    ER vs. UML

    Hello party people! I have to understand a DB without any primary or foreign keys. First I was trying to understand DB by digging it. Well, I came to oppinion it's impossible untill I construct a concept model.
    What notation to use? UML or to return back to DFD, ER and state diagrams? Personaly I would use UML notation because I can implement a whole project using only one tool.

    What methodology to choose?

    Any ideas?

    Use your tool of choice for modeling. If you are comfortable with UML, it will certainly do the job nicely. I'd be inclined to use something a bit simpler myself.

    I see using UML for database modeling as something akin to calling a contractor to come change your burned out lightbulb... A bit of overkill even though it would fix the problem!

    "I have to understand a DB without any primary or foreign keys."

    That's not a very good database!
