The most universal data structure – a table

Regardless of the complexity and high Vs of your data, and even regardless of you wanting to do data visualization or machine learning, successful data preprocessing always leads to one table. At the end of successful data preprocessing, we want to create a table that is ready to be mined, analyzed, or visualized. We call this table a dataset. The following figure shows you a table with its structural elements:

Figure 3.4 – Table data structure

As shown in the figure, for data analytics and machine learning, we use specific keywords to talk about the structure of a table: data objects and data attributes.

Data objects

I'm sure you have seen and successfully made sense of so many tables and created so many of them as well. I bet many of you would have never paid attention to the conceptual foundations of the table that allows you to create them and make sense of them. The conceptual foundation...
