What is main use of Mapplet?

What is main use of mapplet? – Mapplets are used to provide the reusable object that is being created by the mapplet designer. – It is used to consist of the designer’s designs that consist of the provision to provide the objects in use. – The mapplet consists of the transformations that allow the use of mapping techniques. – It also reuses the transformation logic that allows the multiple mappings to be done with the source data.

What are mapping parametres and variables in Informatica?

To create parameters and variables in Informatica, you have to follow the predefined syntax and navigation. Mapping parameters are those data types whose value once assigned remains constant throughout the mapping run. Like if you have created a mapping parameter deptno=20, then the value 20 will be constant for the whole mapping run.
