Can anyone speak to how well these different options work when part of your data collection is still done by hand? While eventually we might move all surveys to mobile collection, the transitional period would likely include both paper and mobile collection. How easy is it for this data to be consolidated (off-line) in a database and then accessed and queried through the cloud when internet access is available? To the latter point, what solutions have folks used as the backend for both database management, data visualization, report customization, etc.?
