The DataAdapter uses the Connection object to connect the data source and up to four Command objects to retrieve data from and resolve changes (i.e., update, insert, and delete rows) to the data source. The DataAdapter also updates the data source with changes made to a disconnected DataSet. DataAdapterīridges the connected classes with the disconnected classes by retrieving data from a data source and filling a (disconnected) DataSet. NET Framework data provider for SQL Server includes the SqlDataReader object. The DataReader object is specific to the type of data source-for example, the. Retrieves a forward-only, read-only data stream from a data source. NET Framework data provider for SQL Server includes the SqlCommand object. The Command object is specific to the type of data source-for example, the. The CommandText property of the Command class contains the SQL statement, stored procedure name, or table name executed at the data source. Issues database commands against the data source using an established Connection. NET Framework data provider for SQL Server includes the SqlConnection class. The Connection object is specific to the type of data source-for example, the. A Connection specifies necessary authentication information needed to connect to a data source. A brief description of each follows:Ī unique session with the data source. The disconnected classes let you access and manipulate offline the data you retrieved using the connected classes and later synchronize it with the underlying data source using the connected class.Įach data provider is responsible for implementing the connected classes.

NET Framework 1.1 or later will run on later versions of the. ADO.NET is based on a disconnected architecture with tight XML integration and is designed specifically to facilitate development of loosely coupled solutions.ĪDO.NET code is forward-compatible-ADO.NET code written using. You can also develop your own data provider to access proprietary data sources or to meet special requirements.ĪDO.NET is fundamentally different from ADO despite sharing a similar name.

NET data provider uses the ODBC drivers to access most ODBC data sources. NET data provider allows access to most OLE DB data sources through OLE DB providers. In addition to database-specific providers, the OLE DB. Since a data provider needs only to implement a core set of standard interfaces, the capabilities and performance of data providers for the same data source can differ significantly. Database-specific providers usually access the underlying data store directly and offer the best performance, broadest functionality, and support for database-specific features. Data providers also exist for databases such as Sybase and MySQL. Other providers are also available for example, Oracle has developed its own.
