What is a data model?
The reason the answer isn't so simple is because I am usually consulting downstream from the data modeling. Not an enviable position but in most cases, the importance of agreeing on which metrics to include, what data to collect, and a cohesive set of data definitions is overlooked--until it is too late. And then--my phone rings.
...working data scientists make their daily bread and butter through data collection and data cleaning; building dashboards and reports; data visualization; statistical inference; communicating results to key stakeholders; and convincing decision makers of their results.--What Data Scientists Really Do, According to 35 Data Scientists--Hugo Bowen-Anderson
One result of this rapid change is that the vast majority of my guests tell us that the key skills for data scientists are not the abilities to build and use deep-learning infrastructures. Instead they are the abilities to learn on the fly and to communicate well in order to answer business questions, explaining complex results to nontechnical stakeholders. Aspiring data scientists, then, should focus less on techniques than on questions. New techniques come and go, but critical thinking and quantitative, domain-specific skills will remain in demand.--What Data Scientists Really Do, According to 35 Data Scientists--Hugo Bowen-Anderson
Perhaps there are mythical hordes of talent that know 8 different programming languages, well-versed in statistical and predictive modeling, machine learning, clustering and classification, Python, Scala, and Java, SQL, Hive, Spark, etc. and are subject matter experts, can data source, and communicate all of the processes and deliverables clearly to all stakeholders.
Good luck finding them--I don't have time for all of that. Too much work to do...

Or we are just smacking ourselves in the head with fish. Listen to the podcast below from The Economist Radio. The Secret History of the Future: The Body Electric.
We’ve used electricity to treat our brains for thousands of years, from placing electric fish on our heads to cure migraines to using electroconvulsive therapy to alleviate depression. But over time, our focus has shifted from restoring health to augmenting our abilities.
