Hi, thank you for your article. I found it very interesting. In addition to the skills proposed in your article, data enrichment could be added.

Data Enrichment is often understimated, but it could add value to a dataset. For example, adding geographical coordinates, such as latitude and longitude, may lead to the discovery of new information in a dataset.

Data Enrichment may be performed by searching for new data or by exploiting some services, such as those provided by APIs.
