Answer / ajalali
A mapping parameter is set at the mapping level for values
that do not change from session to session for example tax
rates.
Session parameter is set at the session level for values
that can change from sesion to session, such as database
connections for DEV, QA and PRD environments.
The database connection session parameters can be created
for all input fields to connection objects. For example,
username, password, etc.
It is possible to have multiple parameters at a time.
The order of execution is wf/s/m.

Answer / sasmita panda
If we need to change certain attributes of a mapping after
every time the session is run, it will be very difficult to
edit the mapping and then change the attribute. So we use
mapping parameters and variables and define the values in a
parameter file. Then we could edit the parameter file to
change the attribute values. This makes the process simple.
In a mapping parameter we need to manually edit the
attribute value in the parameter file after every session
run
Session parameters are like mapping parameters, that
represent values you might want to change between sessions
such as database connections or source.
Yes it is possible to create 3 parameters at a time.

upto my knowledge, performance wise mapping parameter is
best to use, but according to requirement you can override
the mapping parameters by workflow variable(to know more
about this you can just check the workflow properties) and
session parameters are just database connections....
correct me if i am wrong.
