SAP R/2 was a mainframe based business application software suite that was very successful in the 1980s and early 1990s. It was particularly popular with large multinational European companies who required soft-real-time business applications, with multi-currency and multi-language capabilities built in

SAP R/3 is a client/server based application, utilizing a 3-tiered model. A presentation layer, or client, interfaces with the user. The application layer houses all the business-specific logic, and the database layer records and stores all the information about the system, including transactional and configuration data.

R/1 means Realtime One Tier Architecture,

R/2 means Realtime Twoer Architecture,

R/3 means Realtime Three Tier Architecture,
