In ADO.NET, a DataAdapter functions as a bridge between a data source, and a disconnected data class, such as a DataSet. At the simplest level it will specify SQL commands that provide elementary CRUD functionality. At a more advanced level it offers all the functions required in order to create Strongly Typed DataSets, including DataRelations.
In order to propagate changes back into the database, a DataAdapter object is used that transfers data from between the data source and the DataSet object. Cursors were also deprecated in ADO.NET, being replaced with a DataReader object, which is used to efficiently process a large list of results one record at a time without storing them. [26]
In ADO.NET, a DataReader is a broad category of objects used to sequentially read data from a data source. [1] DataReaders provide a very efficient way to access data, and can be thought of as a Firehose cursor from ASP Classic , except that no server-side cursor is used.
