+We have three helper methods, `fetch_range(class_, range_)` and
+`fetch_all(class_)` are very similar: the former fetches the records
+fetchable from the object id range provided by the user, whereas the
+latter fetches all records. Both return a tuple of `class_` objects.
+
+The last helper method, `fetch_if(class_, condition)` fetches all
+the records of type `class_` that fit a certain condition. Here conditions
+must be written is SQL syntax.
