Why oracle r12 is called r12 and not 12i?

Oracle R12 is named "R12" to signify its position in the sequence of Oracle E-Business Suite releases, with "R" indicating "Release" and "12" denoting the twelfth major version. The earlier version, 11i, included the "i" to reflect the internet capabilities introduced at that time. With R12, Oracle moved away from the "i" nomenclature to emphasize enhancements and new features rather than focusing solely on internet functionality. This rebranding aligns with the software's evolution towards a more comprehensive enterprise resource planning solution.
