The original SAP idea was to provide customers with the ability to interact with a common corporate database for a comprehensive range of applications. Gradually, the applications have been assembled and today many corporations, including IBM and Microsoft, are using SAP products to run their own businesses.

The R/3 system runs on a number of platforms including Windows 2000 and uses the client/server model. The latest version of R/3 includes a comprehensive Internet-enabled package.

SAP has recently recast its product offerings under a comprehensive Web interface, called mySAP.com, and added new e-business applications, including customer relationship management (CRM) and supply chain management (SCM).

As of January 2007, SAP, a publicly traded company, had over 38,4000 employees in over 50 countries, and more than 36,200 customers around the world. SAP is turning its attention to small- and-medium sized businesses (SMB). A recent R/3 version was provided for IBM's AS/400 platform.
