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. |
