Dataset: MultiUser Synchronization

[Microsoft]

Hi,
can any one pls tell me how can we use the DataSet in the MultiUser, or else web application, as it is a disconnected architecture.
here is an example:
I have a web App. and many user will be useing the same set of records lets imaging: Railway tickets
when the 1st user picks one record and performing some modification and in the mean while if the 2nd user picks and modifys what is the status of the record.

if i worng in any technical words and if any one didnt understand pls let me know

Hi,

In short words: this is called optimistic concurrency.
The 2nd user should check what's the state of the record (if it matches to the original state) when it is updated.
A perfect column for checking data modifications might be a SqlServer's TimeStamp column.

That's very briefly.
