The Database API in Drupal is a set of functions used to interact with a database. It provides a unified interface for accessing and manipulating data stored in a database, regardless of the type of database being used. The Database API is designed to be flexible and extensible, allowing developers to create custom database queries and access data in a variety of ways. It also provides a consistent way to access data from different databases, making it easier to switch between different databases without having to rewrite code.
