N-nary relations #19

Open RainbowZephyr opened 8 years ago

RainbowZephyr commented 8 years ago

First of all, I would like to applaud you for this project I have been looking for a tool like this for a long time.

Secondly I want to ask if it is possible to support N-nary relation ships between tables.

Could you say more about what it means to support n-ary relationships? On Jun 7, 2016 5:13 PM, "RainbowZephyr" notifications@github.com wrote:

Something like this: https://www.dlsweb.rmit.edu.au/toolbox/ecommerce/tbn_respak/tbn_e2/html/tbn_e2_devsol/images/ternary.gif

a relationship which joins multiple tables togther

There's no support for that. If you can find a simple way to add to it, I'd be happy to accept a PR.

Is there a way to create a generalization from entities?
