Example

You are an investment banker who needs to calculate the popularity and risk of stocks and then match stocks to each customer based on the preferences of the customer. Your CIO wants to automate the process of calculating the popularity and risk of each stock, match stocks to each customer, and then send an email with a list of stock recommendations for all customers.
You consider the following requirements for your project:
  • The volume of data generated by each stock is greater than 10 terabytes.
  • You need to analyze the changes to the stock in microseconds.
  • The stock is included in Twitter feeds and company stock trade websites, so you need to analyze these social media sources.
Based on your requirements, you work with the IT department to create mappings to determine the popularity of a stock. One mapping tracks the number of times the stock is included in Twitter feeds, and another mapping tracks the number of times customers inquire about the stock on the company stock trade website.
