Need record of changing another records in database

[Esmatullaharifi]

Hello Dears!
I need any code or way that whenever any field of a record according to unique ID changed the code must save the changed field name and the current date in a specific field in another table (first field store the ID and the second one detail about changes) with add record mechanism. Suppose I have a table about the information of students with the name std_info and another info_report and when any changes make to the any field of std_info the field number and the unique ID to the table info_report. I want to use this system to record which user make changes to which records.
Thanks,
I looking forward to your help.
