Realtime data on a webpage

[pisoftwar]

Gentlemen,

I need some guidence on a task I have been given.

Is it possible to have a web page display data collected in a database?

I have a table collecting real time data from units in the field and would like to display the data in a graph without having to refresh the entire page (something like the task managers graph on the preformance tab).

 

I was thinking I would have to use an activex controls but one of the requirements is not to install anything on the clients computer because security will interfere with that method.

 

Is there any other methods that I can use?

 

Does anyone know of some java sites that have related information?

I've not used it, so don't know how well it will work, but you might want to look at Atlas. It is an extension for ASP.NET 2.0 that allows you to use AJAX techniques to update portions of a web page, instead of the entire page.

tfowler said all you needed to know :) Atlas is great for that, but you have another AJAX open source library (SARISSA) ready to use in http://sarissa.sourceforge.net/doc/

 

Besides this you can always use when possible CSSs it improves page reloads because its very light and runs at client side.
