Dataset
1. Collection of data table object
2. To populate web server controls
Datasets store a copy of data from the database tables. However, Datasets can’t directly retrieve data from Databases. DataAdapters are used to link Databases with DataSets. If we see diagrammatically,
DataSets < ----- DataAdapters < ----- DataProviders < ----- Databases
DataSets and DataAdapters are used to display and manipulate data from databases.
Data reader
It produce read only and forward only stream that is returned from database.
The DataSet actually uses a DataReader to populate itself. A DataReader is a lean, mean access method that returns results as soon as they’re available, rather than waiting for the whole of the query to be populated into a DataSet.
Data view
Custom view of data table object that are in dataset object
