Sending multiple values in XML to database from application and parse using XQuery in SQL Server 2005
SQL Server 2005 has XML support, it means we can process XML on database side. There are some scenarios that we want to insert, update or delete multiple rows or send some different values to the database, one way is using delimited values and then on database side, we have to parse that string to retrieve the values, another way is using XML to send data to database, then in the stored procedure we can use XQuery and easily parse that XML.(the names are all case sensitive)

When we think about REST web service, we all have heard this recommendation that we had better keep the application state on the client side, if the data regarding to the application state is not that large, then we can put that data in the URI, if you decide to do that to manage the state, then you need to have some kind of checking to make sure that state data has not been tampered. one option is using digital signature.
