Get UML diagram from relational database [closed]

Question

I use PostegresQL 9. Is there a free tool to derive UML diagrams from my databases?

Thanks

Answer 1

For creating ER diagrams by db reflection, I use: DbVisualizer

http://www.dbvis.com/

It's free.

Answer 2

There's also postgresql_autodoc which can create GraphViz or Dia output. The diagrams will likely require further tweaking, though.

Answer 3

There's a free tool called Dia and a plugin called PostDia. They would do it for you.

Plus:

1. it generates postegres sql scheme files too
2. Both are free.

Requirements for PostDia: python and psycopg2, to install the second one:

pip install psycopg2
