Requirements for the report on the conceptual design
 
The report on the conceptual design will have to contain at least the following elements:

1. The final conceptual schema.
2. A table associating a brief description with each concept of the schema (both entities and relationships).
3. A description of the design process including the refinement steps that you needed to take, and a justification for each of them.
   This includes also a justification for each redundant concept possibly occurring in the schema.
4. A list of external constraints expressed formally or semi-formally.
5. A precise description (in English) of all the functionalities of the information system.
