Architecture :: Implementation Of User Authentication In C#?

Feb 15, 2011

I am working on a web application project with a layered architectural style having DAL, BLL, Service Layer and Presentation Layer. It's going to be a Web forms application.

My intent is to try using some of the new features of .Net 3.5 or 4.0.

Currently, I am thinking through different approaches for implementing Authentication in this project.

I have a query regarding the design of the application, particularly Authentication.

In which layer should I have Authentication class? BLL? If I implement the Authentication class in BLL, should I be having an app.config in the same class library project to contain the Database connection string and all.

Architecture :: Function Implementation In 3-tier Architecture?

Apr 28, 2010

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?

Architecture :: A Proper DI Implementation?

Feb 27, 2011

I'm fairly new to dependency injection but it seems like a proper DI implementation will be fairly complex.

For example, DI requires a centralized class that manages the configuration and resolves the dependencies at runtime.

DI is also based on the concept of using interfaces. For example, a SpecialLogger should use an ILogger interface.

The centralized DI manager class will need to register types - for example, associate ILogger to SpecialLogger.

SpecialLogger will also need to implement the ILogger interface so SpecialLogger can be used through the DI ILogger interface.

Therefore, it seems like a sln using DI will need multiple projects to support DI. Here is an example for logging:

* MyCompany.MyDivision.Framework.DI.Management - this would have the DI manager where dependency types are registered and resolved at runtime
* MyCompany.MyDivision.Framework.Logging - this would have the implementation of a logging class. The main logging class would need to implement ILogger.
* MyCompany.MyDivision.Framework.DI.Interfaces - this would have the ILogger interface.

Interfaces would need to be stored in a separate class library from the DI manager because both the DI manager and SpecialLogger use the ILogger interface. Since the DI manager associates SpecialLogger to ILogger a circular reference would be encountered without a separate class library to store the ILogger interface.

C# - Proper Implementation Of N-layer Architecture?

Feb 28, 2011

I have been learning C# for the last year or so and trying to incorporate best practices along the way. Between StackOverflow and other web resources, I thought I was on the right track to properly separating my concerns, but now I am having some doubts and want to make sure I am going down the right path before I convert my entire website over to this new architecture.

The current website is old ASP VBscript and has a existing database that is pretty ugly (no foreign keys and such) so at least for the first version in .NET I do not want to use and have to learn any ORM tools at this time.

I have the following items that are in separate namespaces and setup so that the UI layer can only see the DTOs and Business layers, and the Data layer can only be seen from the Business layer. Here is a simple example:

[Code]....

Am I completely off base? Should I also have the same properties in my BLL and not pass back DTOs to my UI? what is wrong and what is right. Keep in mind I am not a expert yet.

I would like to implement interfaces to my architecture, but I am still learning how to do that.

Website Translation Architecture And Implementation?

Mar 18, 2011

I'm conducting a project in which a website should have multi-language support.Now, this website is supposed to serve about 500K+ visitors a day, so it must be super-efficient.

I've created a table of parameters {[ID],[Name]} AND a linkage-table {[objectID],[parameterID],[languageID],[value]}. I think it's the best way to deploy multi-language support while having the privilege to translate different parameters for each language.

As far as I know, server's memory is much faster than a physical HDD. Therefore, I'm planning to store ASP.NET Application State objects for my translation architecture.[URL]

Architecture :: Generic Comments Module (Database Design And Implementation)

Feb 10, 2010

I am in the process of redesigning our main product, a knowledge database system for clients to access clinical and specialist advice articles. There is a requirement to add "Social Networking" to this allowing users to connect and post remarks etc...

This is somewhat similar to the Facebook wall scenario - where Articles, Photos, Groups, Products, Events, ActivityFeed can all have comments. I am at a lose as to the database design I would need to implement this. All comments must allow for Moderation/Approval/Spam Reporting etc...

I originally thought a individual table for each Comments entity ex: ArticleComment, ProductComment would work as the comments themselves are not all directly related. Each table having the same exact columns. But this makes life abit awkward as then this creates a separation between something that for all purposes is the same i.e. They are all comments.

The other design idea was to have a single Comment table with an "arc" type relationship to related tables with FK references back to the source.

The other option was to have a single Comment table with an Object Type and XID but this breaks the rules of relation and does not all for referential integrity.

I am at a lose and don't know what to do. I have asked over at SQLCentral.com and all I have done is raised more questions than answers about what to do.

Design 1: This would require exact copies of this table for all the entities.

-- Photo Comments --
CREATE TABLE dbo.PhotoComment
(
CommentID int IDENTITY(1,1) NOT NULL,
PhotoID int NOT NULL,
Body ntext NOT NULL,
ReportedAsSpam bit NOT NULL CONSTRAINT [DF_PhotoComment_ReportedAsSpam] DEFAULT (0),
IsSpam bit NOT NULL CONSTRAINT [DF_PhotoComment_IsSpam] DEFAULT (0),
IsApproved bit NOT NULL CONSTRAINT [DF_PhotoComment_IsApproved] DEFAULT (1),
CreatedDate datetime NOT NULL,
CreatedBy uniqueidentifier NOT NULL,
UpdatedDate datetime NOT NULL,
UpdatedBy uniqueidentifier NOT NULL,
IsDeleted bit NOT NULL CONSTRAINT [DF_PhotoComment_IsDeleted] DEFAULT (0),
CONSTRAINT [PK_PhotoComment] PRIMARY KEY (CommentID),
CONSTRAINT [FK_PhotoComment_PhotoID] FOREIGN KEY (PhotoID) REFERENCES dbo.Photo(PhotoID),
CONSTRAINT [FK_PhotoComment_CreatedBy] FOREIGN KEY (CreatedBy) REFERENCES dbo.aspnet_Users(UserId),
CONSTRAINT [FK_PhotoComment_UpdatedBy] FOREIGN KEY (UpdatedBy) REFERENCES dbo.aspnet_Users(UserId)
)

Design 2: The "Arc" relationship

CREATE TABLE dbo.Comment
(
CommentID int IDENTITY(1,1) NOT NULL,
CommentType char(1) NOT NULL CHECK(CommentType IN ('A','I','E','G','U','P')),
Body ntext NOT NULL,
ReportedAsSpam bit NOT NULL CONSTRAINT [DF_Comment_ReportedAsSpam] DEFAULT (0),
IsSpam bit NOT NULL CONSTRAINT [DF_Comment_IsSpam] DEFAULT (0),
IsApproved bit NOT NULL CONSTRAINT [DF_Comment_IsApproved] DEFAULT (1),
CreatedDate datetime NOT NULL,
CreatedBy uniqueidentifier NOT NULL,
UpdatedDate datetime NOT NULL,
UpdatedBy uniqueidentifier NOT NULL,
IsDeleted bit NOT NULL CONSTRAINT [DF_Comment_IsDeleted] DEFAULT (0),
CONSTRAINT [PK_Comment] PRIMARY KEY (CommentID),
CONSTRAINT [FK_Comment_CreatedBy] FOREIGN KEY (CreatedBy) REFERENCES dbo.aspnet_Users(UserId),
CONSTRAINT [FK_Comment_UpdatedBy] FOREIGN KEY (UpdatedBy) REFERENCES dbo.aspnet_Users(UserId),
CONSTRAINT [UC_Comment_CommentID_CommentType] UNIQUE (CommentID, CommentType)
)

-- Article Comments --
CREATE TABLE dbo.ArticleComment
(
ArticleID int NOT NULL,
CommentID int NOT NULL,
CommentType char(1) CONSTRAINT [DF_ArticleComment_CommentType] DEFAULT 'A', CHECK (CommentType = 'A'),
CONSTRAINT [PK_ArticleComment] PRIMARY KEY CLUSTERED (ArticleID, CommentID),
CONSTRAINT [FK_ArticleComment_ArticleID] FOREIGN KEY (ArticleID) REFERENCES dbo.Article(ArticleID),
CONSTRAINT [FK_ArticleComment_CommentID] FOREIGN KEY (CommentID) REFERENCES dbo.Comment(CommentID),
CONSTRAINT [FK_ArticleComment_CommentID_CommentType] FOREIGN KEY (CommentID, CommentType) REFERENCES dbo.Comment(CommentID, CommentType)
)

Design 3: The one that breaks the rules

CREATE TABLE dbo.Comment
(
CommentID int IDENTITY(1,1) NOT NULL,
ObjectType char(1) NOT NULL, /* A = Article, P = Photo etc... */
XID int NOT NULL, /* Would be the ID of the main entity being queried. */
Body ntext NOT NULL,
ReportedAsSpam bit NOT NULL CONSTRAINT [DF_Comment_ReportedAsSpam] DEFAULT (0),
IsSpam bit NOT NULL CONSTRAINT [DF_Comment_IsSpam] DEFAULT (0),
IsApproved bit NOT NULL CONSTRAINT [DF_Comment_IsApproved] DEFAULT (1),
CreatedDate datetime NOT NULL,
CreatedBy uniqueidentifier NOT NULL,
UpdatedDate datetime NOT NULL,
UpdatedBy uniqueidentifier NOT NULL,
IsDeleted bit NOT NULL CONSTRAINT [DF_Comment_IsDeleted] DEFAULT (0),
CONSTRAINT [PK_Comment] PRIMARY KEY (CommentID),
CONSTRAINT [FK_Comment_CreatedBy] FOREIGN KEY (CreatedBy) REFERENCES dbo.aspnet_Users(UserId),
CONSTRAINT [FK_Comment_UpdatedBy] FOREIGN KEY (UpdatedBy) REFERENCES dbo.aspnet_Users(UserId),
CONSTRAINT [UC_Comment_CommentID_ObjectType_XID] UNIQUE (CommentID, ObjectType, XID)
)
-- Ex: Get all comments for article ID 23.
SELECT * FROM Comment Where ObjectType ='A' and XID = '23'

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.

So how do I decrypt what is in the database and compare with what the user typed in and then validate the user.

Architecture :: User Directory Structure?

Feb 7, 2010

I'm building a site that can possibly have millions of users (yes ambitious!). Each user can upload an image or two for his/her profile. How would you architect the directories to support this type of thing? I was thinking of having a users subfolder off the root dir where each user will have their own sub-dir that corresponds to their userId created at registration time. I could then upload their profile pics to their corresponding sub-directory under the users dir. Seems straightforward but am I missing anything? Can I have a million sub-dirs under the user dir? NTFS supports it so my guess is YES.

Architecture :: Every User Has A Parent Paradox?

Mar 29, 2010

I have a user object and each user.. has a parent! Of course one user must be the exception, can't be a rule without exceptions.

What to do with the user that has no 'parent'?

1. Create a constant/global SystemUser whose parent is NULL

2. Allow any User's parent to be NULL and hope that only 1 user ever will have a NULL parent

3. Allow a User to be their own parent implying they are the top of the food chain

Really not sure what the best strategy is here, the users will be stored in a table along with their parent user's ID. Each user has one and only one immediate parent.

Architecture :: Limit User Input Options?

Jan 19, 2011

I'm building a web app (VS2010, C#, .NET 4.0) and am aiming to make heavy use of objects. One particular object will be a 'user' object. One of the properties I am exposing for the object is the users Status (e.g. Pending, Active, Suspended, Expired). In the front end this status will be editable and I don't want users of the app to enter invalid statuses (Pendong, New, etc.). I could hard code the valid statuses in the front end making use of a radiobutton list or dropdownlist, but that isn't logically where the valid values should be defined, I would have thought that the objects class would be a better place.Now this leave me with two problems:

Which is the best place to define the valid values? If I add them to the class, how do I read and present them in the front end?I'm hoping that you guys can put me straight here. Are any of my ideas architectually correct, or if not then what would be better.

C# - Basic "add User / Edit User" Forms Authentication Functionality In MVC

Jan 4, 2011

I want to use forms authentication on my ASP.NET MVC site. All I need is a place for users to login, a page to add a user, and a page to edit a user. I'm using all the default ASP.NET forms authentication tables for SQL Server (aspnet_Profile, aspnet_Roles, aspnet_Users, etc.). The only difference is that I've added an Employees table to my database, which contains a FK to aspnet_Users to create a one-to-one relationship. The Employees table contains columns for FirstName, LastName, StartDate, etc. It's a way for me to keep additional information for the users.

I'm having trouble finding any sort of tutorial that would help me build a basic page in MVC, everything I find is for WebForms. For my page to add a user, I'd like there to be fields for the Employees table. I don't know if I can modify the CreateUserWizard to add those fields, or if I'd be better off just creating my own custom page.

Architecture :: How To Save The Current Location Of Each Logged-in User

Jan 26, 2010

Let me tell you what I need to implement on my company .NET application and I will be more than glad to hear your advise how to do it:

For every user loged-in to the company website, We want to know on which page he is right now. It means, If user X is now on page "1.html", I need to save this information somewhere. If user X after 30-60 seconds going to page "2.html" I want to update it fast where he is now surfing. It means I want to be able to tell at REAL TIME, on each page, Which users are right now observing the page. This is the problem, now I'm looking for the right solution.

If some day my company website will have 400,000 user log-in at the same time, I am going to save to every one of them where he is surfing right now. Maybe I exaggerated, but we do have 45,000 users at the same time on the company web site and the number is growing. I think big so the solution for this problem will be good for a lot of users.

So, my data object for every user should keep this information somewhere:

1. User code (User Number).
2. Which page user is now observing (Page Number).

This object is going to update every 30-60 seconds by using AJAX, so it should be updated fast. It is a lot of reading/writing data. If a user want to see which other users are now on the same page as he his, he will be able to see it, just by going through the whole array of objects.

I don't need this information to be saved in DB, because it doesn't mean anything. It is temporary and changing A LOT. So, I think the right place to do it is using RAM at the the company server, using the Caching Data option. What do you think? Am I wrong?

If I am going to have a data table with lots of records and every record is going to be update every 30-60 seconds. Where should I save all this table data? I am using SQL Server 2008 to save important data as needed, but this data is not important to save, just need to use it for my purpose. Where should I save this data? I think saving it in DB is a bad idea, because of the dynamic update of records every few seconds. I am thinking about 100,000 users who update this table every few seconds. It probably going to kill my DB, so DB is not an option.

What is the right way to implement this kind of thing?

You may think of it like every page is "a chat room" and I want to know who enter now the room (the page), it doesn't have to be completely accurate in time, but approximately.
