Dataset is in memory representation of the Database. where
you can create tables, relations between tables, add
primary key to tables and also manipulate the data
retrieved form the database. It allows us to work in
connection less environment.

Datareader is like forward only readonly cursor, which is
used to retrieve data. data manipulation is not possible
while using datareader. datareader continously keeps the
connection open.

Answer / saravanan

dataset is a connectionless service but data reader is a
connection oriented service..

Answer / eduardo belmonte

A ds (dataset) can be used when the connection is closed.
A dr (datareader) needs the connection open to be used.

A ds can be used to modify or delete or insert data in the
database.
A data reader can be used only to read data

A ds can let you access the info on any order at any time.
A dr lets you access the info only one time per item and
only in a sequential order.

A ds data can be loaded in longer time than a dr can be
loaded at.

A ds can contain separated and structured data from several
database tables.
A dr can contain data in one register per item, that
register can include data from serveral tables id the sql
select statement so indicates, but it has no separate
structure per table.
