You must declare a study as a DDE study in order to use the DDE functionality. This is done in the Study Configuration application using the DDE tab as shown in the figure below. When the tab is selected, you can use the checkbox to tell the system the study will use DDE. You can also tell the system which sites are DDE sites by checking the corresponding checkboxes. This allows you to create a Hybrid Study. A Hybrid study allows certain sites to contribute data with paper that is entered by the Website Host, using DDE. It also allows certain sites to do their own data entry using the EDC portion of Clinical StudioTrialKit. By declaring which sites use DDE, you are actually defining if the study is EDC, DDE or both (Hybrid).
