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.
I'm looking for a simple way of developing "System Notification" in an ASP.NET website, which will consist of two parts: Part 1 - The administrator with go to a special page and enter 3 elements for the notification:
Notification Text (e.g. "System will be down for maintenance next Sunday 11/26/2010 from 1:00 AM to 1:30 AM Pacific Time) Starting date/time when the notification should be displayed (e.g. 11/23/2010 6:00 AM) Ending date/time when the notification should be displayed (e.g. 11/26/2010 1:30 AM) Part 2 - Once the user logs into the website within the above timeframe, the system notification message will appear on the home page. What would be a good architectural location for this?
- A table?
- An html page?
- Part of web.config file?
- A new notification.config file?
- Where else?
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.
I am implementing 3-tier architecture. I just wanted to know the role of business layer in 3-tier architecture.

View 3 RepliesWe 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

I am creating an ASP.NET MVC application and want to display an icon in the view based on a value of a property in the model. I guess I want to have the logic deciding which image to show in the business layer (which is in a separate class library project) but the actual images files in the web application's "Content" folder. Should I set the url of the image in the business layer? I don't want the business layer to know that is serves a web application, it can be a Windows Form or WPF application as well. If I set the url with System.Web.HttpContext.Current.Server.MapPath it feels like I am getting an unwanted dependency on System.Web, right? What are the options here?
View 1 RepliesI am working on implementing a web application in ASP.Net by following the MVC design pattern (Not ASP.Net MVC). As part of the design, we have entity objects that has only properties as per the corresponding table structure and the idea is using these entity objects in the view layer and the same entity objects are passed to Persistence Layer for saving the data to the database. Business Objects in the business layer are responsible for interacting with the database.
As view creates the entity objects and passes to next layer, what would be the best practice to pass the entity objects to the business layer? Should the business objects accept data objects as parameters and interact with the persistence layer? Is there any other best practice to pass the required objects from the view layer to the next layer? As business objects also need to access the properties of the entity objects passed from the view layer, do we need any "translation" from entity objects to business objects?
the best practices to pass entity objects from view layer to the next layer and also how the entity objects created by the persistence layer can be used by business objects?
I do not know how to create a business object for inserting data into the database.
View 2 RepliesI have the following scenario,There is a master business object containing 40 fields2 separate child business objectsIf I update a child record, I have to update master's 'Last modify by' status along with 3 or more fields in masterFor this purpose, I don't want to initialize a separate Master class object (as most of the fields are unused/wasted)The 'last modify by' also gets updated if the records in master get updated themselvesCurrently I have separate business objects for master table, Child 1, Child 2 etc.
How do I control this in my business object design ? Do I break up my master object ? Say I extract last 'modify by ' into a new class, through inheritance or some other way ?Is there a way that whenever child gets updated I use a 'small' class to update Master status only and whenever the master itself gets updated I do the same.Problem is that I am having redundancy in my small class (Master class also contains 'Last Modify By ',
I am going to develop new application in asp.net .But I want to create business/data access layer in such a way that I can reuse it in any other interface (Smart Phones,php etc).how can I achieve this ?I need to create project architect according to that.
View 2 RepliesI've inherited an asp.net web solution, which has business logic and data calls as seperate assemblies. In the business layer there are a small number of calls to get/set HttpContext session values. I've looked around for an example that will allow me to abstract this away from the business logic as I'd like to be able to reuse these assemblies in non-web projects, could anyone please give me an example of the best way to do this. I was thinking of some sort of session factory that will obtain values from some sort of persistant store depending on the usage scenario but I'm new to architecture really and would appreciate a pointer or two.

I'm currently developing a web application whose primary user function is uploading and downloading of files. The files will be stored on the hard disk (no cloud storage yet).
Taking into consideration the possibilities of gigabytes of data and a large number of files, do I need to organize files into sub folders to account for the fetching of a file or is the file system's indexing already very efficient and I can ignore this potential bottle neck?
Update:
On a side note, I plan to store file names and any additional information in a SQL database and only query the disk when a user actually wants to download the file. This is how I plan on retrieving files:
FileStream stream = File.Open("C:file.txt");
byte[] fileContent = new byte[stream.Length];
stream.Read(fileContent, 0, fileContent.Length;
Any file information will be retrieved from the database. The hard disk will only be used for saving and fetching files.
Update 2:
Files will be saved as GUID + EXTENSION on the hard disk while the actual file name is stored in the database.
List me guidelines which we have to follow while developing an asp.net application with improved performance:
-Using Pooling properly, Stored procedures, when to use AJAX update panel etc etc

View 9 RepliesI am developing asp.net application that will be used primarily on iPhones. On one of the forms I have a textbox where users enter a date. I am using a javascript calendar on that same box so its easier for users to enter dates. But when a user clicks on this field in iPhone, the phone brings up its own menu (with keyboard) on top of my javascript calendar. That makes it look very ugly as a user now has to click on Done to close that keyboard and onyl then start using the calendar. Is there a way to prevent iPhone from displaying this keyword?
View 2 RepliesI am developing a web application which will deal with online examination. The requirement is:
There can be n-number of sections in an exam and admin users should be able to create questions/answers and add to an exam. The questions should be displayed for a certain amount of time in the browser with meclock and it should move to next question automatically. User should not be allowed to open any other instance of the browser or login from another IP if the exam is in progress.
I am seeking community vote of how would someone design the application to meet all these criterias? What patterns should be used? What components to reduce the development time etc..My technology stack is C#, ASP.NET MVC or ASP.NET with SQL Server.
I currently have a ASP.NET web application that was designed for desktops/laptops. Now we need a mobile version of this application. I have never developed mobile application before and am looking for any good tips before i start. Things that i have been thinking about like how do you know when load the mobile version or the normal version.
