Transfer adalo app to code app


after starting with adalo, I have this question

If your database in adalo is very large and has relationships between them, wouldn’t it be impossible to code this app?

imagine that the user has 8 relationships with others and on top of that has location, reviews, data… would it be possible?

and if it went well and you had hundreds of users registering per day I see it even more complicated.

What do you think?
