What Supply chain management is
A subset of value chain management, it is an old system that's been updated with new technology. It specifically refers to the relationship between a supplier and a retailer. For example, a major retailer can monitor surplus on its shelves right down to an individual product, and this enables the retail store to keep its supplier aware of how its product is selling. In return, the retailer may demand favorable promotions from the supplier.
The meaning of Affiliate marketing
A revenue sharing arrangement between online advertisers or e-commerce merchants and online publishers or Web site owners, whereby payment is based on performance measures, such as the number of sales, clicks, or registrations that the affiliate refers. In other words, two companies agree to link to one another; if someone clicks from site A to buy something at site B, site A gets a commission on the sale. Affiliate software provides the tracking and reporting of commission-based activities (the sales, clicks, or registrations). Amazon.com pioneered affiliate marketing by getting as many other Web sites as possible to join its affiliate network and sell its products, thereby greatly extending its marketing reach.
