Introduction to Analytic Store Scoring

In the July 2015 release of SAS 9.4, the SAS Scoring Accelerator for Hadoop, SAP HANA, and Teradata support complex model scoring, using analytic stores. With complex models, the traditional descriptive code is no longer adequate to express such models due to the huge amount and variety of information that is needed. Analytic stores present themselves as the alternative to the old style of scoring with code generated by the underlying engine.
Three files are required for analytic store scoring by the SAS Scoring Accelerator:
  • the analytic store file
    An analytic store is a binary file that contains information about the state of an analytic object. It stores information that enables you to load and restore the state of the analytic object and set it in a score-ready mode. The analytic store is transportable. That is, it can be produced on one host and consumed on others without the need of the traditional SAS export or import.
    By default, the filename is score.sasast. However, any filename can be specified.
  • the score code
    The score code is a DS2 program.
    By default, the filename is score.sas. However, any filename can be specified.
  • an XML file that contains the scoring variables and other properties that are used and created by the scoring code
    By default, the filename is score.xml. However, any filename can be specified.
