Architecture :: Webapplication Design / How To Large Structure
Jul 11, 2010
how 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

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.

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

I am using asp.net 3.5 and I am trying to create a project structure (asp.net web solution with UI/Business/Data access) which would be like a base and ready for any new projects in my team and all could use this standard structure only as a base(outer boundary) and they can expand the structure. Also adding on to it I wanted to include certain features like adding libraries of reusable code/functions, so that every team member could use functions from my library within this base structure. To summarize the above, I need to create standard .net project structure/framework/architecture with resusable code library included in it. How can I do this..

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.

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.

I am not new to ASP.Net application development but I haven't used some of the new frameworks or features that are used in applications these days.
For cross-cutting concerns, things like: Logging, Caching and DAAB are used in projects these days to implement proven and efficient source code from either Microsoft or other third party vendors such as Log4Net for logging purposes.

I am currently working on a page that has 13 gridviews in it. Each one is in a control and a separate updatepanel. The time from link click to page load is 20 seconds though and I am looking for ways to load the controls asynchronously so that the page can load and then the data can come after. I have tried a few different methods so far but have been unsucessful so far. I thought about using the Ajax incremental page display pattern but I did not think this would work because it only returns html. I need to load the gridviews in and they need to support pagination and sorting.

I have a scenario which I am looking at where large files which are about 30-40 MB are being FTPed to a server. I am looking at creating a .net screen with the FTP control to upload the file to a Unix server. I need to know how much of a performance hit it is to work with such large files, is it a feasible option in this scenario? I might have to create a .net component for the same and call from ASP application. Is it doable?

I am building a small mass email application for my department. Which basically emails out a notice to a large list of email addresses. Because the company email server limits the amount of email addresses that can be contained in a single email I have to break the list apart into smaller 100 email groups.
I've create the query to pull all email addresses needed, stuffed them into a collection but I am not sure how to grab 100 emails at a time and send it off to another sub to perform the email send before grabbing the next 100.
This is what I have so far.

I have a project that will be assigned to me soon whereby I need to develop a survey which needs to support 40,000 users approximately. Now we are thinking of doing a staged approach so not all users are on the server at any one point of time. Probably splitting it so we can serve at least a few thousand of users...
I dont have much experience of how I can ensure to serve those levels of users on a server and how to manage this so I am after some advice?
From my understanding I need to do some stress testing on a server and obviously I need some figures i.e. average size of request, average size of response and content of response.
- Do I have to build the database and add records in to see what size is a typical survey row?
- Do I have to build the survey in .NET i.e. by adding controls etc and seeing what size is the page?
- The survey shouldnt be too instensive processing wise, it will be adding information into a backend sql database...

I have a table growth 100000row per day, I'm facing many problems to export data from this table using ASP.net page.
I don't know how to apply this scenario:
Senerio 1:
1- run Asynchronous function to export data from SQL for specified period to CSV file (without locking the table)
2- Refresh page every 5 sec in order to track the status of extracting data
3- compress the file
4- Stop refreshing and showing the download link in order to download the compressed file
or
Senerio 2:
1- run Asynchronous function to export data from SQL for specified period to CSV file (without locking the table)
3- compress the file
4- send the compressed file by Email

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.

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.

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?

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?
