Façade Layer

At the façade layer the evidence generator generates a single process class per product which contains all of the functions required for evidence maintenance. For each single entity at least the following functions are added to this process class:

create<Entity Name>Evidence
read<Entity Name>Evidence
modify<Entity Name>Evidence

Similar to the service layer, there may be additional functions created to deal with some of the more specialized scenarios but again these will not require any input from the developer.

Note: No list<Entity Name>Evidence function is listed above as the generic listEvidence function on the Evidence facade is used instead. This also accounts for no list<Entity Name> function on the Service Layer.
