Summary

In this chapter, we continued to learn about SQL queries as a way to filter datasets and generate focused responses to questions. The goal for writing SQL syntax is to feel conversational—building on the ability to ask specific questions. Understanding location and being able to dig a little deeper to see how “where” things are happening can often shed insight on “why” as well.

Writing conditional and aggregation data queries integrated nicely into specific workflows that you can expand as we dig deeper into the platforms that host the SQL consoles and windows.

In the next chapter, we will dig a little deeper into PostgreSQL by exploring pgAdmin in more detail and how to integrate PostGIS with QGIS.
