What is the best way to retrieve data from SQL Server 2005 for a performance hungry web site? I was thinking of using sqlconnection+datareader+stored procedures but I'm not keen on the idea of writing sqlconnection every time. I like using typed datasets but I really need the maximum performance for the site and I don't know about it's performance. What do you think? Should I go for my own DAL? Or are there good DAL components that I'm not aware of that I could use? Any opinion is appreciated.

Just declare one connection string at the top of the page
Then use stored procedures

Your best bet is to use a sqlconnection and datareader. You biggest bottleneck will often be your sql queries. So if you have data that doesn't change very often use System.Web.Caching...
Do not use typed datasets, they are a performance killer. If you want you can use class objects to represent your data and use generic lists instead of typed datasets.
Also, you can call one stored procedure to get all of your data. Just return multiple result sets and use reader.next
I didn't get any requirements for the signature

Can you explain a bit more:
Are the values to be entered through a form
if so just create a loop and loop the insert for each new entry

i have this below problem while executing a transaction.
I am trying to insert into two different tables with differnt values on the same btn_click event.It is taking the second table value not the first table
I am posting my code here-----
Dim mycommand As New SqlCommand
Dim myTrans As SqlTransaction
myTrans = myconnection.BeginTransaction()
mycommand.Connection = myconnection
mycommand.Transaction = myTrans
Try
mycommand.CommandText = "insert into tbl_student(st_cd)values(1)"
mycommand.CommandText = "insert into mst_year([Year],Start_Date,End_Date,year1)values('2002-2003','4/1/2002','4/12/2002','2005')"
mycommand.ExecuteNonQuery()
myTrans.Commit()
Catch ex As Exception
myTrans.Rollback()
Response.Write(ex.Message)
Finally
myconnection.Close()
End Try
In the above code values are insertig in mst_year table only,not in tbl_student.
I want to save in both tables.how it can be done?

Hi All,
i have a requirement to change the language of my webpage at runtime by hitting on language buttons. i have gone through this article.
http://www.codeproject.com/KB/aspnet/DynamicWebMultiLanguages.aspx
i have one doubt in this. In this article they used resource files for each lang. under resource files they give the values for the strings which they have used in webpage.
But i have dynamic data showing i gridview which is retriving from database. for this how can i change the data to another language. hundreds of records will be in there in grid and data will change frequently.

Hi! I'm bit confused about 3-tier architecture and need some advice in the right direction.
1.If I'm having a single project in which I have separate classes for Business layer and separte class for Data access layer. Is it an example of 3-tier architecture???
2. If I'm having 3 separate projects, one only involved with displaying the data and one is a web service/window app invoked through remoting and the third application working as data tier. Is it a proper example of a 3 tier architecture??
Please correct my understanding or provide a link to a good article or ebook.
Thanks in advance.
