Offline Database

Hi guys, I currently implement a 3-tier architecture application over the Internet. But I am having a difficulty, if in case that there will be no internet connection, the company goes back on the manual operation meaning, they have to make use of paper and pen to record transaction. And so, I am planning to create an Offline DB in case that there is no internet connection. However, I don’t know how to dump the data of the Offline DB to the Online DB. Can anyone give me an idea or a site that will teach me how to address this kind of difficulty, please help me.

Microsoft Sync Framework.

Never used this… realy don’t know if its a good solution or not, but seems to fit your problem.
