A DataReader is a stream of data that is returned from a
database query. When the query is executed, the first row
is returned to the DataReader via the stream. The stream
then remains connected to the database, poised to retrieve
the next record. The DataReader reads one row at a time
from the database and can only move forward, one record at
a time. As the DataReader reads the rows from the database,
the values of the columns in each row can be read and
evaluated, but they cannot be edited.
