How are you all I hope that you all are feeling fine…
I’m a computer science student and we are studying software engineering.
We have an assignment to develop a system analysis report and we choose twitter and we are having some difficulties with nonfunctional requirement could anyone tell us what are they exactly for twitter specially because some if the requirements don’t apply and we don’t know which ones for sure like the longevity requirements are there any and if yes what are they. If you could please provide a full list of them then Ill be really thankful to you.
