Intro to Data - 04-07 - Summary

In this module, we learned about data types and how we represent and store data in a computer. First, we learned about data types, binary representations of data used by computer systems. Next, we learned about scalar data types, representations of data that store a single value. Then, we saw examples of common scalar data types, including: characters, integers, dates, and times. Next, we learned about composite data types, representations that store data as a group of related values.

00:29 - Finally, we saw examples of common composite data types, including: vectors, tables, graphs, and images. In the next module, we’ll learn about tabular data and how we extract information from tables of data using queries. .
