**What is SQL?**\
\
In Google Cloud Platform (GCP), SQL refers to the managed relational database services provided through Cloud SQL. Cloud SQL supports popular SQL-based databases like MySQL, PostgreSQL, and SQL Server, allowing users to set up, maintain, manage, and administer relational databases in the cloud. It offers automatic backups, scaling, patch management, and high availability, making it easier to run and manage SQL databases without handling the underlying infrastructure.
