This program can modify the dataset (`work.staging&x`) that is created in the staging area, which is useful for augmenting data / applying complex DQ rules.

+# Data Controller for SAS® - System Requirements
+
+## Overview
+The Data Controller is a SAS Stored Process Web Application, deployed into an existing SAS platform, and as such has no special requirements beyond what is typically available in a SAS Foundation environment.
+
+## Backend
+A SAS Foundation deployment of at least 9.4M3 must be available. Earlier versions of SAS can be supported, on request.  A SAS Stored Process Server must be configured, running under a system account.
+
+## Mid-Tier
+A web server with `/SASLogon` and the SAS SPWA must be available to end users
+
+## Frontend
+All major browsers supported, including IE11 (earlier versions of IE may not work properly).
+For IE, note that [compatibility view](dci-troubleshooting#Internet Explorer - blank screen) must be disabled.
