Object-oriented requirements modeling based on UML

Provides research into object-oriented (OO) requirements modeling. The proposed OO modeling strategy is based on the semantics and the diagrammatic notation of UML. The semantics of UML formalizes the expression of the user requirements, while the diagrammatic notation also enhances the understandability, traceability, verifiability and modifiability of the requirements model. The ability of the system should greatly benefit the end-users and the analysts who participate in the activity of the whole requirements engineering life-cycle. To demonstrate the viability of the approach, we take an example of a small-byte subscription system.
