Models describe the second or child level in the record structure of tables and table types. The configuration entries in a Model Configuration relate to Service and Collection records in many ways. You will find sections entitled Common, Fields, the Service used by this Model (such as a datagrid or calendar), definitions for forms, views and reports.
Models equate to tabletypes for a given table. Thus they are displayed as Bootstrap cards as they tend to have longer references and descriptions.
All that has been explained in the pages for Services and Collections, apply to Models. Only the way that the database records are displayed on the screen is different in that it uses one of the two native Bootstrap 4 mechanisms for displaying lists (list or card) and in this case a Datacard.
