TAILIEUCHUNG - Lecture Software engineering - Chapter 7: Requirements modeling: Flow, behavior, patterns, and webapps

For some types of software, the use case may be the only requirements modeling representation that is required. For others, an object-oriented approach is chosen and class-based models may be developed. Chapter 7 provides knowledge of requirements modeling: Flow, behavior, patterns, and webapps. | Chapter 7 Requirements Modeling: Flow, Behavior, Patterns, and WebApps Slide Set to accompany Software Engineering: A Practitioner’s Approach, 7/e by Roger S.

Requirements Modeling Strategies One view of requirements modeling, called structured analysis, considers data and the processes that transform the data as separate entities. Data objects are modeled in a way that defines their attributes and relationships. Processes that manipulate data objects are modeled in a manner that shows how they transform data as data objects flow through the
