Data Flow Diagrams versus Use Cases - Student Reactions
نویسندگان
چکیده
Data Flow Diagrams and Use Cases are two popular methodologies in teaching as well as in practice. We recently used both methodologies in teaching four sections of our required Systems Analysis course. Questionnaire results indicate that students prefer Data Flow Diagrams.

متن کاملA Knowledge-Based Method for Inferring Semantic Concepts from Graphical Models of Real-time Systems
Designers of software for real-time systems often use models, in the form of data flow/control flow diagrams, to express system behavior in a graphical notation that can be understood easily by users and by programmers, and from which designers can generate a software architecture. The research described in this paper is motivated by the desire to provide an automated designer’s assistant that ...
متن کاملAn Automated Approach to Transform Use Cases into Activity Diagrams
Use cases are commonly used to structure and document requirements while UML activity diagrams are often used to visualize and formalize use cases, for example to support automated test case generation. Therefore the automated support for the transition from use cases to activity diagrams would provide significant, practical help. Additionally, traceability could be established through automate...
متن کاملThe REA Ontology to Supplement Teaching Data Flow Diagrams
Systems Analysis and Design is a core component of most information systems curricula, and generally includes coverage of process modeling with data flow diagrams. In order to relate process modeling to something with which all students are familiar, the content of a traditional Systems Analysis and Design course can be supplemented with an ontological framework. This manuscript proposes that a...
متن کاملControl-flow semantics of use cases in UML
1 The control-flow for five kinds of use cases is analysed: for common use cases, variant use cases, component use cases, specialised use cases and for ordered use cases. The control-flow semantics of use cases – and of the uses-relation, the extends-relation and the precedesrelation between use cases is described in terms of flowgraphs. Sequence diagrams of use cases are refined to capture the...
