on user errors, was also introduced with Oracle 10g.

Advanced Compression and Transparent Data Encryption are also introduced with Oracle 10g.

Autonomous Database

Oracle Autonomous Database is a cloud-based technology introduced in 2017, designed to automate many of the routine DBA tasks required to manage Oracle databases. In particular, Oracle says that database administrators (DBAs) will have the opportunity to do higher and more strategic tasks rather than routine and tedious tasks . Because lots of DBA tasks will be done by Oracle, thus Oracle will be a self-managed database.

Autonomous Database feature is provided as a cloud service created by machine learning algorithms called self-driving, self-safety and self-repair slogans.

Oracle 19c Release date

Oracle 19c is released at  2019.
