Ted Codd was not a Developer, or a Universal Theory for Big Data

Grand Ballroom - Salon A/B/C/D

For the last few decades, the relational database has dominated the industry when it comes to building data-centric applications. The mathematical foundations of SQL and the relational data model were key to ignite this multi-billion dollar business since general abstract knowledge about relational databases is applicable across any concrete implementation.

Recently there has been a surge in the interest for non-relational databases ("NoSQL") and so-called "Big Data". However, the landscape of Big Data remains fragmented with many (seemingly) different implementations and approaches, unable to interoperate and seemingly distinct from each other, preventing the non-relational approach to data to reach it full potential.

To get rid of this Tower of Babel we need to seek a mathematical basis for Big Data that emphasizes the correspondences between the various solutions, as opposed to strutting about the differences.

In this talk I will break down the relational data model and build a universal theory for Big Data. In the process we'll discover how Monads and Category Theory can help us along the way, how the mathematical concept of Duality helps us make sense of the 3Vs of Big Data (Volume, Velocity, Variety), and to top it off: how any developer could have come up with all of this by remembering the design principle of separating interface and implementation.

We can only imagine how the world would look right now if 45 years ago Ted Codd would have have gone through the same design process.

Unfortunately, he was not a developer.
