I am developing an AIR desktop application for a Windows 7 touch screen kiosk that needs to access and allow users to search a set of data, which could initially contain anywhere between 17,000 and 100,000 records. Each record could have perhaps 15 to 20 fields, and all the data will be stored locally on the computer, and updated with new data by memory stick, perhaps once per month. The kiosk will not be connected to the internet.
Can anyone offer any advice as to the viability / limitations of using XML, SQLLite, or some other means of data storage, to access this information from an AIR application?
