Which term is defined as a methodology for developing an integrated information system based on the sharing of common data, with emphasis on decision support needs as well as transaction-processing requirements?

• A. Project Management
• B. Digital Engineering
• C. Information Engineering
• D. Operations Research

Answer: (C)

Information Engineering is a data-centered methodology for building an integrated information system around shared, common data. It starts from an enterprise data model that captures the business data once, with consistent definitions and structures that can be used by many applications. This shared data foundation supports both transaction processing and decision-support needs, ensuring that reporting and analysis see the same information as operational systems. By emphasizing data modeling, data architecture, and process alignment, Information Engineering delivers an architecture where applications share conformed data, reducing redundancy and inconsistencies. This approach, developed to bridge operational systems with analytical needs, stands apart from general project management, traditional engineering methods, or optimization-focused disciplines.
