    Question Creating n-tier applications

    Hi guys...

    I'm trying to learn this and had gone through some tutorials (found on googling).
    But most of them are a bit harder to understand. An easy to understand version was not found !

    Do you know any links to a good tutorial ?

    Also, where can I get a good example program written using 3-tier architecture in VB ?

    Any links... ?

    Thanks

    Re: Creating n-tier applications

    Is there a book (from any publishers) completely dedicated to creating n-tier (mainly 3) applications, in VB ?

    Re: Creating n-tier applications

    I would like to echo akhileshbc's question and summon this thread from the underworld if I may? I have been searching all morning through google and amazon for a good logical VB.NET VS2010 web n-tier design guide for slackers like myself to learn such a technology/method.

    Any ideas or suggestions?

    Re: Creating n-tier applications

    Odds are you're not going to... a couple of points... first don't confuse n-tier with n-layers... they are related but different issues all together. You can't have n-tier w/o n-layers... but can most certainly have n-layers but 0-tiers... tiers is a logical separation of the components... data layer... UI, business layer, database, etc... tiered architecture on the other hand is PHYSICAL separation... multiple servers... an app server, database servers, logic servers... the client...
    The other point I want to make is that n-tier is an ARCHITECTURE & DESIGN concept... it's not really a programming concept... while yes as a developer you have to be aware if it's going to be used in an n-tiered architecture, in the end, it doesn't matter much to you... you simply develop the layers... from there if they are all deployed on a single system, a client-server or n-tier architecture, is largely irrelevant.
    That's probably why you don't see VB books on n-tiers... it's a CONCEPT... it affects the design and architecture... it's at a higher level from the development.

    Thank you for the response. I just did some google/amazon searching for "vb.net layered development" and it did not show much of anything.

    What the heck am I not understanding, dangit? lol. What gives?

    Re: Creating n-tier applications

    Not sure if this is what you are looking for or nor.It is an example of an n-tier app I did a few years back. In school it is the only way we were taught to create apps. It is in VS 2005 but it should work. It has a Config File(database path for either an Access DB or SqlServer), a data Access layer, an Entity Layer, Database Layer, a GUI Layer and a Module layer.

    Ok - why resurrect an old thread - you have a web based question - right?

    Thing about web is the UI layer is already a tier - it's running in a browser on a workstation - very much separated from the web server!

    With that said - how are you going to code the frontend UI? Using ASP.Net to "generate" web content on the fly from the backend (yuk)? Using jQuery/Javascript to build the web content in the browser?

    But back to the backend - the web server. Are you going to use IIS to host the service? If you do then every request to the web server creates an independent thread running that functionality. Do you have that functionality talk to another layer that manages the DATABASE ACCESS? I've never seen value to that in a web app - but I'm sure n-tier purists do.

    Are you looking to learn for the purpose of learning? Go to the bookstore and you will find many WROX books on this subject. I've bought about a dozen WROX books in my time and only found maybe one to be meaningful (most are so slanted towards the authors point of view that they are useless in the long run).

    Google for this and you will find many books
