SAS Viya Programming
Getting started with SAS Viya Programming
Access the capabilities of the SAS Viya through Cloud Analytic Services (CAS) actions for data access and analytics, run directly from SAS applications.
CAS Actions
SAS Viya uses CAS to perform tasks. The smallest unit of work for the CAS server is a CAS action. CAS actions can load data, transform data, compute statistics, perform analytics and create output. Each action is configured by specifying a set of input parameters. Running a CAS action in the CAS server processes the action's parameters and the data and creates an action result. For more information, see SAS Viya Action Programming.
SAS Viya provides a variety of interfaces for running CAS actions, including the following:
- from a SAS session using the CAS procedure. The CAS procedure uses the CASL language for specifying CAS actions and their input parameters. CASL also supports normal program logic such as conditional and looping statements and user-written functions.
- from Python, R or Lua using the SAS Scripting Wrapper for Analytics Transfer (SWAT) libraries.
- from Java using the CASClient class.
- via REST using the CAS REST APIs.
