  2. RQE Modeling Outline • Definition • Conceptual Modeling • Enterprise Modeling

  3. RQE Modeling Definition • A model is a pattern, plan, representation, or description designed to show the structure or workings of an object, system, or concept. And also it is a study of a miniature of the actual [2]. • Requirements models are used when gathering requirements, and during systems analysis. • the importance of correct requirements must be a high priority for you. Building accurate models means that you can guarantee the correctness of your requirements [1].

  4. Conceptual Modeling Definition • An abstract model (or conceptual model) is a theoretical construct that represents something, with a set of variables and a set of logical and quantitative relationships between them [3].
