I've sold a Windows based shareware application using a FoxPro database for years and now it's time to give it much needed RIA. I was excited to hear when Flex 3 was released it supported SQLite, but it's not meant to be a network shared database. My shareware app generally has anywhere from 25 users to 500+ users per network install. The beauty of the current version is it is easy to setup and install, even for non IT users.
What would be the good database to use with Flex or AIR? I could create .Net web services with SQL, but this would take more time to setup and install for potential buyers and of course more support on my end. The install would require the user to setup IIS and SQL. Could be tricky if they don't already have SQL running. I could create a hosted db, maybe something with Google or Amazon, but this would require a large learning curve. Is there anything close to SQLite for networks? Or is there something else I should consider? Any advice or tips would be greatly appreciated!
