초록
IT 기술 및 비즈니스의 급속한 발전에 따라 새로운 서비스를 고객에게 제공하기 위한 노력이 증가하고 있으며, 신속한 서비스 제공을 위해 기존의 레거시 시스템에 대한 개선 및 확장이 빈번히 발생하고 있다. 이로 인하여 기존 레거시 시스템에 대한 소스 코드의 품질 확보는 서비스 요구에 신속히 대응할 수 있는 핵심적인 기술 요소가 되었다. 리팩토링은 기존 레거시 코드에 대한 품질을 확보하기 위한 공학적 기술로서, 부가가치를 제공하는 레거시 시스템의 개선 및 확장에 필수적이다. 본 논문에서는 레거시 시스템의 소스 코드 품질 향상을 위한 기존의 리팩토링 기법과 지원 도구에 대한 조사 분석을 통해 리팩토링 기법과 도구에 대한 특성을 제안한다. 제안하는 특성을 기반으로 서비스 개발자가 레거시 시스템의 소스 코드 품질 향상을 위하여 리팩토링을 수행하고자 하는 경우, 어떠한 기법과 도구를 활용할 것인가에 대한 가이드라인을 제공받을 수 있다. 이를 통해 보다 정확하고 시행착오 없는 레거시 시스템의 소스 코드 품질을 향상시킬 수 있으며, 새로운 서비스에 대한 신속한 대응도 가능하게 될 것이다.
Abstract
Along with the rapid development of IT technology and business services, the effort to provide new services to the customers has been increasing, and also the improvement and enhancement of legacy systems are continuously occurring for rapid service delivery. In this situation, the quality assurance of the source code for the legacy system became a key technical elements that can quickly respond to the service needs. Refactoring is an engineering technique to ensure the quality for the legacy code, and essential for the improvement and extension of the legacy system in order to provide value-added services. This paper proposes some features of refactoring techniques through surveying and analyzing the existing refactoring techniques and tools to enhance source code quality. When service developers want to refactor the source code of the legacy system to enhance code quality, our proposed features may provide with the guidance on what to use any technique and tool in their work. This can improve the source code quality with correct refactoring and without trial and error, and will also enable rapid response to new services.
