Data Feeds - Load and Comparision

[Black Magic]

Hi Rosaline and Everyone!

I am a Newbie to this business and I had a few questions concerning the use of Data Feeds.

1. I have been doing research on the use of Data Feeds. I can't seem for find a lot of post concerning the subject. If I have missed something, could someone please direct me to a Subject Matter Expert or the proper post?

2. I would like to specialize in the advertisement of specific items from across several merchants. Is it possible to merge different merchant data feeds using Web Merge? Is there a standard data schema for Merchant data feeds? I am using ASP as my site code base.

3. Are data feeds real-time or batched (non-real-time)?

4. Is there a "plug and play" script for the product comparison feature for displayed products? If so, can this feature be used with data from different merchants?
