A Quality Model for Conceptual Models of MDD Environments 121
an application and the system, the OO-Method MDD approach specifies
views. A view corresponds to a set of interfaces, which are the communi-
cation point between agents and classes of the structural model. When the
views of a system have been defined, the interaction model of each view
must be specified.
The interaction model allows the specifi cation of the graphical user in-
terface of an application in an abstract way [40]. To do this, the interaction
model has a set of abstract presentation patterns that are organized hierar-
chically in three levels: access structure, interaction units, and auxiliary pat-
terns. The fi rst level allows the specifi cation of the system access structure. ...
