History of SAP R/3
The first version of SAP's flagship enterprise software was a financial Accounting system named R/1 called as YSR. This was replaced by R/2 at the end of the 1970s. SAP R/2 was in 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. With the advent of distributed client–server computing SAP AG brought out a client–server version of the software called SAP R/3 (The "R" was for "Real-time data processing" and 3 was for 3-tier). This new architecture is compatible with multiple platforms and operating systems, such as Microsoft Windows or UNIX. This opened up SAP to a whole new customer base.SAP R/3 was officially launched on 6 July 1992. It was renamed SAP ERP and later again renamed ECC (Enterprise Core Component). SAP came to dominate the large business applications market over the next 10 years. SAP ECC 5.0 ERP is the successor of SAP R/3 4.70. The newest version of the suite is SAP ECC 6.0.
