Program for complex visual design of applications - does it exist?

Question

Software design

There is a Swagger for the API, there are all sorts of things for MySQL, but is there something complex, well ...

I don’t even know how to put the question correctly))

Well, for example, I need to design a CRM and somehow estimate the entities in the project, the relationship between them, but this is not necessarily a database, mb some service layers will need to be displayed, or something like that. Something in the spirit of DDD, and to make it visual.

Does this even exist in nature and does it have a name for Google?

Many thanks in advance for a clear answer.

Answer 1

This is architecture design. It works in several planes and there are no adequate tools and cannot be. There are archi, there is a C4 model, but this is the limit for today
