View 2 RepliesI am using ASP.NET (C# and sql server express 2005) for my web application project. I have three related tables. I want to do an insert using typed datasets,tableadapters and three tier architecture. I wish to know how to do simultaneous inserts in 3 tables. So i wish to insert a row in first table and get its primary key. Same with the second table. I will use the primary keys of those first two tables to do the insert in the third table. How can i accomplish this using formview control and what methods should i use??
View 3 RepliesI am doing a project which requires me to input survey response to database, which means i have to insert data into the table after survey has been attempted.Is there any solutions that i can use to do it in 3 tier architecture?
View 2 RepliesSay you have a form designed in Silverlight(Front end)-Asp.NEt(business layer)-SQl(bakcend)Should data validation occur on all 3 layers or just the presentation layer or a combination of the front end with the other 2 e.g. validating an email address? I'm trying to undestand as to why if data has been validated on the presentation why further data validation would be necessary especially if there would be large amounts of data being validated and this could potentially slow down database transactions?

How can I Edit/Update, Delete and save record to database
recently i've studied on ADO.NET's Entity Model Framework and say 'wow' as ORM is one of the fevourite pattern i practice..but suddenly i've come to an ambiguous situation when i'm going to start. i usually follow the following 3-tier architecture..
1. UI Layer
2. BLL - business logic layer
3. DAL - Data Access Layer
a. DTO / DAO
b. Gateway (contains the sql query/stored procedure and connection with DB)
now when i'm going to use the Entity Model Design,where the DBML/ .edmx File should be placed? Because many a times i'm using the DBML file as DTO because of the mapped objects.. in the same time, sometimes DBML ( .edmx file in .NET 4.0) contains CRUD methods and stored procedured method as well as methods with different selection operations,- which should be in Gateway. so where the .edmx file should be placed !?!! IN DTO namespace !? or in Gateway namespace!
moreover sometimes there is no need for the BLL which breaks the rules of inter-layer-communication (UI > BLL > DAL.Gateway)! what makes me confuse is, what should be the ideal n-tier architecture when i'll use the ADO.NET Entity Model Design Framework
I am working on 3 tier architecture: UI, BL, DAL. In my UI i have following code for Asynchronous page processing:
[Code]....
But I want a database fetch operation to be performed in this asyncronous method. And due to 3 tier arch. i am unable to do this in UI Layer. Can anyone guide me that how can I implement Asynchronous processing in 3 tier architecture? Note: If you are going to place EndAsyncWork1 in DAL then show that how can I return a value back to UI layer from this function.

I want to know that What are the factors if we use methods on each .cs page for connection and executing query on each aspx code behind page rather then using BAL .
How our application get affected in terms of performance and speed or other way?
when we put our website on server after publish/compile in general approach (using query in C# code behind) rathor than using stored procedures?
then which logic is better and why ?

I have implemented the 3-tier architecture project; DAL, BAL, and presentation layer are three layers in it. I am going to implement the following scenario:
Presentation layer calls to a function in the BAL layer which returns 2 string variable, and in turn this function from BAL layer calls to a DAL layer function which also returns 2 string variable. How can I implement the above scenario?
I'm developing a n-tier architecture... I'm confused with handling exception in the layers... Is it a good practise to add a Exception Layer to the architecture.

I was told by my manager that in a few weeks or so we would be getting a bigger project and I need to be well versed with Design Patterns and N tier arcihtecture.
I would really appreciate if someone could provide me some links and also drop me a few sentences on how this things are useful?

I am trying to use a 3-tier architecture (UI, BAL & DAL) for my project. I have each of the tier in different physical machines.
UI - Machine 1
BAL - Machine 2
DAL - Machine 3
How can DAL & BAL interact? What would be the best way to call one component from another?
I was tasked to create 3 tier web application. However, i browsed through many books & tutorials. The examples are doing it using Object data source which my lecturers claimed that it is not 3 tier at all. Shouldn't be dragging any data source into deisgn view. Any comprehensive examples for me to take reference from?
View 4 Repliesi want to develop an application in asp.net using 3 tier architecture .
i know that there are three layers
Data layerBusiness Layer
Data Access LayerBusiness Logic Layer Presentation Layer. I am confused between Data Access Layer and Business Logic Layer.
In data access layer we develop the property classes and main class function which returns datasets, datatables and data reader to Presentation layer.
what is the use of Business Logic Layer ? what actually we do in Business logic Layer
?? we can pass data directly from data access layer to presentation layer ?
i am in the process of creating 3 tier architecture for ASP.net with Microsoft Studio 2005.
My architerture is as below
Presentation Layer Business Logic Layer Data Access Layer
-------------------------- --------------------------- -------------------------------
Form1 BLTable1 DaTable1
(NameSpace = MyCompany.MyProject.BL. BLTable1) (NameSpace = MyCompany.MyProject.DA. DaTable1)
Form2 BLTable2 DaTable2
(NameSpace = MyCompany.MyProject.BL. BLTable2) (NameSpace =
MyCompany.MyProject.DA. DaTable2)
Form3 BLTable3 DaTable3
(NameSpace = MyCompany.MyProject.BL. BLTable3) (NameSpace = MyCompany.MyProject.DA. DaTable3)
I have 2 question here:
(1).MSDN say that we should not have the namespace where its name is same with class name but it does not exlpain why.Does anyone know why? The msdn page is
http://msdn.microsoft.com/en-us/library/893ke618%28VS.71%29.aspx
(2). Business Logic Layer BLTable1 need to interact with Data Access Layer
DaTable1 , so i put the code: imports MyCompany.MyProject.DA. DaTable1 inside
BLTable1, so that i can have access to all the public shared method inside
DaTable1 in BLTable1 for example : DaTable1.Save()
But problem arise when BLTable1 want to use the public shared method in BLTable2 .
I have put the code imports MyCompany.MyProject.BL. BLTable2 inside BLTable1,but i need to
key in the class name twice only can access to the public shared method inside
BLTable2 for example :BLTable2.BLTable2.Save.
