am a beginner in mainframe.So can anyone tell about the need of having a data set in mainframe?
As the name should hint to you, a data set
holds the data
that your programs will manipulate. They may access that data through interfaces (e.g.
, DL/I, SQL, etc.) that make it look like the data are stored in other constructs, but those logical constructs are all instantiated by data sets.
