Typed DataSet

Typed DataSet :-
Typed DataSets have all the functionality of DataSets, Typed DataSets directly inherit from the

DataSet classes. Some additional code generated by .NET Framework tools gives all the additional benefits of

Typed DataSets. Furthermore, you can access table and columns by name instead of having to use collection-based

methods with DataSets

-> Typed DataSets check types at compile time it also konwn as This is known as type-safe access
-> automatically complete lines while typing rather the describe each time column name.
