Orientation

This software supports analytical data preparation, variable transformations, exploratory analysis, analytical modeling, integrated model comparison, and scoring. Here are the main components of SAS Viya:

CAS-based procedures run against data that is in CAS. For example, before you can use CAS to work with a SAS data set, you must load that data set into CAS. The following instructions demonstrate the basic mechanics.

Demonstration: Load Personal Data

1. Sign in to SAS Studio.
   1. Open SAS Studio from a URL that is provided by your SAS administrator. For example, you might enter either of the following URLs:

      https://webserver-host-name/SASStudioV (for SAS Studio 5.2, which is available in full deployments)

   2. If you are prompted for credentials, sign in.
2. Start a CAS session.
   1. In the Snippets section of the navigation pane, expand SnippetsSAS Viya Cloud Analytic Services.
   2. Right-click New CAS Session and select Open as program. The snippet opens in the code editor.
   3. In the toolbar, click to run the New CAS Session code.
3. Load a table.
   1. In the navigation pane, right-click Load data to caslib and select Open as program.
   2. In the code editor, edit the SAS data set section so that it looks like this:

      PROC CASUTIL;	LOAD DATA=sashelp.cars OUTCASLIB="CASUSER"	CASOUT="demoTable" PROMOTE;RUN;

      Tip

      CASUSER is your personal caslib. It is available across your sessions. You cannot enable other users to access it.
   3. Select the preceding code. In the toolbar, click to run only the four lines of selected code.
4. Verify that you can access the loaded data.
   1. In the navigation pane, right-click Generate SAS librefs for caslibs and select Open as program.
   2. In the toolbar, click to run the code.
   3. In the Libraries section of the navigation pane, expand LibrariesCASUSER.
   4. Double-click demoTable to open it.

Demonstration: Provide Shared Data

1. Sign in to SAS Studio and start a CAS session, if you have not already done so.
   Tip

   For details, see the first two steps in the preceding demonstration.
2. Create a container for shared CAS data.
   1. In the Snippets section of the navigation pane, expand SnippetsSAS Viya Cloud Analytic Services.
   2. Right-click New caslib for Path and select Open.
   3. In the code editor, edit the snippet so that it looks like this:

      CASLIB demoCas PATH="/filePath/" DATASOURCE=(SRCTYPE="path") GLOBAL;

      Note: Enter a path that is relative to and accessible from your CAS server. You can reference an empty directory.
   4. Click to run the code.
      Note: If an error indicates that you do not have permission to create global caslibs, see Caslib Management Privileges in SAS Viya Administration: SAS Cloud Analytic Services. Initially, only administrators can add global caslibs. An administrator can enable non-administrators to add global caslibs.
3. Give all users Read access to the new caslib.

   In the SAS Studio 5.2 Enterprise edition, complete these steps:

   1. Access the Data page in SAS Environment Manager.
      • Select Manage Environment from the applications menu () and then click in the vertical navigation bar.
   2. On the Data page, select the Data Sources tab. Right-click the new caslib, and select Edit authorization.
      Tip

      Data page functionality is also available in other contexts. See Data Selection Windows and SAS Data Explorer in SAS Data Explorer: User’s Guide.
   3. In the Edit Authorization window, adjust the gauge in the Access Level column to increase access for Authenticated Users from No access to Read.
   4. Click Save.
   5. Go back to SAS Studio.
      • Select Develop SAS Code from the applications menu () .
4. Load data to the new caslib.
   1. In the navigation pane of SAS Studio, right-click the snippet Load data to caslib and select Open as program.
   2. In the code editor, edit the SAS data set section so that it looks like this:

      PROC CASUTIL;	LOAD DATA=sashelp.cars OUTCASLIB="demoCas"	CASOUT="demoTable" PROMOTE;RUN;

   3. Select the preceding code. In the toolbar, click to run only the four lines of selected code.
5. Verify that other users can see the data. For example, ask them to complete these steps:
   1. Sign in to SAS Studio, start a CAS session, and run the Generate SAS librefs for caslibs snippet.
   2. In the Libraries section of the navigation pane, expand LibrariesdemoCas.
   3. Double-click demoTable to open it.

Tip: Automatically Connect and Generate Librefs

For convenience, you can configure SAS Studio to perform the following tasks each time that you sign in:

• Start a CAS session.
• Generate SAS librefs for existing caslibs that have names that are no more than eight characters long.

Complete the following steps:

1. Click Options and select Autoexec file.
2. On the Autoexec.sas tab of the (Edit) Autoexec File window, paste the following code:

   cas casauto;caslib _all_ assign;

3. Run the code.
4. Save the code.
