Database Creation

I am a beginner at Arduino coding which means I am not well equipped with the knowledge required to perform a task such as the one given below:
Write a program that maintains a database of dates of birth of 12 users. I have
to give each of them a user id number (01-12) and ask for his/her date of birth.

Can someone please suggest what type of commands I can look into in order to create this type of database.

Thank you,
Anon

I assume this is a lightweight database as a class assignment.

Look into an array of structs.

We should have a special section for the homework.

With no reply buttons.

Man, that's harsh. While this one should have the reply button removed, I have no problem with folks that present the work they have done and ask us to go on a bug-hunt or explain compiler errors.

Often, we don't know whether those kinds of questions are homework or not, and it does not really matter.

It does matter. One can read the documentation, and try stuff, and actually learn.

Or, one can post here, explain that it is homework, and ask for hints, and get unstuck.

Or, one can post here, hiding the fact that is homework, and expect us to write the program for them.

If one posts here, and says that they have a personal project that they need help on, I'm willing to help.

If one posts here, saying that they have homework that they put off, and they don't have time to learn programming, I'm less inclined to help.

it is not a homework assignment. I want to a project but for that I need to learn the Arduino language properly first. So i found for myself a few assignments that i thought will help me in learning the language. I do not have to show or submit these to anyone.
