Hello I want help in app for school's project

I'm doing an app for homework and exam dates

But I Don't know how to make The teacher edit in the h.w or exam date and the student just view it (in the same page)

Could anyone help?

You would need an online database where the teacher could post exams and dates, and the students could list those upcoming exams.

If you use one of the tag/value databases like Firebase or CloudDB, use chronologicaly ordered tags in the format courseName/yyyyMMdd to make filtering easier.

I can understand well from this

But if the teacher have single account and the same thing with the student will it make the things easier?

Can you show me the needing codes so I can get the things well

Better you can hire someone to help you with this project. Person will help you to create complete project and also help you to learn.
