Course Description
This course teaches you how to leverage PostgreSQL to handle date and time data. You'll learn about functions and calls to help you parse through and manipulate this data, make calculations, and use window functions.
You’ll learn about various date and time data types and how to convert between them, manipulate their granularity, and perform calculations, including aggregations, partitioning, and running averages. These insights will help you add value to existing time series data.
You'll apply these techniques to real-world data to analyze temperatures, look at train schedules, and review how the popularity of news articles can change over time.

Working with Time Series
It’s time to get granular. In this chapter, you’ll learn how to set the granularity of your time series reports. You’ll then get to grips with adding, subtracting, and aggregating as you discover how to analyze time series data.
3
Using Window Functions to Analyze Time Series Data
In this chapter, you’ll work with window functions. You'll begin learning about partitions and partitioning and how they work with window functions. You'll be able to find the top items when ranking your data.
4
Calculating Running Totals and Moving Averages
In the final chapter, you’ll level up your skills by calculating the running total, running average, and even moving average to enhance your time series analysis.
