How to implement the program?

Question

Software design

Good day, friends!
I have a question regarding the implementation of the project, and more specifically, how to design (invent) the architecture of the program?
That is, I received the TK, I can imagine how the program works, but I have no idea how to implement it through code, how to connect all this.
What classes are needed, what objects, methods, etc.
What is done in such cases?

Answer 1

Keywords:
- Object Oriented Analysis and Design
- UML
- Use case's
- Class Diagramm A

There are, of course, many books on this subject. Depending on the state of the project, different methods are used. Otherwise, this question cannot be specifically answered.

Answer 2

I won’t speak for everyone, because in my opinion it’s individual for each architect,
I personally draw up a “mind map”, that is, a block diagram (a block is a separate class) who does what, what he sends where, at first just stupidly following the technical task, so that this roughly completed the task, then refactoring - how to make it easier, which block to throw out (for example, duplicates any other), change the links. That's why I sit down to write code, because it's easier to fix it in a scheme than in hundreds of lines of code. And, of course, "experience".

To dance from the fact that to break the functionality of the program into logical modules - these will be your classes. They are already divided by what they do - into methods and properties. And so on, according to the principle "We divide into modules, group modules of the same type, repeat."
And the rest - read about the patterns, in the course of studying them you will understand everything yourself. At least 5 patterns you must understand before taking on a serious project. Not to know by heart - namely, to understand what is being done and why.
