What is the structure of the document of high-level designer (HLD)?
Preparing for entry, and tickets have this question: "document Structure of high-level designer (HLD)". I know what it is, but I always thought that the HLD is an optional document (that is done just for convenience). And I've never seen clear rules of its structure.
Can anyone give me the structure in General? Somewhere there is a description?
Thanks in advance for the answer!
