Can you explain the difference between an ADO.NET Dataset and an ADO Recordset?

 A DataSet can represent an entire relational database in memory, complete with tables, relations, and views.
 A DataSet is designed to work without any continuing connection to the original data source.
 Data in a DataSet is bulk-loaded, rather than being loaded on demand.
 There's no concept of cursor types in a DataSet.
 DataSets have no current record pointer You can use For Each loops to move through the data.
 You can store many edits in a DataSet, and write them to the original data source in a single operation.
 Though the DataSet is universal, other objects in ADO.NET come in different versions for different data sources.
