Is ERD part of UML? I find ERDs useful representations of databases. They can be generated automatically and are very good for quickly locating the right tables for a query. So I wanted to add a comment stating this to the parent - but then I googled to check if they really are part of UML - and it seems that they predate UML and are not really related.
- neilv 3y agoA subset of UML's static object modeling diagram notation (which they adapted from OMT) can be used like ERDs, for a relational database without an ORM.
- codeulike 3y agoCorrect uml didn't have anything to say about relational databases. I use two types of diagrams: Erds and Random blocks and arrows and icons that mean whatever I want them to mean for that particular diagram, based on whatever concept I want to communicate at that point. Maybe it's network architecture, maybe it's dataflows, maybe it's software components. Each diagram comes with some text explaining what it represents.
