Hi,
 I want to save my data on to a Xml file temporarily whenever database connection is not available.Finally read that xml file and store that data in to the database when connection is available.
        Please suggest me in this regard.Expecting quick reply.

Thanks in advance

Okay, so what part are you stuck on? You'll need to devise a suitable XML format that represents your data, check if the connection's available. If not write to the XML. When the connection is available then transfer the XML to the database and deal with any concurrency issues.
