Entity-Relationship-Diagramm-Erzeuger

A simple tool to generate Entity-Relationship-Diagrams based on text input or directly from a PostgreSQL database. The format of the text schema is inspired and based on "erd" by Andrew Gallant.

Fork of edgycircle/erde with fixes added to suit our development.

Motivation : Auto generating ERD from database

There are online tools like genmymodel which allows to build ERD diagrams.

We wanted a way where from a database we could draw a picture. This helps an instant update of schema and not making it stale.

Hence we would create make targets that gets triggered which generates schema, from the Makefile in our rust aran api server.
