Data integration in the era of big data and outdated ETL technology

A large business company may need to categorize products and customers from several levels, and expand marketing activities in segments. For the company’s smaller subsidiaries, this can be achieved through a simple product and customer classification hierarchy. In this example, a larger organization might classify a can of Coke as part of a carbonated drink, a beverage, and food and beverage sales. However, smaller subsidiaries may include the same Coke in food and beverage sales without an intermediate classification. This is why classification consistency—or at least an understanding of differences—is needed to get a global view of the company’s overall sales.
