Catalog+ is the net result of the product information management initiatives, such as Content+ Advanced and/or the Supplier Portal. The purpose of Catalog+ is to have a single, multi-supplier catalog with rich data, searchable attributes, and a consistent commodity schema which can be used to support eProcurement initiatives
Catalog+ puts the horse before the cart - define what you need, then see where it's available. It just makes sense.
All of this is possible because of the initial work that went into building Catalog+:
Clean normalized product descriptions support partial searches, synonyms, and key word
A hierarchical commodity schema supports drill down from top level commodities to the lowest level
Searching on multiple attributes refines a search with thousands of possible items down to a handful
