A DataSet is a collection of DataTables that represent the structure and data of a database. It is a disconnected, memory-resident representation of the database that can be used for data manipulation and data binding in client applications. The other options are used for different purposes in ADO.NET: Command is used to execute database commands, DataReader is used for fast, read-only access to data, and DataAdapter is used to fill a DataSet with data from a data source.
