Abstract: Supply chain management (SCM) systems and methods are presented. In SCM ecosystems having multiple independent trading partners that can functions as peers, the trading partners likely lack a “single version of truth” with respect to retail data formats or transactions. The partners can utilize database connectors to interact with other peer partners by converting the partner's retail data from proprietary formats to a common transaction format understood by all connectors or by an SCM application stack constructed from SCM modules. The connectors can use a registry server to discover other connectors capable participating in a requested transaction relationship. SCM modules can be configured to support a transaction relationship according to the transaction relationships available to the peers' connectors.
