Amazon and Dimensional Modeling


Hey guys,

I am back with my new blog. This blog mainly contains a brief description about Amazon and its business. It then talks about what could be some metrics that will be useful for the CEO to track the progress of the business and how dimensional models can be used for this purpose.

Introduction
Amazon.com, Inc. or simply Amazon is an e-commerce and cloud computing company in the United States headquartered at Seattle, Washington. Amazon is the largest online retailer in the United States. Found in 1994 by Jeff Bezos, it started out as an online bookstore and later on branched out into DVDs, CDs, software, apparel, furniture, etc. It has also grown its business beyond USA and maintains separate retail websites in many countries in Europe and Asia.

Metrics
Amazon’s business has been growing and to maintain its top spot in the online retail world, it will help CEO Jeff Bezos to have some metrics to analyze the performance of the company. Following are some of the metrics:
1.       Total quantity of items sold in a given time period: This metric will give an idea about the sales side of the business. It does not tell anything about the revenue earned from the items and hence, the items could be anything like cheap, expensive, large or small items.
2.       Revenue earned from selling these items: The revenue metric can be used to gauge the economic factor of the business.
3.       Profit: This metric can give us an idea about the actual money Amazon is making. By analyzing this metric, we can determine how much to spend based on the amount of returns we are getting.
4.       Number of items returned: This is an important metric for Amazon’s business model since it will help determine the percentage of faulty items in the warehouse. If this number is more, it means the suppliers are sending defective products and they need to be communicated to rectify the problem.
5.       Revenue earned per customer: Customers are important for Amazon and to know what revenue each individual customer is generating can be of great importance. By finding patterns among the high revenue generating customers, Amazon can make special offers for them.
6.       Revenue earned per item category: The category information can be useful to judge what categories are selling more and what are selling less. This way we can focus our attention to a particular category during Sale seasons.
7.       Items sold together: We can also analyze to see which items are often purchased together and add them in suggested list of items or create special offers on these items.

Dimensional Model
The metrics can be best tracked with the help of a dimensional model. With the help of a well-defined grain, these metrics can be accurately monitored. Dimensional models can help to bring together the required data from different sources and generate a single and consistent view for the user. Dimensional modeling can reveal certain inconsistencies and also help in fixing them. Whenever there are ad hoc queries, a dimensional model can help execute them to solve business problems faster and better. Dimensional models can also help increase the flexibility and scalability.
For Amazon’s business, Periodic and Transaction snapshot both can be equally appropriate. I would, however, go for the Periodic snapshot as it will give us an idea about all the metrics discussed above from time to time on a daily, weekly, monthly or yearly basis. A transaction snapshot can give us information about each transaction but we can analyze those with our metrics. From the point of view of future growth, the Periodic snapshot suits best the needs of the organization.

A sample dimensional model can be as follows:





In conclusion, dimensional modeling can be of great help to Amazon’s CEO Jeff Bezos to help determine important factors for company’s growth and make key business decisions.
