System and method for integrating entities via user-interactive rule-based matching and difference reconciliation

1. Technical Field A system and method for integrating entities using a graphic user interface (GUI) to provide user-interactive rule-based matching and difference reconciliation. In one aspect, a system for integrating entities employs a combination of default matching and reconciliation approaches and user tailoring to generate a composite entity from one or more input entities using a set of composition rules. The set of composition rules comprises a combination of default rules, as well as rules that represent user interactions that are performed via a graphical user interface when the user edits a composite result. The rules are captured and then stored persistently when the user requests that the composition be saved, such that the rules may be retrieved during a subsequent editing session associated with the same inputs. If the inputs change, the integration process (as specified by the rules) can automatically handle many changes. It is only when changed elements of the input are, or need to be, subject to specific rules that additional tailoring may be required.
