I have a field in my tables where the guidance counselor would have to type in Notes about the student. For example, Alex is in Grade 1 and he have an offense wherein he pushed his classmate, that note will be saved in the database. And then when he turned Grade 6 he had another offense wherein he was caught cheating in exams. I would need to create another note for his actions.
What can I do to not overwrite the notes I entered when he was in Grade 1?

Without knowing about the structure of your tables, you could have a table just for notes with a structure like
Where * indicates primary key (compound key consisting of the first two fields). A compound key would ensure a unique primary key.
