Full Data Model captures a lot more data than what the packaged Prognosis Reports display which enables the customer to create new custom reports. A Data Dictionary is available to pick out field needed and identify the table to join. Choosing the Full Data Model does have sizing implications.
Abridged Data Model captures only the base SQL tables that are used to populate the packaged Prognosis Reports. Custom Reports can still be created but only based on the limited SQL tables provided. This Data Model is ideal for reducing sizing but the downside is not having the ability to create custom reports with new data.
