ADO.NET Overview, Page 4
ADO.NET bundles with a bunch of content components. The most important are:
DataSet — This is a lot like the old Recordset object, except thatit can hold multiple "tables" of data. You can also setup internal dataconstraints and relationships.
DataView — The DataView is similar to a regular database view. Youcan essentially use this object to filter tables inside the DataSet object.
