Methods and systems for database storage allowing subscriber entities to create specialized interfaces for storing different classes of information based on subscribed-defined categories and parameters, allowing for efficient search and retrieval of the information by users using the subscriber-defined categories and parameters. The present technology allows users, such as suppliers, administrators, and others, to add inventory to a database through an interface, search for inventory via an interface, and view results of inventory searches. Inventory requests may be processed using local and remote data stores.
