Hi all,

I'm going developed a function that the user will get notification message if some event happened. The event happened due with machine breakdown notified by production supervisor. The Production supervison will insert message to database.

My question is,

1) it is i need to create a timer to select data from database every predefined interval ?
2) It is when supervisor insert data to database will send message to server ( Windows Server 2003 ) to ask the server response to selected user ?
If the second method is better, how can I do with this ?
3) Any others better suggest mind to give me a hand or guide ?

Thanks you.
