I am wondering, is it possible to have data mining on a single table with a large amount of data?
The given table is about sales and contains all the needed info (SellerType, ShopLocation, ItemCategory, ItemCondition, Sold, Price, ShippingCost).

I tried to create a data cube but I can only get one dimension.

What I want to exam is the affect shipping cost has on sales based on category, or the price based on condition and category, etc.

Any thoughts?

Thank you in advance.

I found the solution and I'm posting it in case someone else have the same problem.
The answer is to create relational tables as following, instead of having one table with all the data in it.

Table Sales ((SalesID, SellerTypeID, ShopLocationID, ItemCategoryID,ItemConditionID, Sold, Price, ShippingCost)
Table SellerType (SellerTypeID,SellerTypeDescription)
Table ShopLocation (ShopLocationID,ShopLocationDescription)
Table ItemCondition (ItemConditionID, ItemConditionDescription)
Table ItemCategory (ItemCategoryID, ItemCategoryDescription)
