Abstract: Abstract of the Disclosure An electronic device is provided. The electronic device includes a display and a processor configured to control the display of a graphical user interface on the display. The electronic device further includes a computer readable medium containing instructions for configuring the processor to provide a menu. The menu includes a plurality of links. The links include at least one link that corresponds to a submenu. The submenu includes a further plurality of links. The processor monitors a plurality of user inputs and monitors the position of a cursor within the display. The processor displays the menu upon entry of a first user input, and displays the submenu upon selection of the corresponding submenu link within the menu. When the cursor is within a content portion of the display and the menu is not displayed, the processor displays the submenu upon entry of a second user input, without first displaying the menu.

Abstract: An arbitrary number of custom catalogs for an arbitrary number of customers can be published from a centrally maintained database of seller catalog data. The custom catalogs are subsets of the catalog database, and are generated in accordance with a set of rules that defines the scope of the content of the custom catalog. The rule sets define a series of sequential searches by which a subset of the item SKUs contained in the database are returned. For extranet buyers, the subsets for each rule set are maintained in a subset table. Whenever a user authorized by a particular buyer wishes to browse the unique catalog subset assigned to that buyer, any queries regarding the catalog will result first in a search of the full catalog database, and the results from the full search are pared down to only those items the SKUs for which have entries in the subset table associated with the buyer's assigned subset.

Abstract: A logical and constraint-based hierarchical approach provides a highly flexible and expressive way in which to browse items stored in a database. The logical and constraint-based approach permits a user to create an arbitrary number of hierarchical representations of the items in a database. The approach permits items to be logically grouped on one level and grouped based on attribute/value constraints on the next. The hierarchical representation consists of nodes that are related to one another in a tree-like structure starting with a root node. Each node has a unique label, preferably indicative of the items in the database that it represents. Each node has a list of the labels of the nodes that are its children. Each node can only be the child of one parent node. Nodes may optionally express constraints based on attributes and their values that serve to define the scope of database items that fall under the node in the hierarchy.

Abstract: A maintenance tool is used to import and centrally maintain the data and metadata representing catalog items in a catalog database. The maintenance tool is further used to create and maintain constraint-based rule sets defining custom catalogs that are subsets of the items in the database, constraint-based pricing profiles that define custom pricing schemes to be applied by the items in the database, and a primary browse hierarchy that represents the items in the database. The maintenance tool is used to create and maintain accounts for organizations and to assign to each organization a custom catalog and a pricing profile. The maintenance tool republishes the data on a periodic basis to update the custom catalogs and pricing profiles based on additions and modifications to the database, the rule sets, and the pricing profiles, and to generate new custom browse hierarchies from the primary hierarchy.
