Topic:

Data Quality and the Second Law of Thermodynamics

Abstract:

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.
