Hi, my name is Nigel. I graduated from Nanjing University of Aeronautics and Astronautics and began my career designing rocket components for China’s aerospace program. So unlike the so-called “rocket scientists” on Wall Street, I am the real deal. For the past 20 years, I have helped foreign businesses achieve a smooth landing in China, navigating everything from market strategy and regulatory compliance to local partnerships and execution. I speak the languages of engineering, mathematics, and cross-border business. Let us have a cup of tea at a peaceful Buddhist temple and talk business.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
