Mobile Information Exchange and Integration: From Query to Application Layer

Tran, V.T.K., Wong, R.K., Cheung, W.K. and Liu, J.

    Due to the popularity of mobile devices, more and more commercial applications have been developed on these devices. While commercial applications are mostly backed by relational database systems, numerous database engines have been ported to or built on these devices, for example, SQLite. Since connectivity can be unstable or slow, applications such as iAnywhere have considered o ine operations while data can be synchronized with the database server whenever the devices are online. On the other hand, while Web-based and XML content are very common these days, unfortunately, these mobile versions of database engines failed to fully support them. This paper considers a translation-based method with a decentralised versioning system in place to support o ine operations. Web and XML contents are stored and versioned in a distributed manner and can be synchronized with each other without connecting to a server. The schema of these data can be automatically generated on device. With these schema, a translation engine which allows querying these data using SQL by translating the query to a corresponding XML query is facilitated. We believe this framework support mobile data applications on XML or Web data in a seamless manner. Finally, an initial prototype has been implemented and described in this paper.
