Hi,

I have read many articles on three tier architecture and also tried some code on that but the way I tried was not correct.
Actually I was writing code for insert, update, search etc.

I know that in 3 tier we open and close the connection in data access layer which I was not able to do properly.
I want a proper code for insert, update etc using 3 tier architecture
which I can easily understand and implement.

I''m new to 3 tier architecture

Please help.
