Architecture :: Design An Application To Fetch Data From Different Application Databases
Nov 10, 2010I 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 :: Class Design - Application Allows Admins To Add Types Such As Document Types?
Oct 12, 2010 I have an application that allows admins to add types such as document types and training types that are in seperate tables with a foreign key in a transaction table.
When structuring my class I decided to go with an abstract-like pattern (without the factory methods though). So I have a Type abstract class that defines my Save, Delete, and GetList methods. I have a training type class that inherits this class. The thing is all types have 3 main properties - defined in the abstract base - but have different source tables and thus different store procedures in my DbCommand object. So basically I repeat setting up the same parameters on all the derived classes. I would like to implement the common stuff in the base but I am getting thrown off by the difference in data sources.
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

I would really appreciate if someone could provide me some links and also drop me a few sentences on how this things are useful?
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.

Mar 20, 2010designing 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 :: Domain Design Concern?
Mar 20, 2010All 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, 2010I 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?
Architecture :: What Is The Use Of Aggregates In Domain Driven Design
Aug 7, 2010I want to know what is the advantages of using aggregates in c# for design patterns.
suppose i have tree tables
Member(M_Id,M_Info)
Bid(B_Id,B_Info,M_Id,Item_Id)
Item(Item_Id,Item_Info)
"One member can place more than one bid on more than one item."
so there is one to many bidirectional association between Bid and Member table.
And one to many association between bid and item table Now According to defination of aggregates in this case Item table is the root of aggregate item and item has aggregation with bid table.
and bid table holds unidirectional reference to member table and hence only bid table has access over member table.
But ultimately this will also map in database same as without using aggregate then what is use of aggregates?
Architecture :: What Basically Is Factory Design Pattern
Jul 17, 2010I visited this Link to study about Factory design pattern.http://wiki.asp.net/page.aspx/310/factory/ But i am confused about it still. What i understood is that we must use an Interface to define a class .In the interface we will give the prototype of functions and later on we will define it in concrete class. Is that simple concept is Factory design pattern ?

Apr 24, 2010I have a ordinary Category/Product database relationship Design structure.
Now i wish to add a sub category to this architecture.
for example, Cloths Category needs to be sub divided - Women,Men,Children categories.Also what about other Ctegories such as: Car,this also has sub divisions: Model,Type.
My Products table contains ProductName field together with generic field for Size,Colour and Price fields.
How do you therefore incorporate this sub division into the existing Category/Product relationship model and is there a model example?
Architecture :: Webapplication Design / How To Large Structure
Jul 11, 2010how a large ASP.NET webapplication can be structured / designed with "subwebs" !? In other words I want to structure a large web-application where I have a solution with more web-application projects. These projects are more or less independent "modules". One project should be a kind of frame application with shared masterpages, an shared sitemap and and a shared authentication. Later it should also be maybe possible also to integrate loosely older websites (which where written in classic ASP. ASP.NET 1.1, ASP.NET 2.0), but this not so important at the moment
View 1 RepliesArchitecture :: Overriding Aspx Pages - Best Design?
Jan 25, 2011I would like to provide my client with a aspx pages, with code behind provided, etc. But in some cases they will want to write their own markup - I'm thinking of having 2 directories [siblings of each other], one for the pages I provide, and the other for their custom markup. At page serve time, check to see if the client wrote their own markup and if so use it. Otherwise use the default provided.
In a nutshell I would like for my clients to be able to modify the pages I provide, but if they blow it up have a very easy way to back it out. Or to put it in a more positive light, allow them to override my pages easily.

Architecture :: Design A Class For Product Searching?
Oct 21, 2010I'm refactoring an old website that has product search code littered throught the codebehind. I'm trying to encapsulate the search logic into its own class so I've created a Product class with a Search() method. I would like some suggestions about OO best practices so that the class is reusable and maintainable. The questions I have are:
- Should I make the search() method an instance method or make it static? For now the class is just really there to encapsulate my search logic
- If I make it an instance method should it return a list of products or should it populate a member property that I can access like p.Search(); var x = p.ProductList;
- The search method requires upward of 7 parameters of different types, what's the best way to provide them?
- pass them all i.e. p.Search (param1, param2, ..., param7)
- create a SearchParams structure in the class, populate it and pass that i.e. p.Search(searchParams)
- Instantiate a Product object and set properties on it that are used by the Search method i.e. p.ID = 123; etc.... p.Search();
I've used variations of the above before but would like to know what's the best way.
