.NET
is widely used in application development. .NET language has various
features and methods for dealing with data. Let us look at a few.
Data Provider
A .NET framework data
provider is used for connecting to a database, executing commands,
and retrieving results. Those result are either processed directly,
placed in a dataset in order to be exposed to the user as needed,
combined with data from multiple sources, or remoted between tiers.
.NET framework data providers are lightweight, creating a minimal
layer between the datasource and code, increasing performance without
sacrificing functionality.
Data Reader
Data reader object is a
stream-based, forward only, read only retrieval of query results from
the data source, which do not update the data. The data reader cannot
be created directly from code, they can be created only by calling
the execute reader method of a command object.
Data Adapter
Data adapters are an
integral part of ADO.NET managed providers, which are a set of
objects used to communicate (bridge) between a data source and a
dataset. Data adapters are used to exchange data between a data
source and a dataset. Two methods are used in data adapter
Fill () - to fill data
from data adapter to dataset
Update () - to commit the
changes made in dataset to the database
FillSchema () - to fill
data from DataTable to dataset
