Each of the modeling entities in frePPLe has its own input screen. A first screen shows a list of objects of a certain type, and a second screen allows a user to edit specific records. Import and export into CSV format are available for easy integration with office tools.
The default data model maps very closely with the internal representation in the frePPLe engine. See the Reference Manual for the description of each model and its fields.
Note that it is pretty straightforward to extend/restructure the data model to match your own domain model. During an implementation additional data types can be added that map more accurately to your business and/or data sources.
