As usual determine whether the updated database in the app?

Good
For example, there is a app when you first run it to install the data server and writes to sqlite. After some time, the data on the server is updated. As usual let me know the app that you need to update the table. After all applications have different data (updated when possible, i.e. could get a few updates already), it does not demolish the entire database, but only make up the difference in the data with a server, i.e. to add new data, leaving existing unchanged
