I need a app that can help me work on a database with visual aid, I don't need it to be in a specific language, is only that I can see the workflow to better understand all the links between tables
There are a few tools that can visually display database schemas. If you're using MySQL, you can use MySQLWorkbench. Commercially, there is the Navicat line of products. I haven't used them though. They are available on the Mac app store.
Looking just now, I see Wikipedia has a page on data modeling tools.
