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,
Next, we learned about composite data types,
representations that store data as a group
of related values.
Finally, we saw examples of common composite
data types, including: vectors, tables, graphs,
In the next module, we’ll learn about tabular data and how we extract information from tables of data using queries.
