Dataset is not a contiguous object. It's like an in-memory 
database: tables can added or removed from it, rows can be added 
or removed from tables, fields in rows can be set with various 
values. In the end a dataset is a collection of a big number of 
relatively small objects, big datasets are collections of big 
numbers of objects.
