BigQuery Soccer Data Ingestion
GSP848
Overview
Information access uses multiple formats, and BigQuery makes working with multiple data sources simple. In this lab you will get started with sports data science by importing external sports data sources into BigQuery tables. This will give you the basis for building more sophisticated analytics in subsequent labs.
The data used in this lab originates from the following sources:
- Pappalardo et al., (2019) A public data set of spatio-temporal match events in soccer competitions, Nature Scientific Data 6:236, https://www.nature.com/articles/s41597-019-0247-7
- Pappalardo et al. (2019) PlayerRank: Data-driven Performance Evaluation and Player Ranking in Soccer via a Machine Learning Approach. ACM Transactions on Intelligent Systems and Technologies (TIST) 10, 5, Article 59 (September 2019), 27 pages. DOI: https://doi.org/10.1145/3343172
In this lab, you will learn how to:
-
Upload files from Google Cloud Storage (GCS) into BigQuery tables using the Cloud Console.
-
Use the Cloud Console to access information derived from BigQuery tables.
-
Understand how to write queries on the uploaded tables.
Task 1. Open BigQuery
The BigQuery console provides an interface to query tables, including public datasets offered by BigQuery.
- In the Cloud Console, from the Navigation menu select BigQuery:
- The Welcome to BigQuery in the Cloud Console message box opens. This message box provides a link to the quickstart guide and the release notes.
- Click Done.
- The BigQuery console opens.
In this section the BigQuery interface was used to access the console. The console provides a convenient way to add information to a dataset. BigQuery uses tables to represent data in a structured way.
In the next section learn more about BigQuery and how to create custom tables.
Task 2. Create custom tables
In this section, you will create a dataset. The dataset is used to add data to the project. Datasets utilize tables and views to help control access to data within a project.
- In the BigQuery console, observe the Explorer section.
- Click on the View actions icon next to your project ID and select Create dataset.
- On the Create dataset page fill in the following:
Field | Value |
---|---|
Dataset ID | soccer |
Data location | us (multiple regions in United States) |
Default table expiration | Default |
- The BigQuery Create dataset screen will display information similar to below:
- Click Create dataset at the bottom of the panel.
Click Check my progress to verify the objective
In this section a new dataset was created using BigQuery. During this process, BigQuery needs to know where to store the information to be created. It also provides the option to include customer managed encryption, if required.
In the next section learn how to populate the created dataset with JavaScript Object Notation (JSON) a common data format.
Task 3. Load JSON Data
Now you will load the tables created previously with soccer data into the dataset.
BigQuery provides support for a number of import formats.
In this lab use JSON with the dataset created in the previous section.
-
Create a table by clicking on the View actions icon next to your
soccer
dataset in the Explorer section. -
Select Create table.
In the following section use the default values for all settings unless otherwise indicated. The data is stored in a public Google Cloud Storage (GCS) bucket.
- On the Create table page add the following information:
Field | Value |
---|---|
Source | Google Cloud Storage |
Select file from GCS bucket | spls/bq-soccer-analytics/competitions.json |
File format | JSONL (Newline delimited JSON) |
Table name | competitions |
Schema | Check the box marked Schema Auto detect
|
gs://
to be applied.
- The BigQuery Create table screen will display information similar to below:
- Click Create table.
- Wait for BigQuery to create the table and load the data.
- A pop up notification message saying "competitions" created is displayed.
- The table will show up after the data is loaded.
- Repeat the steps above for the other JSON data to be ingested.
GCS bucket file | Table name |
---|---|
spls/bq-soccer-analytics/matches.json | matches |
spls/bq-soccer-analytics/teams.json | teams |
spls/bq-soccer-analytics/players.json | players |
spls/bq-soccer-analytics/events.json | events |
- Once the tables are created the display will be similar to below:
Click Check my progress to verify the objective
In this section new tables were created using BigQuery. During this process, BigQuery used Cloud Storage as the source for the JSON files. Cloud Storage provides a good intermediate storage option for object files.
In the next section learn how to populate the created dataset with a comma-separated values (CSV) file, that is another common data format.
Task 4. Load CSV data
In this section, load another table of soccer data into the dataset. The load process will this time be sourced from a comma-separated values (CSV) file stored in Cloud Storage.
- Create a table by clicking on the View actions icon next to your
soccer
dataset in the Explorer section, and select Create table.
Use the default values for all settings unless otherwise indicated.
- On the Create table page add the following information:
Field | Value |
---|---|
Source | Google Cloud Storage |
Select file from GCS bucket | spls/bq-soccer-analytics/tags2name.csv |
File format | CSV |
Table name | tags2name |
Schema | Check the box marked Auto detect |
- The BigQuery Create table screen will display information similar to below:
- Click Create table (at the bottom of the window).
- Wait for BigQuery to create the table and load the data.
A pop up message will appear saying "tags2name" created.
- The table will show up after the data is loaded.
Click Check my progress to verify the objective
In this section a new table was created using BigQuery. During this process, BigQuery used Cloud Storage as the source for the CSV file. Cloud Storage provides a good intermediate storage option for object files.
Task 5. Preview tables
- In the left pane, select soccer > competitions in the navigation panel.
- In the Details panel, click the Preview tab.
- Click through the other uploaded tables from the navigation panel.
- Check the Schema, Details, and Preview tabs to learn more about the data in each table.
BigQuery provides a convenient way to store data previously held in a variety of formats. To learn more about data ingestion techniques for BigQuery read Choosing a data ingestion method.
In the next couple of sections learn how to query the datasets created in BigQuery.
Task 6. Query Player data
Now that you've loaded data into your tables, you can run queries against it. Next, create a query that retrieves the top 10 tallest defenders (for whom height is available) in the players table.
-
In the query Editor, click "+" (Compose new query) icon.
-
Copy and paste the following query into the query Editor:
- Click Run. The results are displayed below the query window.
Click Check my progress to verify the objective
Understanding how to perform queries in BigQuery is essential. Running queries in BigQuery provides a simple interface to extract powerful data insights.
Task 7. Query events data
Create a query to retrieve counts of all event types that are found in the events table.
-
Copy and paste the following query into the query Editor:
- Click Run. The results are displayed below the query window.
Click Check my progress to verify the objective
Being able to capitalize on stored data to establish trends and patterns presents an opportunity to deliver real benefit to end users. In the next section test your understanding of what you have learned in this introduction to BigQuery.
Task 8. Pop quiz
Test your understanding of BigQuery by completing the short quiz on the topics covered in this lab.
Congratulations!
You have successfully uploaded files stored in Cloud Storage into tables in BigQuery and learned how to compose queries to extract data from the tables.
