 Learning Objectives

Why you should attend this workshop on Google BigQuery:

BigQuery is a serverless, highly scalable and cost-effective enterprise data warehouse that is available on multiple cloud platforms, including the Google Cloud Platform. Google's enterprise data warehouse was designed to make large scale data analysis accessible to everyone, from data-savvy profiles like data engineers and data scientists, to less technical profiles like report / dashboard builders and business analysts.

We'll show you how BigQuery can help you get valuable insights from your data with ease, whether it is log data from thousands of retail systems or IoT data streams from millions of vehicle sensors.

If your company is on the road to become data-driven, it is probably analysing big volumes of data, sitting in a data warehouse architecture or Hadoop clusters, either on-premise or in the cloud. Very quickly, you'll run into problems with data and usage growth, scalability, maintenance, upgrades and licensing costs. If you have trouble finding the necessary skills and budgets for managing a scalable setup, then a cloud data platform like BigQuery may be the answer. Say goodbye to data silo's, huge licensing costs, infrastructure maintenance and upgrades, and start analysing all of your data.

Because BigQuery is a serverless compute architecture that decouples compute and storage, this enables diverse layers of the architecture to perform and scale independently, which also gives data developers flexibility in design and deployment.

This two-day workshop shows you how and why BigQuery has become one of the best platforms for analyzing and learning from data. Powerful features include Standard SQL, deeply nested data, user defined functions in JavaScript and SQL, geospatial data, integrated machine learning, URL addressable data sharing, federated queries, integration with other Google products, ... just to name a few. All these features allow you to implement self-service ad hoc data exploration that many users demand.

During this workshop, we will use Google's Colaboratory, or 'Colab' for short, as development environment. This allows you to write and execute SQL asnd Python in your browser without installing and configuring any software, while having free access to GPUs and really easy sharing. Think about Colab as a Jupyter notebook stored in Google Drive. Whether you're a student, a data scientist or an AI researcher, Colab can make your work easier. Watch Introduction to Colab to find out more.

For this workshop, we will set up a personal BigQuery / Colab development environment, where you can execute the prepared exercises, in the browser, and experiment with your own code and data. Many exercises will be based (with permission) on the fantastic Google BigQuery: Definitive Guide book by Valliappa "Lak" Lakshmanan.

Google BigQuery was recognised by Gartner as a leader in the Magic Quadrant for Cloud Database Management Systems (23 November 2020).


This course assumes that you are interested in data, have some knowledge of SQL and understand the basics of databases and data warehouses. There is no need to know the Google Cloud Platform, Colab or Python to attend this course.

Target Audience:

We are aiming this workshop at data engineers, data analysts, data scientists and developers of data-driven applications, but we will also illustrate BigQuery's power in machine learning and data visualisation, while mentioning the security and governance of using a cloud-based data warehouse.
