E/R Model

The connection between the broad variety of items and the historical person that we chose to describe can still appear uncertain. For this reason, we decided to produce a graphical representation of the entities that characterize our scenario and the relations among them, providing a more articulated context to the content of our project. The entity-relationship model follows a concentric pattern and it uses natural language to name its elements, without defining what is their real nature. Proper definitions will be provided later in the project.
