Customization
Full customization of the client interface and even the manner in which actual data is stored are possible using the ClearQuest Designer which provides a drag-and-drop interface for laying out the client data input Forms.
The designer allows administrators to create and modify Record Types, Fields, Lists, hook code and scripts in a simple fashion.
Making changes in the ClearQuest Designer modifies a particular version of a Schema (or creates a new version).
Once an administrator is satisfied with their changes, they are able to test them without impacting the live production system by deploying the new Schema version to a Test Database associated with the Schema in question. Once testing is complete, the new Schema version can be applied to the production User Database such that all users will have access to the new schema. Note that the ClearQuest Designer performs a number of checks on the changes made by the administrator to ensure that the constraints have not been violated. This minimizes the chance that erroneous changes will be "rolled-out" to general ClearQuest users.
ClearQuest 7.1 introduces the ability within the designer to "diff" two arbitrary versions of a particular schema to allow the administrator to see easily what changes have been made.
