Distributed Tier-ed System.

[Alex Stevens]

Hi All,

I firstly apologies if the subject of my post is off-beam (likely!).

I understand the principles of tiered applications and I've written an
application as such.
I have:

An SQL database
A data layer which provides database connectivity
A Business Object Layer, which for example provides a customer object, and
uses the data layer to get information from the SQL.
A UI which uses the business objects.

Now this works all very well when it's all on the same machine.

My question is, how do I get each component (potentially) on a different
machine on the network, and how do I reference each layer in the parent
layer (ie reference the data layer in the BSO layer?)

Could anybody point me in the right direction?
Is it something to do with COM+ or COM?

Thankyou.

Alex

Hi Alex,

You should look at the .NET remoting or Web Services. The former is more
appropriate when the whole application will be working within a LAN, and the
latter is better suitable for applications or tiers communicating to each
other over the Internet.

There are newsgroups dedicated to both of the topics:

microsoft.public.dotnet.framework.remoting
microsoft.public.dotnet.aspnet.webservices

Hope this helps.
