I have found some packages to draw ER-Diagrams using Tikz, but I don't like the final result (it has big rhombuses for associations, big ovals for attributes and so on). I'd like to draw ER-diagram like the following one

using these shapes

I am not able to find any package in order to get this result. Do you have any suggestions?

  • The first link is about an er-diagram where an entity is represented by a table and the attributes as its rows (while I'd like to represent them as little circles linked to the rectangle, which symbolizes the entity). The second one is exactly the er-diagram I wish to avoid. – frad Dec 12 '20 at 13:17

  • have you found a solution? I'd like to use that style too – Paolo Cotto Jun 28 '23 at 13:29
  • TikZ-UML exists but I don't think it has necessarily all these specific things. – Qrrbrbirlbel Jun 30 '23 at 22:27
  • @PaoloCotto The problem for me with these questions is that it's not clear what's a shape and what's just and addition. It looks like the small circles aren't part of a shape but an flexible addition. Are the lines from one side around the shape to another side part of the shape or do they somehow specify something of those small circles? – Qrrbrbirlbel Jun 30 '23 at 22:30

One possibility is the MetaPost expressg package which provides facilities to assist in drawing box-line-annotation (BLA) diagrams such as EXPRESS-G, IDEF1X, OMT, Shlaer-Mellor, NIAM, ER, UML and similar diagrams.

On my texlive installation doing texdoc expressg will result in several different examples of its possibilities. To see if it is on your installation do kpsewhich expressg.mp. It can be downloaded from https://ctan.org/pkg/expressg
