What is the LOGIC to make price comparison site like [http://www.shopping](http://www.shopping/) .com  
How can we upload single CSV for different category products with different properties and attributes, please help me if ANYBODY can.

EX: for \*\*computer monitors \*\*have properties like  
Technical Features (Form Factor,Digital Video,esolutions supported,…) ,  
Dimensions (Width ,Depth ,Height, Weight),…

But for **camcoders** have properties like  
Memory Photography (Memory Card Type ,Digital Still Shot Mode,MPEG Movie Mode,…) ,  
Interfaces (Output Interfaces,Input Interfaces,Microphone Type),  
Power Supply (Battery Type,Battery Life),…

How can we insert these different types of products.

I want to know how is the [shopping.com](http://shopping.com) works.

waiting for replay…thanks .
