Abstract

Web apps have a problem that they cause same data to be repetitively retrieved, processed, and displayed when web browsers load different web pages. To resolve the problem, this paper presents and evaluates a new method for restructuring of Java web apps. This approach dynamically analyzes Java web apps from the MVC (Model-View-Controller) architecture point of view and identifies redundant data by using the composite view pattern. Then the input apps are restructured in order not to load the redundant data when users make requests for new pages. This restructuring generates new web apps that conform to the MVC architecture and improve the performance of input web apps. The experimental results showed that when compared to legacy web apps, the restructured apps' response time was reduced on desktop PCs and mobile devices by 38% and 55%, respectively. In addition, case studies using open-source web apps showed the applicability of the proposed approach.

웹 앱에는, 서로 다른 웹 페이지를 웹브라우저에 로드할 때 동일 데이터가 반복적으로 획득되고 처리되어 화면상에 표시되는 문제가 있다. 본 논문은 이 문제를 해결하기 위해 자바 웹 앱을 재구조화하는 기법을 제안하고 평가한다. 자바 웹 앱을 MVC(Model-View-Controller) 아키텍처 관점에서 동적 분석하고 컴포지트 뷰 패턴을 활용하여 중복해서 사용되는 데이터를 식별한다. 이를 토대로 페이지 요청 시 중복 데이터가 로드되지 않도록 앱을 재구조화한다. 재구조화를 통해 MVC 아키텍처에 부합하며 성능이 향상된 웹 앱을 생성한다. 이렇게 재구조화된 웹 앱은 기존 웹 앱의 응답 시간을 데스크톱 PC, 모바일 기기에서 각각 38%, 55% 개선하였다. 아울러 오픈 소스 웹 앱을 이용한 사례 연구를 통해 제안하는 기법의 적용 가능성을 보였다.
