business layer, data access layer , presentation layer for asp.net using C#.nethello everyone
i have got a problem i want to design business layer, data access layer , presentation layer for asp.net using C#.net , can anyone help me to solve this problem. i want some resources to complete this. i am trying very hard. Do you have any idea about website or any links where i can find some examples based on this concept.can you plz provide me , its urgent i want this solution with an example, if u have plz provide me. Thanks in advance Dhananjay First, don't post a C# question in a VB newsgroup.
Second, check out Rockford Lhatka's books.

Sounds like the
problem is someone told you to do something that you have no idea what it even means. Try Model View Presenter, Model View Controller, asp.net Facade pattern The book suggestion is also valid as it is written for both VB and C#. You just select your poison when you buy it. But it is Business Objects, not data objects. What are you defining a business and data layer as? From my experience, 95% of people that talk about it, know the buzz words, but do not know what they mean or how to do them. And, creating strongly typed datasets in VS is not a data layer, just to give you a hint. I have written what I consider a real data layer and business layer in both VB and C#. I have yet to find a good model of any of the 3 I told you about above that was presented to do anything other than display data. So I have to say, I lack what most would consider a "real" presentation layer that is independent of the form/view. I am working through the Business Objects for VB book currently to see if I can get past that problem. Oh, another source, is the microsoft patterns and practices web site. If you download and use the enterprise library, you will have 1/3 of the data layer done for you. Good luck. You are going to need it.

Take a look here. There is a complete set of tutorials discussing your issue. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaspnettut/html/aspnet_tutorial01_dataaccesslayer_vb.asp The tutorial is written for VB, but most of it should simply be syntax changes.

What you did not bother to tell the poor guy is that it is using stronly typed datasets. If he does that and the location of the data changes, he gets to recreate his entire "data layer." That is just one of the reasons that I do not consider strongly typed dataset as a REAL data layer. You should not have to recreate the entire thing if the location of you data source changes. So why not do it correctly the first time instead of doing it over and over again? Do stored procedures in the SQL database for CRUD (CREATE, READ, UPDATE, DELETE). (I am assuming that he is using a real database at this point.) Use the enterprise library to get the methods you need to execute the stored procedures and get the data into either a dataset or datareader. Write a class that encapsulates this functionality that the business layer can call WITHOUT knowing anything about the database. Now, you have a real data layer and not a hack job. Now you also see why I consider the enterprise library to only be 1/3 of the data layer. Robert P.S. There are also video presentations of what you gave to him, and more, on the Microsoft site with code examples in both VB and C#. Bruce W.

Allow me to preface my following comments with the information that I am a totally fledgling hobbyist programmer at the moment. I am attempting to learn this language on my own and have yet to advance my programming capabilities to the point where I would recognize a 'strongly typed' anything other than to assume it's something in BOLD TEXT. hehehe My apologies for not being more forthcoming with any other information, but he had asked for a nudge in the proper direction and I remembered those tutorials from when I first installed the software and noting them on the News portion of the start page. Secondly, I thank you for the information that you have given me. Should I advance to the point where I can use the information you have provided, I shall be that much further along than I am at this point. And he should be able to see your warnings to me at this same time, so he has garnered double the information.
