Why should you care what I say?

I have worked with data for most of my adult life. I have worked with data from the Visible Human Project, the Human Genome Project, a major European Soil Database, Medical Imaging Data, and loads and loads of Data from Clinical Studies Research.

I now help other scientists and business analysts just like you get the story of their data quickly and easily.

The simple rules for the data cleaning processes that you have devised enable someone new to data cleaning to easily learn how to do data cleaning and to become fast, and effective at doing it. I used the book to help a SQL programmer, who had never been faced with data cleaning, to get to grips with the task. I had her copy about 100 rows at random from several of the database tables into Excel sheets and then apply your approach - from Tip #3 onwards. With very little help she gained a good understanding of her data and how to clean it. Now she is writing SQL code to clean all the data in a very large database. I learned the benefits of going back to the basics. Using your book the programmer learned much more about understanding data and how to clean it than she would have done than if I had tried to teach the same skills through writing SQL code.
