How many dataBase tables can a dataSet table update via dataGrid?

[Gary Frank]

I would like to display data in a datagrid in which the source of the
data is multiple database tables. The select statement in the command
object that is a property of the dataset selects from multiple database
tables. The dataset table therefore contains data from multiple
database tables. This dataset table is then bound to a datagrid. Is
it possible to update the database tables that are the datasource by
using the edit, update, delete buttons of the datagrid? Or can you
only update the datasource of a datagrid if it contains only 1 table?
