How to save values from a vector in a database?

I'm creating an Android app for tcc. I have 3 vectors: coorx[i]; coory[i]; busy[i] . This busy vector is not fixed, so the values have changed according to what the user requests. So I would have to save the value of that busy in a database. What do I do? Best I turn this into an object with the coorx, coory, busy attributes? And if I transform, I still do not know how to do the communication between the database and the busy.
