Explanation of Mapping, Workflow, Mapplet, and Worklet in Informatica

Mapping

A mapping in Informatica is a set of source and target definitions linked together by transformations to define the data flow from source to target. It represents the data manipulation logic to transform data according to business requirements.

Workflow

A workflow in Informatica is a set of instructions that execute the mapping tasks in a specific order to move data through the ETL process. It includes tasks like session, command, decision, and email tasks to coordinate the execution of mappings, sessions, and other objects.

Mapplet

A mapplet in Informatica is a reusable object that contains a set of transformations that can be used in multiple mappings. It allows developers to define a standard set of transformations and logic that can be shared across different mappings for efficiency and consistency.

Worklet

A worklet in Informatica is a collection of workflows grouped together to form a logical unit of work. It enables the reusability of workflow tasks and helps in organizing and managing complex ETL processes by breaking them down into smaller, manageable units.

By understanding the definitions and purposes of mapping, workflow, mapplet, and worklet in Informatica, you can efficiently design, develop, and manage data integration processes within the Informatica platform.
