Architecture :: Website That Work A Lot With The DB - The Best Way?
May 22, 2010I'm in the middle-end of written a big website that work a lot with the db.
In every call a page runs 5-12 different queries.What I did was build an execute class that uses MySqlConnector API, which get string that represent the sql and the parameters and then just execute the query and return DataTable. In addition to that I have a class that hold all the function that call the execute class functions. For example in the class I have getAllProducts, getOldestProducts etc... and in each and every one of them theres sql statements.
Recently I watch the LINQ video series(How Do I with LINQ - on this site) and it looked good.As I sees it my way is very good because it just open connection execute the sql get the result and close the connection.The question is what is the best performance wise way to build this site? Is it my way that I use all along? Is it using LINQ? Or working with DataSet/TypedDataSet is the preferred way?

Architecture :: EF4 With Repository And Unit Of Work Patterns?
Sep 26, 2010I've been reading recently about EF4, and how to build an architecture for asp.net web forms application using it.
I explored using POCOs (self tracking entities), with WCF, but found out that my application will be deployed on a single box (i.e. one tier), so I started reading about logical separation of layers, and came up with the following solution:
DAL layer that contains EDMX model and EF APIs, and also generated context object.Entities DLL that holds all generated POCO entities using ADO.NET POCO entity generator. (for persistence ignorance, and decoupling entities from DAL).Business layer that contains a façade for each related group of business functions, the façade will be aware of and using DAL layer. And in each function, it will initiate context and uses different entities to carry out specific job (i.e. function).UI layer that only calls the business layer façade classes. With no awareness of DAL, but it will be aware of entities (i.e. using entities DLL), as the business layer will return results basically as entity collections.
I want to know what you think about this architecture.
I also read about an architecture that uses repository and unit of work patterns, but what I understand that context object is already implementing a UOF pattern, and also object sets are implementing repository pattern (correct me if I'm wrong), so the only advantage of using additional abstraction over them is to make the business layer communicates to my classes, not EF classes, and this is good only if the DAL strategy might change (i.e. by using another tool other than EF, which is not my plan).

Architecture :: How To Design A Centralized Business Or Service Authentication Architecture
Sep 22, 2010i want to create a centralised business or Service authendication architecture in .net. for example, we have a clients like c1, c2, c3, c4, ... etc. everybody logins seperatly as well as grouply. ie, if client "C1" logins [with login authentication] he can access c2 , c3, c4 also without login authendication. So its like a google. if we enters gmail account, we can access orkut, picasa like that.. i need the cetralised architecture.
And, client "c1" seperately asks seperately how will be the authendication architecture.
so give me the single solution for both these two scenarios. how will be the architecture for these two and how is the Data Base (Login) Structure.
Architecture :: Entity Model Design Framework And N - Tier Architecture
Dec 25, 2010recently 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
Architecture :: Asynchronous Page Processing In 3 Tier Architecture?
Jul 30, 2010I 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.

Architecture :: Function Implementation In 3-tier Architecture?
Apr 28, 2010I 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?

Architecture :: Create architecture design For WCF Service?
Aug 10, 2010I am try to create architecture design for WCF service.
We have WCF service that we have to expose to third party so then can request with xml and get back xml response.
The wcf service should do the following:
- Accept the request call with xml
- Check xml against the schema
- Parse the xml
- Authenticate the incoming xml by username and password that will be in xml
- Send back the response
If anybody can let me know what kind of design I can use or is there any pattern available that I can take it and then extend it as per my requirement.

View 4 RepliesArchitecture :: How To Develop An App Using 3 Tier Architecture
Aug 18, 2010i 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 ?

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.
