| Summary: | 碩士 === 國立臺北科技大學 === 電子工程系研究所 === 103 === In recent years, due to searching engines and social networks, the explosive growth of web-related/network-related data lets cloud computing be more popular. Since cloud computing supports parallel processing and high scalability for handling big data, many enterprises are eager to know how to transform the existing SQL data into the NoSQL(Not Only SQL) database. However, there is no any standardized data migration mechanism between SQL and NoSQL. Thus, this paper proposes a bi-directional data migration mechanism (BDMM) between SQL and NoSQL without re-designing the database schema. At the same time, the proposed mechanism is able to improve the access performance. Based on our experimental result, the proposed mechanism promotes 53% access performance.
