Towards Use Case and Conceptual Models through Business Modeling

Abstract

Abstract.A guide to requirements modeling is presented in this paper, in which use cases and the conceptual model are directly obtained from a business modeling based on UML activity diagrams. After determining the business processes of the organization, and describing their workflows by means of activity diagrams, use cases are elicited and structured starting from the activities of each process, while the concepts of the conceptual model are obtained from the data that flow between activities. Furthermore, business rules are identified and included in a glossary, as part of the data and activities specification. One notable aspect of our proposal is that use case and conceptual modeling are performed at the same time, thus making the identification and specification of suitable use cases easier. Both use case and conceptual modeling belong to the requirements analysis phase, which is part of a complete process model on whose definition we are currently working. This process is being experimented in a mediumsized organism of a Regional Public Administration.

Transforming the OOram three-model architecture into a UML-based process

“…Figure 7 shows an extract of the glossary. The business rules of the organization [García Molina et al 2000] are also collected in the glossary, which, moreover, allows us to establish traceability relationships between the different modeling artifacts.…”

Application of mobile phone-based system for improved crop production recommendation in arusha, Tanzania

“…The interaction among actors of the system is analyzed by using UML such as a use-case diagram. This labels the expected system functionality from the interactions among external actors and a system (Molina et al, 2000). Table 6 and Table 7 shows the important functionality of the entire application for crop recommendation.…”
