Oracle Database is a multi-model database management system produced and marketed by Oracle Corporation.

It is the world’s most famous database for running online transaction processing (OLTP), data warehousing and mixed (OLTP & DW) database workloads. However, the latest generation, OD 12c Release 2 (commonly referred to as 12.2), is available on-prem, on-Cloud, or in a hybrid-Cloud environment. 12.2 may also deploy on Oracle Engineered Systems (e.g. Exadata) on-prem, on it’s (public) Cloud or (private) Cloud at Customer.

The products follow a custom release-numbering and -naming convention. The partitioning feature introduced in Oracle 8. This allows the partitioning of tables based on different set of keys. Specific partitions can then added or dropped to help manage large data sets. The “c” in the current release, OD 12c, stands for “Cloud”. Previous releases have used suffixes of “g” and “i” which stand for “Grid” and “Internet” respectively. Note that there was no v1 of OD, as Larry Ellison, “knew no one would want to buy version 1”.
