1 Consider the following online shopping portal-
A customer visits online shopping portal. A customer may buy item or just visit the page and logout. The customer can select a segment, than a category and brand to get different products in the desired band.
The customer can select product for purchasing. The process can be repeated for more items. Once the customer finishes selecting the product/s, the cart can be viewed.
