When you create a class based on QAbstractItemModel, you are the one
who choses what or where is the actual data. Such data can be anywhere
(files, network, in memory variables, etc.). What you do when subclass
QAbstractItemModel is provide to Qt's view classes a way to access the
data for reading, and a way for writing changes back.

Where is your data coming from?
