Chapter 23

Case Study: A Programmatic Example

WHAT’S IN THIS CHAPTER?

• Understanding the business situation
• Architecting a data quality solution
• Setting up the case study
• Implementing the ETL

Usually, a book like this has to cover so much material that there is not enough space to really dig into some of the typical issues that can arise when you put the book down and begin your first solution. You end up returning to the book to flip through all the one-off examples, but they just don’t seem to provide the insight you need or to apply to your current project or deadline. Looking at a case study enables you to get specific — that is, to get hands-on experience with a real-world business issue and run with it. By working through the example provided in this chapter, you will gain the fundamental knowledge and skills you need to tackle your own project.
