An object-oriented product configuration system generally includes a model tool for modeling a particular product line and a runtime tool for making the modeled information available to one or more external software applications. More specifically, the model tool enables a modeler to create a ProductModel object, which is an automatically populating electronic file containing all of the necessary information about a particular product line. Once the ProductModel is created, the runtime tool provides an external application with an interface for accessing and utilizing the information. Thus, a single source can deploy useful information to various types of software applications.
