An electronic catalog is provided that stores items and attributes associated with the items. One or more of the attributes may have more than one value. Items are stored in an item table with different attributes for items stored in different rows in an attribute table. Additional items may be added to a catalog by adding additional rows to the item table, with attributes related to the additional items added as rows into the attribute table. Particular attributes may have multiple values, and attributes with multiple values are associated with sub-items that correspond to different attribute trees or attribute sets associated with the item. Searching can be performed for attribute values and search results returned indicating all items and sub-items that satisfy the search criteria.

System and method for storing item attributes in an electronic catalog

Disclosed is method, system, and program for defining and administering a test to determine human perceptions of observable samples, such as printed text or images, sounds, motion pictures, etc. based on multiple factors. A displayable test building window includes input fields to receive input on at least one observable sample set according the multidimensional scaling experiment. Generated in a data gathering window is at least one perception input field for each observable sample set. The observer is capable of entering perception information in each input field concerning the observable samples. Observer perception input on the observable samples is received and stored. Statistical analysis is then performed on the entered perception input. A report is generated displaying the results of the multidimensional scaling calculations in the form of plots.
