State the difference between mapping parameter and mapping variable? |
|
Answer» Mapping Parameter: Mapping parameters in Informatica are constant values that are set in parameter files before a session is run and retain the same values until the session ends. To change a mapping parameter value, we MUST update the parameter file between session runs. Mapping Variable: Mapping variables in Informatica are values that do not REMAIN constant and change throughout the session. At the end of the session run, the integration service saves the mapping variable value to the repository and uses it for the next round of SESSIONS. SetMaxVariable, SetMinVariable, SetVariable, SetCountVariable are some variables functions used to change the variable value. |
