You will want to know if you need one set of values or if multiple sets are appropriate: a Single set of Variables or a List of sets of Variables. Each Object Variable you create for any Model can be unique in this decision. For instance, if you represent a company, you might use a Single Object Variable to collect that one company’s information. You might then create a List of Object Variable to collect employee contact information for that company. Both Object Variables can use the same Model as you will most likely be looking for similar information.
