As you will probably want to see the data you entered during online session also when you are offline, I suggest the following approach:
1) determine what subset of the remote database you could need when offline
2) add a local database to your application; an embedded one for example, it can be also an other implementation than mysql (google for them, there are many)
3) make your application to work directly in the local database
4) make a distributed transaction based synchronization task/service that will do sync often when online and has the logic to reestablish connection as possible
