Managing your data model Maintain data integrity by updating your data model when changes occur. Use the following techniques to update your data model resources: Defining the fields in a data object Define fields to structure the data that a form displays. You can add fields to data objects and specify the field type, such as Picklist, Boolean, or Text (single line). For example, to include a field that displays a list of available courses in an Onboarding application, you might add a Courses field to a data object, and then select Picklist as the field type. Changing the type of a field To store data in a different format, change the type of a field. Reusing data records Add a data reference list to your data model to refer to data records for a data object. Referencing data from another data object Create reusable data for your application and build easy to maintain forms by using a data reference. Adding data references to forms Enhance your case processing by providing users with a list of data records that they can choose from when they complete a form. By using data references, you integrate the data with the cases in your application.
