Served data
The data server mediates correlator access for Web Start, 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.
