Which tool is primarily used to design data mappings in Informatica Cloud?

The Mapping Designer is the primary tool used to create and design data mappings in Informatica Cloud. This tool provides a graphical interface where users can define how data is transformed from source systems to target systems. It allows for the configuration of various transformations, including filtering, aggregating, and joining data, to meet specific business requirements.

With the Mapping Designer, users can visually connect different data sources and targets, making it easier to understand and manage complex data flows. This design environment also supports versioning and reusability of mappings, allowing for more efficient maintenance and updates as business needs change.

Other tools, such as the Data Modeler, Workflow Designer, and Process Builder, serve different purposes. The Data Modeler is focused on creating and managing data models rather than designing mappings. The Workflow Designer is used to orchestrate the execution of workflows, which includes sequencing tasks but does not design the underlying data transformations. Finally, the Process Builder is oriented towards building process automation and integration, handling processes and business logic rather than direct mapping of data. Hence, the Mapping Designer is the most appropriate tool for designing data mappings.
