The point is that I am developing a program that uses mongodb locally as a database.
And what I need to know is if the person who is going to use my program will need to install mongodb on their computer or if on the contrary the mongodb library that is hosted in my program takes care of everything.
On one side is your Java program that connects to the database MongoDB through the MongoDB driver for Java.
On the other hand is the server MongoDB , with the database and collections with the information.
It is necessary that users have access to that server so that your program can connect to it. Otherwise they would have to install a server MongoDB local, on their machines, which would not make sense if the information should be shared among all of them.
