I have an E-R Diagram which, for a project, asks me its functional dependencies. The thing is, I don't know how to obtain them. Can someone give me a clue please?
I will put an image of the E-R Diagram. Thank you everyone!

I am trying to use PlantUML (http://plantuml.com/). I want to have my Java project (call stacks) converted as diagram in PlantUML. I see it can generate technical diagrams by writing lines of code/text. I know about text. But, how to give input as java project and get code as diagram? please suggest if you anyone know about it.
Thanks.

So basically, I mean something like UML for designing classes in Object-Oriented programming.
How can we use a diagramming software to design (model) our UIs (Components, props, states, event etc) before writing any actual code?
You can use the https://balsamiq.cloud/ for creating the wireframes of UI before starting the actual code.You can create the mobile view screens for different mobile versions in that.Later you can work on the screens wise.
Once the UI is done you may get the clear idea of what is needed in reactjs states and props values.
Pen and paper ... whiteboard. It might sound like I'm kidding. But I find this to be the best way to model your app. When I'm done with a whiteboard diagram, I take a photo if I need to share it.
It does two big things, imo: 1. it keeps things simple so you get the important stuff figured out without overcomplicating things so you get started coding; 2. it doesn't look too official or polished so you remember it's just a sketch. When it comes time to write your code, your established patterns and conventions should dictate your app architecture and your "wireframes" should just be a reference to look back on.
Again, just my own opinion. There is no single answer to your question.
Doing practise exam questions. Was just looking for some feedback on my attempt at this task. Do you think this caters for what it's asking for, is it missing anything?
This question I found in my DBMS college question paper. I am confused whether it belongs to ER Diagram topic or something else. Please help.
It is related to whole DBMS processes and knowledge specially part of DBMS architecture/design process.
For the detailed explanation over the topic, yes this unbend under UML diagrams - ER diagrams.
