INTEGRATED SYSTEM FOR RULE EDITING, SIMULATION, VERSION CONTROL, AND BUSINESS PROCESS MANAGEMENT

System and method for managing one or more rules for use with an application program in a data processing system, the method including:providing an integrated user interface to enable users to interact with an integrated application development system to perform version control and business process management of rulesets, wherein each ruleset includes a set of rule cases that compute values for the rule's output depending on the rule's input, and each rule case includes one or more input relationships in which a rule case is triggered by a given input record if one or more data values of the given input record meet the one or more input relationships;storing multiple versions of a first ruleset in a repository;receiving, through a first interface of the integrated user interface, instructions from a first user; andin response to instructions from the first user,selecting a particular version of the first ruleset from the multiple versions of the first ruleset stored in the repository, transitioning a particular rule in the particular version of the first ruleset from a first state to a second state.
