IQ International Webinars:


Data Quality and the Second Law of Thermodynamics


Thermodynamics is the study of systems of particles and their behavior.  Beyond studying temperature and understanding heat and cold, It provides us mechanisms to understand the behavior of particles as they move between what physicists call ‘accessible states’.  If we begin to look at a single data element as a particle and its various values as accessible states, we can draw many useful parallels between a system of particles and a data set. 

As a single example, we look at the entropy or ‘randomness’ of a system and we recall the second law of thermodynamics which states that the entropy of any system will always increase over time unless energy is inserted into the system.  With this consideration, it is no wonder that data quality continues to worsen over time. 

We will explore this and other analogies and attempt to leverage what we have learned about thermodynamics over centuries of study to better understand the complex behavior of our systems of data today.

About the Author

Gian Di Loreto

Gian Di Loreto is one of the USA's leading authorities on human resource data quality and is currently Senior Consultant at Profisee Group.

Gian holds a Ph.D. in particle physics from Michigan State University. He began his career as an experimental physicist at Chicago's world-renowned Fermi National Accelerator Laboratory (Fermilab), where he spent several years performing statistical analyses and identifying errors in massive databases generated by proton/anti-proton collisions. After his tenure at Fermilab, he leveraged the analytical skills he developed in a scientific context as a software developer for a firm that reconciled and corrected data generated by General Motors' pension funds.

He has worked at Loreto Services & Technologies, a consulting and IT outsourcing firm whose mission is to help companies understand what is in their databases, identify errors and discrepancies, integrate disparate databases and, in the process, eliminate historical and ongoing mission critical data errors using proven, scientific and statistical techniques.
