What it does
This class handles the persistence (saving, updating, deleting) of catalog product attributes to the database, specifically managing website-scoped and global-scoped attributes.
Developers use this class when working with EAV attribute operations for catalog entities, ensuring attributes are saved correctly based on their scope configuration (global, website, or store view).
