Data Model
The entities marked in yellow 'grey' background color will hold master or template data, whereas the others are considered to store transaction data.

This "duplication" of data is motivated by the fact, that flecsimo operates as an didactic system which makes every step in data communication transparent and persistent. This will allow detailed analysis on every level.
