Solution architecture diagram - arrow directions -

-

There are various types of arrows used in the software architecture diagram.

What is the difference between A and B

  1. Single bi-directional arrow between A and B
  2. Two in parallel between A and B Arrow, pointing to an A and B to the other

    Do they mean the same?

    Arrow shows the flow of conversations and information:

    both of them Meaning, it depends on how much information you want in the picture, sometimes it is important to write on the arrow, the information is flowing, so choosing two is better.

    Hope it helps.

    Cheers !!
