Teradata Viewpoint is Teradata's strategic and innovative SOV (single operational view) for Teradata DB, Aster, and HDP Hadoop systems management and monitoring that enables Teradata's Unified Data Architecture (UDA).
Teradata Viewpoint is a web portal that is a container for portlets. A portlet is a self-contained component that a portal user can display on one of their portal pages. Teradata Viewpoint can host Teradata portlets as well as 3rd party portlets that conform to the JSR-168 standard. Using this developer guide, you can also create your own custom portlets and deploy them to your Teradata Viewpoint server.
JSR-168 Portlets are written in Java and packaged as a Java WAR (Web ARchive) file. The following sections of this document will give a more detailed description of the components of a portlet.
