The other day I asked for an analysis or at least an UML diagram since we are having quite some troubles and my boss looked disgusted at me for asking such a question. I’m not a professional backend developer, so I don’t know how it works professionally
This is such a broad question. It’s normal and not normal to do so, it’s also normal not to do so.
If it turns out / becomes evident you need a diagram now now’s the time to create one. You may push quality even without seeing the value in it. In some places or with some people it may be unwanted.
I’m not the one who designed the DB; it’s not a simple DB or project though. The problem is, they “”“found out”“” they had forgotten to implement a very important part and they had to heavily change some parts we had already built upon
What kind of application is it?
