Data Governance - Data Management

Recently I had the opportunity to present at Datavader, a Data Science Learning Portal run by Shruthi Pandey. The topic of presentation was on Data Governance, it was a fun and interactive session with good participation given the importance of the topic. We had a Q&A Session at the end of the presentation. I am attaching some of the content from the deck of my Presentation, it is a simple compilation of articles , diagrams from different blogs, websites to convey the importance of Data Governance.

The 4 C’s

Completeness — How much of the data that’s expected is there? Are the ‘important’ columns filled out? 

Consistency — Are data values the same across data sets?
Conformity — Does the data comply with specified formats?
Curiosity — Are stakeholders knowledgeable and/or engaged in the data management lifecycle?

The 4 V’s

Volume — How much information is present?
Velocity — What’s the frequency of incoming data? How often is the data processed and propagated? 

Variety — What types of data exist? Is the data structured, unstructured or semi-structured? Veracity — Is the data trustworthy? What are the inherent discrepancies?
