Modeling is increasingly used in business, industry, and commerce to develop a common understanding of processes, functions, activities, and supporting data. Typical users of such models are systems developers, operations researchers and business analysts, educators, and executives.Information models are regarded widely as beneficial by saving cost through realignment of processes, risk reduction and elimination of redundancy. Information models convey ideas and facilitate the analysis and understanding of complex processes and structures. These models form the basis for software engineering practices that build systems and databases, redefine organizational structures, improve business processes, and develop standards.This practice provides a practical means for developers and users of information models to employ appropriate modeling methods and to objectively determine model quality.
