Data is fantastic, but Big Data is even better. With big data, you get a broader scope of research, which ultimately goes a great way in informed decision-making. However, getting your hands on large datasets is not as easy as it seems. A myriad of factors come into play, making it extremely difficult for you to access such information. For instance, you need ample storage to host this data which is another expensive feat. Furthermore, you need analytics tools to run over the dataset and get accurate information. In fact, without credible analytic tools, you just have a bunch of information you cant make good use of. 

It is no secret that data is precious, and the more you have, the better. However, with extensive data comes several complexities that make a scientist’s job even more complicated. The future with Big Data may sound bleak, but that is not the case with BigQuery Public Datasets. With these tools, you can easily explore the world of open data. So what exactly are BigQuery Public Datasets

In this article, you will get to know about some BigQuery Public Datasets available for you to use. 

Introduction to BigQuery Public Datasets

In simple terms, a public dataset is any sort of dataset stored in Bigquery. It is then made available to users through the Google Cloud Public Dataset Program. You can then access these datasets and integrate them into your applications as you desire. It is worth noting that Google handles storage expenses for these datasets and allows access via a project. As the end-user, you will only be required to pay for the queries you perform on the data. You need only use SQL or standard SQL queries. You can access this information via the Cloud Console

For more information on the topic at hand, you can visit the BigQuery Public Datasets page. You will realize that there are over 40 public datasets available for you to utilize. Furthermore, there is a brief but comprehensive explanation of the datasets. This way, you can better understand the structure of the dataset before you begin the querying process.

How To Use Public Dataset in Bigquery 

To use a public dataset in BigQuery, follow these steps:

  1. Sign in to Google Cloud: If you’re new to Google Cloud, create an account to evaluate how the products perform in real-world scenarios.
  2. Select or create a Google Cloud project: On the project selector page, make sure that billing is enabled for your Google Cloud project.
  3. Navigate to the BigQuery page: In the Google Cloud console, go to the BigQuery page to begin.
  4. Open a public dataset: In the Explorer pane of the BigQuery page, click +Add. In the Add dialog, search for public datasets, and then click Public Datasets to access datasets in the public project bigquery-public-data. This will provide you with the BigQuery public datasets list.

With this, you’ve seen how to add public dataset in BigQuery.

  1. Compose a new query: If the Editor field is not visible, click Compose new query. In the Editor field, you can enter your SQL query.

  1. Run the query: After composing your query, click the Run button to execute it and view the results.
  2. Clean up: To avoid incurring charges to your Google Cloud account for the resources used in this quickstart, you can delete the project, which will also delete any datasets or tables you’ve created.

Remember, Google BigQuery public datasets are available at no charge for storage, and you pay only for the queries that you perform on the data. The first 1 TB of data processed per month is free.

Here’s an example query you can run on a public dataset:

SELECT name, SUM(number) AS total
FROM `bigquery-public-data.usa_names.usa_1910_2013`
GROUP BY name
ORDER BY total DESC
LIMIT 10;

This query will retrieve the top 10 most common names from the USA Names dataset, which is part of the BigQuery open datasets
