Please do not write a sentence or put hyperlink in Relevant Tags section. Kindly move the sentence 'how to build a school management software?' sentence into the Description. Try 'web-based school-management-software' for the Relevant Tags, also look out on the net for open source projects having such topics.
P.S. IMHO SQL will also be needed as school management system will definitely be needing database to store information.
Thanks for understanding 👍
