Abstract: Systems and methods which provide for bidirectional data parity in a multi-service connected environment using a canonicalization and order connection data structure are described. Bidirectional data parity logic using a canonicalization and order connection data structure with respect to a plurality of systems of a multi-service connected environment may provide for the state of a particular order and/or other data for that order being accurately reflected in each such system for which corresponding record is maintained. Using a canonicalization database and an order connection database, bidirectional data parity logic may recognize all records for a particular instance of an order as being for that order, and thus provide data parity for that order throughout all systems having a record for that order instance.

Abstract: Systems and methods which provide for order fulfilment using drop shipping from participating suppliers in an electronic marketplace are described. A drop shipping management system may utilize various rules and information regarding merchants, suppliers, items, etc. in facilitating electronic marketplace drop shipping. Drop shipping management systems may, for example, utilize merchant drop ship rules with respect to merchant drop ship information for determining whether drop shipping is to be provided for a merchant with respect to one or more items in the electronic marketplace. Further, drop shipping management systems may utilize supplier drop ship rules with respect to supplier drop ship information in determining a supplier to provide drop shipping with respect to one or more items in the electronic marketplace.
