碩士 === 長榮大學 === 經營管理研究所 === 92 === Working in mobile environment has become more and more popular recently. With intermittent connection to data server, users often download part of data items to the local device and operate them during the disconnection period. If the data items they modified are shared, then it is quite possible that some conflicts will occur among them. This study focuses on how to ensure the rule of serializability among client transactions. Two concurrency control protocols with client-server environment are brought to our attention. We verify their correctness and analyze their characteristics, and then suggest some applicable areas for them accordingly.
