Easy to use database for HS students
Is there any easy to use database platform that would allow 9th graders to enter data easily (like Google Sheets), and pull data using client-side JS?


Given that you're thinking about Google Sheets as a data entry method, I understand that your goals don't extend to getting the students to implement server-side form handling. But in that case, why do you need a database? It seems to me that the requirements given can be met perfectly well by a hand-coded JSON file.
