URLYBird1.3.3 must use 2 tier ?

[mark ken]

my assignment is URLYBird1.3.3, I want to use 3 tier to design my project.
but I just found the requirement document say:
The main architecture of the application must be a traditional client-server system. There are three key parts: the server-side data management system, the client-side GUI, and the network connection between the two.

does that mean I have to use 2 tier structure to design my project.
thank2.

Yes, if 'must' means must and 'traditional client-server' means 2 tiers.

[Ed Tse]

Yeah, why make it more complicated if you don't have to.

[Alan Mc Kernan]

I'm not too sure about that. I'd say you could have a business layer in there if you like'd. Thats what I have done and I have a similar spec to you.

It must be 2-tier, not 2-layer.
What would be a 3-tier architecture?

Just answering myself hehe.
3-tier: data base tier, business tier, interface tier, with two network layers.

Hi,

I also have URLyBird 1.3.3 and I have a "business" tier on the server side.
However, even in network mode, there are only 2 interacting hosts, the host on which the client application is run and the host on which the ONLY server application is run. So you have a client talking to a server.
In that sense it is still a traditional client-server architecture.
It all depends on interpretation.
This has been discussed to great lengths in this thread:
Should lock methods be callable by the client


Regards, Ronald.
