Difference between Procedure create via Modeler and Development ?

Hi to all,

As i know,we can create procedure via Modeler and Development, what the difference between them ?

Please also provide document for same.

Also

If we create procedure via Development perspective in HANA., we can create procedure via below 2 way .

1.  File -> New File-> Procedure name(.procedure)

and

2. Via Stored Procedure (file format (.hdbprocedure)

Both have difference symbols for procedure.

Please can you explain, why this 2 method also in development perspective also ?.

Please also provide document for same.
