Help on 3Tier Programming...

[TLiberty]

I'm learning VB6.0 and would like some explaination on 3Tier, mainly, a simple algorithm/pseudocode (if possible sample code) on how to implement a project with the use of 3Tier.<br>

The task you ask is no small undertaking... There is a thread in the 'Microsoft: DCOM' section called &quot;Anybody out there interested in talking about MS multitier dev issues?&quot; This is an excellent thread that John started several months back. There was a ton of good input from users here that are blazing new ground in this arena. I suggest you start there and then move on to some of the books that are referenced in the posts. I think this is one of the best places to start to try to learn what you're asking.<br>

Your best bet is pick up a book or two on the topic. Two books that are popular:<br>
<br>
&quot;Visual Basic 6 Business Objects&quot; by Rockford Lohtka, Wrox Press<br>
<br>
&quot;Doing Objects in Microsoft Visual Basic&quot; by Deborah Kurata, Ziff-Davis Press<br>
<br>
Basically, 3-tier development is not so much about algorithms and logic as much as it is about the distribution of them. For example, in a simple VB program, you might do your data access, business rules validations and the user interface all in the same program. In a 3-tier environment, these three areas would be separated into three projects. It is very powerful and flexible and in a way improves your design process as it forces you to think about all aspects of your project prior to implementing it.<br>
<br>
I've been blessed by arbitrarily picking Lohtka's book and it has been great. If you go that route then make sure you also pick up &quot;VB 6 Distributed Objects&quot; which I consider to be a must.<br>
<br>
Deborah Kurata has a very nice website but I can't remember the URL. May be someone else can post that here.<br>
<br>
As Steve mentioned, this topic has its own forum, Microsoft: DCOM. There is a lot more information in there than you'll find in this forum.<br>
<br>
Good Luck!<br>

Thanks, I'll do the research as suggested.
