COMPONENTIZED ORDER ENTRY AND EDITING SYSTEM AND METHOD

Abstract:

A componentized order entry and editing system and method is provided. The functionality of an order model is divided in components each of which execute their own rules independently. A data model is maintained in the form of a set of ledgers, and each ledger includes a complete history of additions and removals from the ledger associated with an order. The current state of the order is obtained by collapsing information in the ledgers. The rules of the components can be triggered in various ways, including user input, workflow, changes to one or more ledgers, and change to collapsed state.
