Served data
The Data Server mediates correlator access for applet, WebStart, and local deployments; the Display Server mediates correlator access for simple thin-client, Web-page deployments.
The Data Server delivers raw data from which deployed dashboards construct the visualization objects that they display. The Display Server, in contrast, delivers already-constructed visualization objects in the form of image files and image maps, and therefore no Java plug-in is required on clients of the Display Server.
