Five former IBM employees founded SAP in 1972 in Germany. The vision was to develop standard application software for real-time business processing. The first releases, called R1 and R2, were mainframe-only applications. SAP started with a set of Financial applications and then added logistics, manufacturing, and HR. In the 1980s, they moved to a true 3-tiered client-server solution and by the early 1990s, R/3 was released to the market.
In 2000, SAP renamed their solution mySAP and released the latest version of SAP, ECC or Enterprise Core Component, and the most recent release is ECC 6.0.
