drupal simple site

I am a PHP programmer and new on drupal

We are yet planning a school management solution for a school in. We use Drupal for our school and alumni sites.

Here is a list of benefits and functionality we are looking at. Is this doable with Drupal or will we need a proprietary solution. Are there any open source solutions for this use case?

1.An interactive platform for all entities and stakeholders viz. Students, Parents, Teachers, Management, Administrators and the Alumni of the school.
2.connects all the departments of an institution and knits them into a complete whole
