Some Explanation about Version
| Major Database Release Number | The first digit is the most general identifier. It represents a major new version of the software that contains significant new functionality. |
| Database Maintenance Release Number | The second digit represents a maintenance release level. Some new features may also be included. |
| Application Server Release Number | The third digit reflects the release level of the Oracle Application Server (OracleAS). |
| Component-Specific Release Number | The fourth digit identifies a release level specific to a component. Different components can have different numbers in this position depending upon, for example, component patch sets or interim releases. |

Oracle Database Versions
Oracle has released various versions of the Oracle database starting in 1979. They release Oracle 8i in 1998 where “i” stand for the internet. They release Oracle 10g in 2003 where “g” stands for grid. Then they release Oracle 12c in 2013 where “c” stands for the cloud. After that, they continued year-wise starting in 2018. So 2018 was 18c Release, 2019 was 19c Release, and so on.
The latest version right now is 21c released in 2021. They are terming some versions as innovation releases and some as Long term releases. Innovation releases have shorter support periods ie. 2 years and long-term releases have 7-8 year support periods. So businesses can choose the release accordingly. Right, 19c is the long-term release, and 18c,20c,21c are innovation releases. The next long term release will 23c
