Abstract
Quality of Service is an important attribute of a software system. In retrospect, performance assessment based on user interaction with the system has given a better understanding of underlying disciplines of the product. In this paper, we capture user interaction with the prototype/User Interface (UI). An approach for developing activity model from the user interface model is presented using workflows and functional elements. A methodology is proposed to transform UI into activity diagram. The approach is validated by an experimental setup using Amazon service. The performance of Amazon service is assessed using activity based performance prediction methodology, and the simulation results are obtained using SMTQA.
Highlights
Web services are software components that provide flexibility to operate between different applications through the Internet [1]
Performance is an essential attribute to be assessed for web applications/web services (WA/Web services (WS)) of all the other quality attributes
The methodology proposed in this paper provides guidelines for generating activity models from user interfaces with the help of workspaces
Summary
Web services are software components that provide flexibility to operate between different applications through the Internet [1]. Performance plays a significant role in achieving the Quality of Services (QoS) of web services. Every aspect in the analysis, design, code, and deployment of web services has an impact on its performance. It is difficult to understand the complexity at a given point in time. Performance is an essential attribute to be assessed for web applications/web services (WA/WS) of all the other quality attributes. The customers or users of the software expect the web services to respond fast as they don’t want to wait for a long time
