Difference between dataset and data table

DataSet and DataTable are the key components in ADO.NET programming. This mean that DataTable represents an in memory representation of the database. We can load a single Table from the database into a DataTable and manipulate the data in memory. DataTable can be used as a DataSource and used it if we are going to fetch data in a single database table only. While DataSet on the other hand can define DataRelations - which define the relationship between DataTables, much like a foreign key relationship can be set up between tables in a database.
