An electronic commerce system includes one or more databases operable to store product data for one or more products. The system also includes a master global content directory that includes a plurality of product classes organized in a hierarchy, the product class categorizing the products and associated with one or more attributes of the products. At least one of the product classes has one or more associated product pointers that identify one or more of the databases. The system further includes one or more secondary content directories including one or more classes mapping back to the product classes in the master global content directory and the classes having associated class pointers that identify product classes in the master global content directory. The system also includes a search interface that communicates a search query to one or more of the databases to search product data.
