I have to design a application (client/server) where server will be sending the data to all the connected client(clients will be connected to server either by TCP/IP or Remoting). The problem here is server has to retrieve the data from the data base and
the data will be changing after every 5 seconds in the database. My questions here is ...
What will be the best approach to establish the connection between client and server i.e: TCP/IP(socket programing) or by using Remoting
How to deal with the database where the data will be changing after each 5 seconds
What is the best why to send the data to all the clients(i.e: convert the database data into xml file or convert the database data into an object )before pushing the data to the clients
The article shows how to do it using duplex contracts, but you can achieve it using tcp/ip sockets too, among others. Have a look at
http://msdn.microsoft.com/en-us/library/ms978603.aspx to know about the publisher - subscriber pattern in general.
If a .NET solution will suffice, then you could use a net.tcp WCF service to have Silverlight clients subscribe to updates being pushed. Have a look at the following for some full examples on doing this:

How is the data changing? Is the same data being modified/updated or is new data being added/deleted?

I don't entirely get your scenario , but I am wondering if you could benefit by implementing some sort of publisher - subscriber pattern. You can see one implementation here at http://nagavitalp.blogspot.in/2011/03/implement-publisher-subscriber-model-in.html

Hope this helps.

Pushing Data to a Silverlight Client with a WCF Duplex Service:

Building and Accessing Duplex Services:

I have seen this in action and it works well vs. brute force polling or something similar.
