Now that we’ve modified the domain and the notation, let’s use the updated esigner to build a portion of the Business Entity Diagram shown in the ntroduction to this lab.
Press Ctrl-F5 to run the designer. As before, this will bring up the
BizEntityDebugging project in a second instance of Visual Studio.
Double-click on the file named Empty.biz in the Solution Explorer to open it. This wlll bring up the empty design surface as before. We want to build the diagram shown below:
To start, drag an Entity shape from the toolbox onto the design surface. Double-click on the New Entity header text on the shape and rename it to Customer. Press Enter to commit the change.
To indicate that this is a persistent entity, double-click on the text My Type and enter the text Persistent. Press Enter to commit the change.
Right-click on the shape header area and choose Add->Attribute from the context menu.
Type in Name as the name of the new attribute, and press Enter to commit the change.
Use steps similar to the above to create the Account Entity, with Credit Line and Amount attributes.
In the toolbox, click on the Association tool. Click first on the Customer entity, and then on the Account entity to create the association between Customer and Account.
Make sure the connector you just added is selected, and press F4 to bring up the property grid. Set the value of the SourceMultiplicity property to 1, to indicate that in our example, each account is associated with a single customer.
Also notice the RelationshipType property that now appears in the property grid. This is a result of adding the new property to the domain model in task 4. Type some text into this property, and notice that it appears on the diagram. This is a result of modifying the designer notation in task 5.
Press Ctrl-S to save the business entity diagram.
