Why SIRIS?

SIRIS offers several advantages over the traditional ways of accessing and reporting on student data at Stanford

Ease of Use

The browser-based OBIEE environment provides a much simpler and more portable way to access and interact with the data than the traditional connection via Windows Remote Desktop, and offers many more options for customization than the preformatted BI reports.

Data Model

SIRIS was developed with the end user in mind. The data in SIRIS is restructured into a dimensional model (technically, a star schema), whereas in PeopleSoft it exists in a normalized database. The data model behind SIRIS has been carefully constructed to make slicing, dicing, and aggregating across important attributes much easier.

Groupings and Derived Fields

As part of the restructuring that occurs as the data is loaded into SIRIS, several new fields are added which are of great practical use for many questions about students. These include:

  • Grouping of academic plans into types, e.g. “degree-granting” or “non-degree-granting”
  • Grouping of degrees into levels and types, e.g. Undergrad/Grad or Academic/Professional
  • Ethnicity groupings that meet federal reporting requirements
  • Grouping terms into years, including “Core Academic Year” and “Summer Start Year”
  • Derived fields such as “UG Cohort”, “UG Entry Status”, counts of elapsed or enrolled terms, and more.
