Google Cloud Platform’s BigQuery service allows you to create, manage, distribute, and query data, as well as execute data warehousing, analytics, and machine learning. BigQuery enables users to analyze massive volumes of data while utilizing cloud-based parallel computing to meet your big data needs.

This Google solution, in contrast to most other cloud-based data warehouses, requires minimal to no maintenance. As a result, you may use Google’s Data Warehouse from any place that has connectivity to Google Cloud. The platform can also now gather and process more data from a larger number of sources after recently updating its data capabilities.


Types of Queries in BigQuery

Saved queries are classified into three kinds, and the IAM rights necessary to create, view, edit, share and remove saved queries are described below:

  • Private Queries
    Private stored queries are only available to the user who created them. No additional permissions are required to create private saved queries. A private query may be saved in any project, but only you can read, change, or remove it.
  • Public Queries
    Creating public queries requires no special permissions. A public query may be saved in any project, but only you can change or delete it. A public stored query can be viewed by anybody who has the URL.
  • Project Level Queries
    Only the project members or users with managed permissions can see project level inquiries. There are specific IAM permissions that give users the ability to create, view, delete, and update saved queries, which can be found on Google’s documentation.
