There are three most commonly used methods of Dataadapter
Fill :- Executes the SelectCommand to fill the DataSet object with data from the data
source. It an also be used to update (refresh) an existing table in a DataSet with changes
made to the data in the original datasource if there is a primary key in the table in the
DataSet.
FillSchema :- Uses the SelectCommand to extract just the schema for a table from the
data source, and creates an empty table in the DataSet object with all the corresponding
constraints.
Update:- Calls the respective InsertCommand, UpdateCommand, or DeleteCommand for
each inserted, updated,or deleted row in the DataSet so as to update the original data
source with the changes made to the content of the DataSet. This is a little like the
UpdateBatch method provided by the ADO Recordset object, but in the DataSet it can
be used to update more than one table.
