Sure. Basically each user would have their own database file generated on account creation. Then in your app, instead of doing something like: connectDB("/path/to/db") you would do: connectDB("/path/to/$user/db") Also, if you needed to query all of your users data in aggregate, you would use the 'ATTACH' capability of SQLite to essentially create a master database. Note that you will need to design your scheme appropriately (thoughtful table/column naming, etc) for this to work well.
