Thanks for posting in the Community!


With Lucidchart you can create Entity Relationship diagrams (ERDs) with customized text styling and relationships between fields and automatically generate database tables and schemas using our SQL import feature. You can read all about this feature here: Entity Relationship Diagrams


We always do have templates to create data flow diagrams (DFDs) and use case diagrams. You can browse our template library here.


Please use the search engine or browse the different categories to see what's available!
