• The repository QDCS element is at the top of the hierarchy. There is only one repository, regardless of the number of subordinate environments, products, and hosts.

• Typically, organizations have more than one environment. For example, your organization can have a test environment for verifying deployments, and a production environment that accommodates the live system. The position of the environment element at the secondary level in the QDCS hierarchy allows for the easy movement of product and host deployments between environments.

• Since the 1.7 release, the hierarchy has only contained two product elements. These elements are for QAD’s QXtend and Workflow products.

• Typically, there are several host elements. The elements enable the deployment of QAD QXtend in various configurations. Each host usually contains one or more QAD QXtend components based on component dependencies and organizational deployment requirements.
