ADO.NET is basically made up of two components such as DataSet and .NET data providers. DataSets are objects that store data in a disconnected cache. The .NET data providers is a collection of components such as: Connection, Command, DataReader, DataAdapter. The Connection object is used to establish a connection between the application and the database. | Session 6 GDI+ Programming Review ADO.NET is basically made up of two components such as DataSet and .NET data providers. DataSets are objects that store data in a disconnected cache. The .NET data providers is a collection of components such as: Connection Command DataReader DataAdapter The Connection object is used to establish a connection between the application and the database. The Command object allows retrieval and manipulation of data in the database. DataReader is used to get the read-only and forward-only data from the data source. DataAdapter is used to fetch the values from the data source to the DataSet and also to update the data source with the values in the DataSet. Review Contd The data in the DataSet is stored in the form of DataTable objects. The DataColumn object defines the columns of a DataTable.

The DataColumn object is referenced by the Columns property of the DataTable. The DataRow object represents the rows of data in a DataTable. DataView acts as a presentation layer for the data that is stored in DataTable. It provides a customized view of DataTable for sorting, filtering and searching data. If the tables that are included in the DataSet have a logical relationship between them, the related records can be made available in another table using the DataRelation object. ADO.NET supports two type of Data Binding: Simple Data Binding - only a single value from a dataset can be bound to any control at a given time Complex Data Binding - a control can be bound to a complete dataset The DataGrid control displays data in a tabular format and optionally supports data editing; i.e. inserting, updating, deleting, sorting and paging.
