        General Definitions of Artifacts
        
        Business artifacts
        provide the mechanism for information localization
        
        An artifact is a concrete, identifiable, self-describing
        chunk of information that can be used by a business
        person to actually run a business.
        
        Business artifacts constitute
        concrete information chunks that the business
        creates and maintains
        
        HR: Artifact identification is as applicable to a specific
        piece of a business as it is to the entire business. Thus,
        if we were to consider the human resources part of
        a business, its key artifact is an “employee record.”
        All the other artifacts within human resources are
        dedicated to support the processing of the employee
        record.
