WinBatch / SQL / Timeout

This may just be a general programming / SQL question.

I have a program that initially connects to a db and loads an array from it. After an hour, it connects back to the db and reloads the info into the array.

This program runs on about 25 computers and connects to, obviously, the same db.

Would I get a Timeout error when trying to connect to the db if other computers are trying or are as well?

If it's a dedicated DBMS (eg. mysql, postgres, sql server, etc.), no.

If it's sqlite, which is just a file anyway, yes.
