Hi, I'm new to this thread. I need someone to help me out in deciding the following:-

I'm creating a asp.net web application that only displays a lot of data from Oracle 10g database tables. These data or the informations shown on the webpage will be changing very frequently and I need to refresh only those data that have changed in the database and almost at the same time. I'm planning to use json with asp.net ajax page methods for UI and Database Notification. But, somewhere I read that using Database Notification is not recommended for frequently changing data.

Under the above scenario please let me know the following:-

1. What logic/architecture should I follow?

2. Is there any benefites of using WebService or WCF over ASP.NET AJAX PageMethod?

Please suggest.

Thanks in advance.
