A Process Oriented Approach to Model Non-Functional Requirements Proposition Extending UML
نویسنده
چکیده
Non-functional requirements (NFRs), sometimes termed quality, or quality of service, attributes or requirements, have been a topic of interest within systems engineering, software engineering, and requirements engineering for a considerable period of time. NFRs have been for too long overlooked during the development of software systems. This has led to numerous cases of failure resulting in over budgeting or cancellation of projects. This paper proposes a method to extend the UML diagrams to model NFRs. A car rental case study is provided to illustrate the use of the proposed method.

Extending Unified Modeling Language to Support Aspect-Oriented Software Development
Aspect-Oriented Software Development (AOSD) is continuously gaining more importance as the complexity of software systems increases and requirement changes are highrated. A smart way for making reuse of functionality without additional effort is separating the functional and non functional requirements. Aspect-oriented software development supports the capability of separating requirements base...
متن کاملMapping Activity Diagram to Petri Net: Application of Markov Theory for Analyzing Non-Functional Parameters
The quality of an architectural design of a software system has a great influence on achieving non-functional requirements of a system. A regular software development project is often influenced by non-functional factors such as the customers' expectations about the performance and reliability of the software as well as the reduction of underlying risks. The evaluation of non-functional paramet...
متن کاملModel-Driven Theme/UML
TTTTheme/UML is an existing approach to aspect-oriented modelling that supports the modularisation and composition of concerns, including crosscutting ones, in design. To date, its lack of integration with model-driven engineering (MDE) techniques has limited its benefits across the development lifecycle. Here, we describe our work on facilitating the use of Theme/UML as part of an MDE process....
متن کاملAspect Oriented UML to ECORE Model Transformation
With the emerging concept of model transformation, information can be extracted from one or more source models to produce the target models. The conversion of these models can be done automatically with specific transformation languages. This conversion requires mapping between both models with the help of dynamic hash tables. Hash tables store reference links between the elements of the source...

Software architecture is one of the most fundamental products in the process of software development in the areas of behavioral or non- behavioral features like availability or transformability change. There are different ways to evaluate software architecture one of which is the creation of application model. An executable model of software architecture is an official description of architectu...
