Course Conclusion

The course is part of this learning path

Start course

This course explores data sources and formatting, and how to present data in a way that provides meaningful information. You'll look at data access patterns, and how different interfaces allow you to access the underlying information. This course also provides a practical, real-world example of how all this theory plays out in a business scenario. By the end of this course, you will have a good foundational understanding of how to wrangle and visualize data.

Learning Objectives

  • Understand the difference between data and information
  • Learn how to make data useful in order to gain insights from it
  • Learn how to store data correctly
  • Understand how these techniques can be applied in the business world

Intended Audience

This course is ideal for anyone who is required to interpret or understand data for reporting purposes or for use in machine learning initiatives.


To get the most out of this course, you should be familiar with relational databases such as SQL or NoSQL and some common data formats such as CSV and JSON.



So to wrap things up, data is turned into information through processing. This processing can take the form of formatting it to improve human readability, aggregation, and enrichment to combine it with other sources of truth, organizing it so that it's more readable and assessable, and providing analysis to detect hidden trends. Furthermore, visualization is key to making the information understandable. Insights and actual value is often driven through processing the data and combining it with a well-made visualization.

So hopefully this has given you a better understanding of how to prepare data, so as readable, usable, and useful when visualizing it. As always leave a comment or feedback if you have any thoughts, and I look forward to seeing you for the rest of the data engineering learning path. Thank you.
