I need to develop 2 applications, one for PalmOS and one for Windows Mobile devices like smartphones and PDAs. I have a website that contains a lot of information. This information can be filtered and the results exported. The filtered results is a list of address and names that a person needs to go to and take a survey. This list needs to be imported to the PDA where the user can then go through the list one-by-one and enter information obtained while at the house conducting the survey. When the worker gets back to his/her computer, the PDA application needs to be able to export a file which can then be uploaded to the website which holds all the information. If it is possible to sync the data directly to the website, that would be great, but the end point is to get the survey results back into the website data. I'm open to ideas on how to do this, either via database on the PDA, textfile, etc. Any additional information that you need, please just ask questions and let me know what details you want.
