Warning

Before editing the selected business model, ensure that you have the related read-write right and meanwhile, that this business model is not used concurrently by the connected Studio so as to avoid that your editing cannot be saved or any inconsistent error is caused. If being used concurrently, close it in the connected Studio and reload it in this Business Model Designer page.

The Business Model Designer page is equipped with the Shape Repository, the contextual toolbox and the top toolbar that help you to edit the selected business model easily.

Using the Shape Repository for editing

This Shape Repository is composed of two classes of shapes: Interaction shapes and Relationship shapes.

Note

If it is hidden, display the Shape Repository by clicking the icon in the up-right corner.

This Shape Repository holds the same shapes as the Palette does in your Studio: the Interaction shapes in this page correspond to the Business shapes in the Palette and the Relationship shapes correspond to the connecting shapes in the Palette.

These shapes from either the Shape Repository or the Palette are used in the same approach to edit a business model.

For further information about these shapes, see Talend Studio User Guide.

Using the contextual toolbox for editing

The contextual toolbox is provided to simplify further the editing of the selected business model.

To display a contextual toolbox, simply click any of the shapes used as a step by the selected business model in the workspace of this page.

The figure below shows an example of the contextual toolbox around the Doc step in the MDMProject business model.

From this contextual toolbox, all of the shapes held in the side-located Shape Repository are available immediately for editing the current model.

In addition, two more icons appear in this contextual toolbox. They are:

  • : it provides shapes used to replace the selected shape this toolbox depends on. For further information about this replacement, see How to replace a shape.

  • : it opens the monitoring window where you can view the status evolution of the item(s) assigned to the selected shape this toolbox depends on. For further information about this monitoring window, see How to monitor the status evolution of the assigned item(s).

Then you are able to add shapes to this business model or to replace shapes in this business model by means of the contextual toolbox. And if need be, you can as well view the status evolution of the assigned item(s).

The following sections take as example this MDMProject business model presented in the figure to show the details about how to add or replace a shape used therein and how to use the monitoring window.

How to add a shape

To add, for instance, an Actor shape to the Doc step in this example business model, proceed as follows:

  1. In the workspace of the Business Modeler page, click the Doc step to display the contextual toolbox.

  2. On the contextual toolbox, move the pointer to the Actor shape.

  3. Click this shape and a new step is added to the Doc step using the Actor shape.

By default, a Directional Relationship connecting shape is used to connect the Doc step to the newly added step represented by the Actor shape. Then if need be, you can replace this connecting shape with another shape required.

How to replace a shape

To replace, for instance, the newly added Directional Relationship connecting shape with another one, for example, an Bidirectional Relationship connecting shape , proceed as follows:

  1. In the workspace of the Business Modeler page, click the Directional Relationship connecting shape between the Doc step and the newly added Actor shape to display the contextual toolbox.

  2. On the contextual toolbox, move the pointer to the icon to display the available shapes used for this replacement.

  3. Click the Bidirectional Relationship connecting shape and then the Directional Relationship shape is replaced with this connecting shape.

How to monitor the status evolution of the assigned item(s)

When there is(are) item(s) assigned to a shape used by a step or a connection of a business model, a grey icon, a green icon and a red icon may appear either alternatively or concurrently along with this shape

The following figure presents an example of these icons

  • The grey icon appears to indicate the number of the assigned item(s) never executed;

  • the green icon appears to indicate the number of the assigned item(s) whose last execution(s) succeed(s);

  • the red icon appears to indicate the number of the assigned item(s) whose last execution(s) fail(s).

For each of them, when the corresponding items do not exist, this icon does not appear.

Then if need be, you can view the assigned item(s) easily using the monitoring window accessed from the contextual toolbox.

Suppose that you should view the item assigned to the shape named terminal01presented at the beginning of this current section, proceed as follows:

  1. In this workspace, click the shape named terminal01 to open its contextual toolbox.

  2. On the contextual toolbox, click the icon to open the associated monitoring window.

By default, the Job executions view is displayed in this window. In this view, the status evolution of the assigned item, a Job called SimpleJob in this example, is listed.

The Assignments view is accessible by clicking the Assignments tab beside the Job executions tab. In this view, you can read the information about the assigned item, the SimpleJob Job.

The tables below presents respectively details about the elements displayed in the two views.
