Introduction to Google Cloud BigQuery

Course description
BigQuery is a popular data warehouse service that allows you to easily work with petabytes of data.  Learn how to quickly get up to speed with BigQuery and start querying and analyzing data efficiently using the BigQuery graphical user interface, command line utilities, and even programming languages.  If you are familiar with basic database concepts, like tables, you are ready to start learning one of the most important data analytics platforms available. While some courses will focus just on using SQL with BigQuery, this course starts with the basics of signing up for Google Cloud and working the BigQuery graphical user interface (GUI), introduces SQL for BigQuery, and then moves to loading data and working with BigQuery using the command line and Python.  Perhaps most importantly, you will learn how BigQuery is different from other databases and how to use that knowledge to use BigQuery efficiently and cost effectively. You will learn how to explore data, tables, and datasets. Write queries efficiently using BigQuery hints and formatting helps.  Work with SELECT statements, including creating FROM, WHERE, GROUP BY, HAVING, and ORDER BY clauses to create queries that answer driving questions you have about your data.  If you are not familiar with working with multiple tables and using joins, that's no problem, you will learn that in this course. Use features of BigQuery designed to make you more productive, like Saved Queries, Exporting Data, and Execution Details that help you improve the performance of your queries. Learn how to create tables and data sets and load data into BigQuery directly and by using Cloud Storage, Google Cloud's large scale object storage system. While the graphical user interface, known as the BigQuery console, is an excellent tool for interactive work with BigQuery, sometimes we need to run the same queries or operations repeatedly to generate reports or download data. In this course you will learn about the bq command line utility that lets you query data and work with datasets from the command line.  If you prefer to work with Python or other programming languages, you can use the BigQuery client libraries for running queries and other jobs right from your programs and scripts. You don't even need to have Python installed on your device because we'll use CoLab, a free Google service for working with Python notebooks. Quizzes and assignments in this course allow you to check your understanding as you progress through the course by answering questions and writing queries. To use BigQuery effectively though, you need to understand how BigQuery is designed. Building a data warehouse and designing data models in BigQuery is fundamentally different than building and modeling in relational databases like Oracle, SQL Server and PostgreSQL. In this course, you will learn about BigQuery's architecture and how it influences how we structure and query data. Learn insights from an instructor with decades of experience in working with data.
