The CDS enables secure workflow, distributed queries and web application single sign on. The purpose of this guide is to provide insight into the installation and administration of CDS. This guide assumes that you have already have a technical understanding of the CDS; for more information on the technical aspects of the CDS please consult the [Design Guide|cds143:Design].
