Expanding conceptual models used in information systems analysis with temporal concepts

点击翻译按钮获取中文摘要

In the early stages of developing information systems, systems analysts often create conceptual models. Such models include constructs and rules for describing a domain (usually in graphical form), free of design and implementation concerns. Conceptual models are vital because they help analysts understand user requirements and communicate them to designers. Research shows that understanding user requirements is the key to successful information system design.
