.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
