Can you explain CSDL, SSDL and MSL section in EDMX file?

CSDL (Conceptual Schema definition language) is the conceptual abstraction which is exposed to the application.

SSDL (Storage schema definition language) defines the mapping with your RDBMS data structure.

MSL ( Mapping Schema language ) connects the CSDL and SSDL.

CSDL, SSDL and MSL are actually XML files.
