I am working on modeling a database and get the entity relation diagram.

i would like the tutor to evaluate and provide me suggestions on my data modeling to strengthen my Entity relation diagram.

ideally the tutor could be familiar with Tableau and data mining.

Attached the summary of my database modeling, entities, data sources, etc.

regards

Ruben
