Our Canadian client trusted us on Blackberry application development. This application is about rating a room including its housekeeping vendor. Soon after the inspector enters the room, he is able to fetch blank form from the server via his Blackberry handheld, and then report back the review. These results are published on the company website and can be viewed by other users. Interactively, web users are allowed to post comments whether they are agree with the review or not. More conveniently, users also are able to build charts & statistics from these review result.

Interesting experiences:

• Form and data synchronization between Blackberry and web server was a challenge! Users are allowed to choose the form template and how the items are ordered. To fasten synchronization time, only modified data will be synched and the data is compressed to gzip. It took time until we did it.
• Google Chart API to create charts and statistics from survey results. We deliver the results not only on tables but also on intuitive charts. Room owners and users will easily recognize what others think about the room.
