A model is a specific collection of elements/objects related to a modeling notation (BPMN, Conceptual, etc.). For example, the Human Resources BPMN model would contain those objects associated with the business processes of HR: tasks, swimlanes, gateways, etc. A model is where the object “lives”. i.e., objects are stored within a model, but can be visualized in other formats such as a visual diagram, grid editor, etc. In Business Process Modeling you can choose whether to create a model in “Validation” mode, which enforces the rules of the specified notation, or with validation off, which allows you to use the visual objects without being constrained by the rules of the notation. Nested models are allowed. The file extension of a model is .exm.

When you create a workspace or project in ER/Studio BA you are given the opportunity to create a new model. You can have “nested” models with a model. These nested models can also contain diagrams as shown in the following graphic.


Elements within a model can be displayed two different ways in the Model View tree:

Command Description Example

Grouping by Object Type

When you click the Group by Object type
icon (

), elements are sorted by type,
for example, a Task node contains all of
the tasks within the model. Under each
node the items are sorted alphabetically,
unless there is a sequence associated
with an object (lanes, for example).


Model View Hierarchy

This is a hierarchal representation of all
elements in a model, in a diagram node,
and in the model node.
