Approve and disapprove a transaction

Question

i want to develop a contract student in which student sign a transaction to update its record and owner would be able to approve or disapprove this transaction how would I able to do this.

Answer 1

A sketch:

mapping(address=> bool) students;
mapping(uint256 => bool) isTransactionApproved;

modifier onlyStudent {
 require(students[msg.sender] === true, 'Only students');
_;
}

function approveTransaction(uint256 id) external onlyStudent {
 isTransactionApproved[id] = true;
}

Answer 2

Have the student submit all the modifications they want to do in a transaction, store them somewhere in a pendingModifications array or something like that, idk. And have a function for the owner so they can approve/reject the changes, clearing the pending array and potentially modifiying the data.
