Actually I want to reuse/upgrade the footmart modeling for my website. I am designing a geo-location based general supermarket promotion web site, which is an electronics product catalog and online ordering system. However I found the data modeling is quite huge.

I design chain store and product list, which is many to many relationship, it seems the data redundancy is huge. For example, if I consider Walmat, Carrefour as stores, which have 200 items to sell. I have only 400 items to list. If I consider Walmat Shanghai as one independent store from Walmat Beijing, then we got double. So geolocation-sensed design will increase the data very quickly. The reason I design geo-based database, because supermarket is always regional orientated, in most of time, they don’t share the same product list.

If I consider the system to serve more than 100 chain store, which have 10~100 stores in China, each one has listed 1000 product items. The data is huge, huge data redundancy and tough work for data uploading.

Any good ideas ?
