Informatica developers analyze a business's database storage and warehousing capabilities and assess the company's data requirements.

Mapping in Informatica is a collection of source and target objects linked together by a set of transformations. These transformations consist of a set of rules, which define the data flow and how the data is loaded into the targets.

Data mapping is the process of extracting data fields from one or multiple source files and matching them to their related target fields in the destination. Data integration or ETL mapping helps consolidate data by extracting, transforming, and loading it to a data warehouse. The initial step of ETL is data mapping.
