Back in 1976, the SAS Institute was founded, SAS was an acronym for statistical analysis system. But a lot has changed since 1976, SAS started out as a statistical language and has changed a great deal over the years. SAS now offers solutions for Data warehousing, data mining, OLAP, data visualization, applications development, along with the original stat formats. SAS now works on a wide range on servers and platforms from Windows NT to Unix. SAS can be found from the census bureau to the IRS and postal service, and universities and colleges around the world.
