Abstract

This research is a byproduct of a project initiated by a major airport in Korea. The airport aimed to enhance airside safety and weighed a few IT options that may strengthen its current safety practices. In order to satisfy requirements unique to the airport and to inherit existing legacy systems, a PCS-based mobile database system was proposed. We first discuss technical aspects of the system as well as design issues in mobile systems before we compare two specific alternatives for transactional service handoff. A simulation study comparing two types of coordination follows before we present a scheme that manages transaction processing and locating service in mobile environments. Finally, we discuss the limitations of the scheme from the perspectives of the airport in question along with other research issues.

이 연구는 한국에 위치한 어느 공항의 프로젝트를 수행하는 가운데 도출된 결과다. IT 솔루션들을 놓고 검토한 결과, 레거시 정보시스템을 흡수하며 동시에 안전 수준을 향상시키는 시스템을 구축하기 위해서, PCS에 기반을 둔 모바일 데이터베이스 도입을 고려하면서 동반되는 물리적인 제약과 기술적인 문제들을 검토하고, 모바일 환경에서의 트랜잭션을 처리해 주는 두 가지 선택에 대하여 비교한다. 현재까지 알려진 문헌연구와 시뮬레이션 스터디를 통해서 이들 기술을 비교한 다음, 트랜잭션 프로세싱코디네이터 마이그레이션에 대한 방법을 제시하며, 기술이 가진 한계를 현실적 환경에서 검토해 본다.
