Question

I am currently developing an asp.net mvc 4 application with .net 4.0.

A critical requirement is that I must allow for updates to be made to system even if Database is down (it could be down in night time, but some users still need to login and use the system).

I have never experienced this problem before and have no idea of how to do it? Or even is it possible?

Please give me some instructions or some tutorial links. I am really appreciated.

(I also did some researches, and found some tutorials about asynchronous controller in asp.net mvc. But I wonder if it can satisfy my requirement?)

You can use MSMQ to queue your requests to server and process them one by one.You need to make sure that this server never gets down.
