What are open data sources?

Imagine that you’re doing some data researches to support and ensure that the content produced in your business is coherent with the brand. This type of data can be located in external sources around the world. It’s what we call open data: large datasets that are available to everyone connected to the internet.

Moreover, open data sources are important because they are a powerful material freely shared by government agencies and other trusted institutions, for instance. In terms of usability, you can optimize your data culture and find out new opportunities for innovation, produce great data visualization, and even improve your data literacy.
