"Few of us today would consider developing code without the support of a version-control system.  And yet our data - which is the lifeblood of our business - tends to exist only in a “present tense”, with no versioning at all.  
 
What would it mean to version data?  What would versioned data look like, and how would it differ from versioned code?  Most importantly: what would be the business benefits of routinely version-controlled data?  In this talk, Jules presents some of the key learnings from a recent project he led which was set up to answer these questions."
