Okay..
I am making a web base application,that will be connected to a sms gateway.
It is basically an attendance app for colleges.
The Attendance will be updated using a sms by the teacher.
Now,the main part-
What I want to do is,the teacher should not be able to correct the attendance after 10minutes of sending the 1st message.i.e,the database should accept a correction or new message for the same class and the same teacher only for 10 minutes after the 1st attendance is recieved in the database.
So only recieving from a particular number should be blocked and also only if it is for the same class…
I hope the question is clear 😮
Thankyou
This is not the sort of thing that you should be enforcing at the DB level, it belongs in your application code. If you can’t connect time, number & class together in your DB, it’s time to change your schema.
