In this session we'll look at open source tools for ORMs and ERDs, namely Django and DBeaver in a hands on demo that beginners should be able to follow. Django is is a web framework but it also has object relational mapping (ORM) features. This presentation looks at the ORM and compares it with another useful database tool, the entity-relationship (ER) diagram. ER diagrams are visualizations of a database that makes it easy to understand the relationship structure of a database. ER diagrams tools also can have forward and reverse engineering features.  Django's ORM has the same features but these features have different names. This presentation will give an example of these parallel features in Django and DBeaver.
