There are two types of catalogs in a WebSphere Commerce system: master and sales. While a master catalog is the CENTRAL location to manage all your store's merchandise and services, a sales catalog is a subset of the merchandise and services found in the master catalog.

Every store in the WebSphere Commerce system must have a master catalog. Only one master catalog can exist at a time, and multiple STORES can share a master catalog. However, you can CREATE one or more sales catalogs for CUSTOMER display purposes. A sales catalog has a flexible display STRUCTURE that allows you to associate products to more than one category, to suit the requirements of your store.
