The OMA introduced a common programmatic interface for reading and writing metadata. This allowed:

SAS Version 9.0 was so foundational that subsequent releases (9.1, 9.2, 9.3, 9.4, and even M6 and M8 maintenance releases) built directly upon its architecture without a Version 10. In essence, the born in 2004 continues to serve customers today. Sas Version 9.0

, released in 2004 under the internal codename "Project Mercury," marked a definitive turning point in the evolution of the SAS System. It transitioned the platform from a purely programmatic environment into a modern, multi-threaded intelligence platform designed to serve both expert coders and general business users.

Released in 2004, (internally codenamed " Project Mercury ") represented one of the most significant architectural shifts in the history of the SAS Institute. Designed to make advanced analytics accessible to a broader range of business users, Version 9.0 introduced fundamental changes to how the software processed data and how users interacted with it.

Surprisingly, the MEDIAN function was officially added in Version 9.0 to calculate the middle value of a data set directly.

Performance-wise, SAS Version 9.0 was optimized for threaded processing. This allowed the software to take full advantage of multi-processor hardware, significantly reducing the time required to process massive datasets. For industries like banking, healthcare, and pharmaceuticals, where data volumes were beginning to explode, this increase in speed was a game-changer. The version also brought significant updates to core modules like SAS/STAT and SAS/GRAPH, offering more sophisticated statistical procedures and better visualization options than ever before.

SAS 9.0 supported complex procedures, including logistic regression , ANOVA, and survival analysis, which were widely used for analyzing maternal and neonatal characteristics and other clinical or social research data.
