Creating the Model Class

The first step in creating our Zen MVC data entry form is to create the model class. The model can consolidate data from a variety of different sources. For example, the model can include data from all or part of several different Caché tables. In our case we use the data from a single data table — MVFILE.PERSON.

  1. On the Studio Menu Bar click File–>New to launch the New dialog. Click the General tab.

  2. Enter the following on the first screen of the New Class wizard:

    1. Enter a package name: MVFILE

    2. Enter a class name: PersonModel

    generated description: newmodelclass2 20142

    Click Next

  3. On the Class Type screen, click the Extends button and then either select or enter %ZEN.DataModel.ObjectDataModel.

    generated description: newmodelclass3 20142

    Click Finish.

  4. Finally, we set the default language of the class to MVBasic. Do this by adding [Language = mvbasic] to the class declaration.
