Translation of the principle of JOIN/UNION using Venn diagrams? Not necessarily.

In the article on the jOOQ blog, the author highlights how using Venn diagrams to explain joins in databases can be misleading. Instead, they suggest employing more understandable and direct visualization methods. While Venn diagrams are popular, they often fail to capture the complexity of relationships in databases. Rather than illustrating what occurs with joins, they can mislead their audiences, leading to incorrect interpretations. The author encourages considering alternative approaches that can more effectively clarify join concepts, such as SQL code examples or more detailed data visualizations. By simplifying such explanations, we can significantly enhance the understanding of database topics among audiences, which is crucial in the field of IT.
