Respected sir,

In 3 Tier architecture,
Can we develop 3 different layers(Presentation layer,Business Layer and Data Access Layer) on separate server ?

If yes,then How can we access it ?
for example if i develop DataAccessLayer on separate server then how can we use this layer into Presentation layer which is on different server ?

Thank you,

Solution 1

For example, DAL could be exposed as a Web Service, or a custom network server, say, based on WCF (self-hosted on the DAL service), TCP (based on System.Net.Sockets.TcpListener, connected to using System.Net.Sockets.TcpClient or using System.Net.Sockets.Socket), and so on.

Sergey, this is the shortest answer posted by you i've ever seen and the longest list of links ;)

Thank you, Maciej. I would not be so sure. And this is certainly not my longest list of links, not at all. The longest one is probably on plug-in architectures... :-)

Not quite sure it's the longest, this is just the first came to my mind...

I must admit I have a lot of duplicates in my links and posted material, just don't bother to filter them. Besides, I'm afraid that some links go, because, if people report some questions for abuse, they are automatically removed with all answers.
