About forms
512 InfoMaker
You may want to display this type of relationship in a form. Such a form is
called a master/detail one-to-many form.
For example, the following form displays information about one department at
the top and all of the employees of that department at the bottom:
About the ID column
Note the ID of the department in the master table at the top of the form.
Although you cannot see the ID of the department in the detail table at the
bottom of the form, it is there. The ID has been hidden by moving grid
boundaries to cover the ID column. Since all the ID values are the same, hiding
the values is useful.
If the detail table did not include the ID, the form would not be updatable. If
you forget to include necessary columns, InfoMaker prompts you.
The following illustration shows the database tables that handle the data on this
form: the
Department table and the Employee table in the EAS Demo DB. The
Department table is the master table, and the Employee table is the detail table.
