Amazon.Com

Everything you see on Amazon.com is going to be driven from a database. Every purchase that is made is stored in a database. Amazon uses this data to help find products you might like, based on previous searches. Every time you view a product the information is logged so that Amazon can recommend other products. (Rainer & Turban, 2009). Amazon.com also allows users to submit reviews for each product using a rating scale. Reviewers must rate the product from one to five. As Amazon has grown with increasing business and popularity, the amount of time it took IT staff workers to update the web page increase. By using Excelon Corp’s Object Store Database as a management system, Amazon has cut their website update time from eight hours to two minutes. (The Amazon Relational Database Service. 2009). Differential pricing is an issue Amazon.com has had to deal with. In September 2000, Amazon.com was found for price discrimination. Amazon offered to sell a DVD for one price, but after the buyer deleted cookies that recognized him as a regular Amazon customer, he was offered a lower price. Amazon vowed to never test prices based on customer demographics.
