3. The ADO.NET DataReader to retrieve a read-
only, forward-only stream of data from a database. Results are
returned as the query executes, and are stored in the network buffer
on the client until you request them using the Read method of the
DataReader.
Datasets store a copy of data from the database
tables. However, Datasets can not directly retrieve data from
Databases. DataAdapters are used to link Databases with DataSets. If
we see diagrammatically.
Databases  Data Providers  DataAdapters  DataSets

5. DataAdapter is a part of the ADO.NET
Data Provider. DataAdapter provides the communication
between the Dataset and the Datasource. We can use the
DataAdapter in combination with the DataSet Object. That is
these two objects combine to enable both data access and data
manipulation capabilities.
A Data View enables you to create different
views of the data stored in a Data Table, a capability that is often
used in data-binding applications. Using a DataView, you can expose
the data in a table with different sort orders, and you can filter the
data by row state or based on a filter expression.
