Architecture :: Data Transfer Objects (DTO) Design?

Jul 5, 2010

I am currently in the process of creating data transfer objects (DTO) and I am having following queries egarding the same:1. There are some of the Properties of my DTO that will be used only in some places and So in other place it will be an overhead to populate these properties. How should we handle this design problem?2. Should we be including the Aduit information(such as the logged-in person's ID) in the DTO? If not, how do we transfer this audit information between the various tiers of the application?

Architecture :: How To Design Business Objects

Mar 20, 2010

designing Business Objects. What a business object class can contain ?

I have looked many sample codes and articles. Some only use properties in them. Some use private members, properties and constructoers. As more I am reading becoming more confuse.

Some sample codes that I checked were making functions in BO classes as well. what a BO class should contain and what is its purpose. Should there be functions in them as well ? If yes how they can be differentiated from Business Logic class functions.

Architecture :: Using Static Methods To Build User Objects And Various Other Objects?

Jun 21, 2010

firstly a static class only ever exists once and is not an instance. Any static members (ie static int NoOfPeople;) is stored in one place and is shared between all sessions (like the old global variables).
Now static methods is where i'm not 100% sure. If I have a static method that doesn't use any other static members could this cause inconstant results, example (this is a fairly pointless method but just a quick example of the top of my head)

[Code]....

So in this example if two sessions (or threads) were to call this at the same time - would they both get back the expected results, because the method only uses private data (a, b and totalToReturn).Im sure this sounds a little simple but I will be using static methods to build user objects and various other objects that there will have to be a 100% garentee that the objects will not get mixed up between sessions and the wrong things return to the user.

Architecture :: How To Design A Centralized Business Or Service Authentication Architecture

Sep 22, 2010

i 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, 2010

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

Architecture :: Create architecture design For WCF Service?

Aug 10, 2010

I 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.

Architecture :: Maintaining Business Objects ?

Feb 2, 2010

We are using below class(TypeInterceptor) in one of our project to create the instance of business objects.

To Create any business object, we are using the below code

++++++++++

BLayer.TestBO objTestBO;

this.objTestBO = TypeInterceptor.CreateObject<BLayer.TestBO>();

+++++++++++

I think using this kind of creational pattern makes the application not scalable as the same instance will be shared among all the concurrent users.Is it correct?

Is there any better way to abstract the creation and maintaining instance of business objects

Class code:namespace Microsoft.IT.RelationshipManagement.Internal.CISF.Infrastructure
{
using System;
using System.Linq;
using System.Text;[code].....

Architecture :: Passing Objects Between Aspx Pages?

Jan 21, 2010

I have an application that uses DataContracts/DataMembers and Serialization to store information entered in a tab control. There are 8 tabs in the control (therefore 8 aspx pages). The final tab is used to write the information to disk.I am trying to understand: When should serialization be used in a web app? The objects are stored in memory not on disk. Is this another means of passing objects between aspx pages? If so when should serialization be used vs. session objects? How long is the serialized object retained in memory?Can I get a simple example of how to serialize in one page and deserialize the object in another page?I've read many blogs regarding serialization but have yet to find a simple example and none of them explain when serialization should be used vs. session objects?

Architecture :: Looking For Better Way To Design, To Use Object's Properties With The Object Data Source?

May 10, 2010

I've posted the same question in the Object Data Source forum. This is a link to it http://forums.asp.net/t/1554083.aspx. Maybe I should've posted here to begin with. There seemed to be some overlap so I wasn't sure which was the best on to post the question in.

I'm trying to get a better understanding of how I could've designed my app so that the Object Data Source could work with the properties of my business objects. Please read the other post to see how it's currently being done. Sorry for the link to the other page. I didn't want to post a bunch of duplicate information. I would love to get some suggestions for alternative ways of doing this.

Architecture :: Design An Application To Fetch Data From Different Application Databases

Nov 10, 2010

I need to develop an application, which will get records (orders) from one application and process them. The updates to this records (order updates) will be sent back to the source application for end customer reference. I'm planning to achieve this data synchronization at the database level using triggers and stored procedures to insert database between the 2 databases.

But, the issue is I have to deploy this application in 3 different customer sites and I have to change the database names (cannot use the same database name) in each deployment manually. Because of this deployment issue, I was thinking of handling this within the asp.net application where I can store the db name in the database and then build the query within the application, but I dont want to do it as building queries like that doesnt look very professional.

Architecture :: Domain Design Concern?

Mar 20, 2010

All the users of my system get a common Id (SystemUserId). There are predefined roles/groups in the system. One user can be belong one or more of these groups. We are populating the menu/dashboard at runtime according to logging credentials.All common details (properties) of group are stored in main table (SystemUser) and specialized details are stored in relavant tables.(Teacher/Student). My solution already has classes called, SystemUser, Teacher & Student.

Problem:My system should support new group addition. (eg-: Auditor)This should support new properties to be added to SystemUser/Teacher/Student or any other new group added by the Customer at runtime.

Architecture :: Which Design Pattern Can Be Implemented?

Mar 22, 2011

suggest me a good design pattern for implmenting the following? I have an object say myObject. This myObject is created using few inputs from the UI. After the creation of myObject. This object will be passed to few methods.. like method1(myObject);

method2(myObject);... method5(myObject);etc. Each methods will prepare the input for successive methods call. For example method1(myObject) will set the values necessary for the operation of method2.Then method2(myObject) will set up the values necessary for the operation of method3 and so on..Same object is used as the argument for every method calls.Which design pattern can be implemented?

Architecture :: Entity Framework With 3 Layers Design

May 19, 2010

I am thinking to use entity model as DAL, how should I create the BLL then? What kind of datasourceobject should I use in the asp pages?

I am looking for best practice to use Entity framework 2 in the three layers design. I had experience at dataset with three layers design.

Should I use objectdatasource at the pages for gridviews? My guess is that entitydatasource by passed the BLL which is not good, so the only option left is the objectdatasource.

Could and should my BL object inherit those entity model in the DAL, so I dont need to recreate their object's property?
