Why Map Models?
Mapping of process models to data models
ensures completeness of analysis.
enables sharing of data across business units and
functions.
guarantees that the there is a supply of data (entity) for
all data needs (activity).
ensures that data is available when needed.

4 Model Mapping Steps

•Mapping of process models to data models
STEP 1: Map entities to arrows.
STEP 2: Map attributes to arrow entities.
STEP 3: Identify process action(s) upon entities.
STEP 4: Identify process action(s) upon attributes.

•Occurs at the leaf level.

Process Modeler and ERwin DM
• Process Modeler can export and import Data Model
information to and from ERwin.
– further define business activities.
– cross-validate function models and data models.
– improve model quality and consistency.
– reduce development time. Target Server Database

Integrating ERwin and Process Modeler
• The ERwin Modeling Suite offers links between ERwin
data models & Process Models
–From ERwin to Process Modeler through ‘.eax’ files.
–From Process Modeler to ERwin through ‘.bpx’ files.
• These files are used to synchronize entity and attribute
information in both models.

Integrating ERwin and Process Modeler
• .bpx files are created in Process Modeler to
–export entity and attribute names and definitions into a
new or existing ERwin model.
–export activity names from Process Modeler resulting in
the creation of subject areas in an ERwin model.
