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 :: What Basically Is Factory Design Pattern

Jul 17, 2010

I visited this Link to study about Factory design pattern. 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 ?

Is This Modified C# Singleton Pattern A Good Practice

Feb 9, 2010

I'm developing a blog application shared by non-profit organizations. I want each organization to be able to change their own blog settings. I have taken a singleton pattern (from and modified it. (I understand that it is no longer a singleton pattern.) I have tested this approach and it seems to work fine in a development environment. Is this pattern a good practice? Are there issues, which may arise when this is placed in a production environment?

public class UserBlogSettings
private UserBlogSettings()
public static UserBlogSettings Instance
string cacheKey = "UserBlogSettings-" + HttpContext.Current.Session["userOrgName"].ToString();
object cacheItem = HttpRuntime.Cache[cacheKey] as UserBlogSettings;
if (cacheItem == null)
cacheItem = new UserBlogSettings();
HttpRuntime.Cache.Insert(cacheKey, cacheItem, null, DateTime.Now.AddMinutes(1),
return (UserBlogSettings) cacheItem;

(Portions of code were omitted for brevity.)

Which Pattern Most Closely Matches Scenario Detailed And Is It Good Practice

Mar 6, 2011

I have seen a particular pattern a few times over the last few years. In the UI, each new record (e.g., new customers details) is stored on the form without saving to database. This clearly has been done so not clutter the database or cause unnecessary database hits.

While in the UI state, these objects are identified using a Guid. When these are a saved to the database, their associated Guids are not stored. Instead, they are assigned a database Int as their primary key.

The form can cope with a mixure of retrieved items from the database (using Int) as well as those that have not yet been committed (using Guid).

When inspecting the form (using Firebug) to see which key was used, we found a two part delimited combined key had been used. The first part is a guid (an empty guid if drawn from the database) and the second part is the integer (zero is stored if it is not drawn from the database). As one part of the combined key will always uniquely identify a record, it works rather well.

C# - Find Good .NET Online Tutorials For Web Development?

Feb 16, 2010

I'm a Coldfusion Web Developer and I'm finding that in my local area,work for CF Devs has become extremely scarce.There were a handful of companies that were Coldfusion houses a few years ago and it appears most of them have moved away from CF development.I'm looking to expand my skillset to improve my employment outlook, and it appears that many of the web development positions that are available to me now are focused around .NET web development.The last time i took a look at .NET as a web development platform was way back during 2.0; where I found it to be poorly organized and extremely unfocused.

Apparently somewhere along the line I missed the boat because that's where about 90% of the web development jobs in my area are now.I've done some searching on google to see if I can find a tutorial, something that's akin to hand-holding, and have come back dissapointed.

So I'm turning to the SO community to ask for links and resources that might help better explain how .NET development works in a web development capacity,and for links to these resources so I can begin boning up my knowledge and start writing practice applications.

C# - An Architectural / Looking For Design Pattern ?

Feb 26, 2011

So yesterday my mate and myself had this duscussion about the architecture of this e-shopping website that im developing. Note that I work with ASP.NET for this. He was quite surprised to learn that I do not keep the Items added to the shopping-cart in an ArrayList or other Generic list but rather i insert them straight to the database using LINQ To Entities. Could I pass only for this web app and not use n-tire or should I do as my friend suggested which is, have methods that perform updates, deletions etc..

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

Design Pattern - Rule Checker

Apr 4, 2011

I sell products throgh my website. Recently we've been given a list of rules that need to be checked against each order, to make sure it's not fraudulent. So this list of rules/fraud indicators will change and grow so I want to make sure it's easily maintainable and really solid. I'm thinking I have an abstract class rule that each of the rules implements.

abstract class Rule
public string Message;
public bool Success;
public void CheckOrder(OrderItem currentOrder);
class FakeCreditCardNumberRule : Rule
public string Message = "Fake CC Number Rule";
public void CheckOrder(OrderItem currentOrder)
currentOrder.CreditCardNumber = "1234-5678-9012-3456";
Success = false;
class ReallyLargeOrderRule : Rule
public string Message = "Really Large Order Rule";
public void CheckOrder(OrderItem currentOrder)
currentOrder.ItemsOrder.Count > 100;
Success = false;

Then I'm thinking of having a class that accepts an Order object in it's costructor and checks though the list of rules. Something like:

class FraudChecker
List<Rule> rules;
public FraudChecker(OrderItem currentOrder)
foreach(var rule in rules)

So I was trying to think of the best place/best way to populate the FraudChecker.Rules list and started thinking there might be some nice design pattern that does something like what I'm doing. Has anyone seen a design pattern I should use here? Or can anyone think of a good place to populate this list?

Session Object Design Pattern?

Jan 28, 2011

I'm looking to build an ajax page; it's a reporting page. By default, load today's report. On the page there's a calendar control and when the user clicks on a date, reload the gridview with the corresponding data. Is it considered good practice to do the following:

1) on the first page load, query the data for the page

2) put the query result in the session object and display it in a gridview

3) if the user requests new data, get new data from the query with different parameters

4) put the result of the second query in the session object and display it

5) if the user then requests the data from the first query, get it from the session object

6) do the sorting and paging with the data held in the session.

Note: the data of each query will contain about 300-500 rows and about 15 columns. I'd like to do all this with ajax calls. What are some suggestions and pitfalls to avoid.

So guyz which all popular efficient patterns are there and how would you determine which one suits your app. Can we make a app without a design pattern.

And lastly which one are the most simplest ones out there which are easier to implement.
