PIMs (products, interactions, and mashups) are the building blocks of MDM (Master Data Management). PIMs are the data that is used to populate and manage master data. Master data is a critical corporate asset that needs to be cleansed, standardized, and enriched before it can be used for anything from customer 360 views to product catalogs and pricing. MDM solutions provide the governance and management needed to ensure that this master data is high quality and synchronized across different systems.
