What it does
This collection class is used to retrieve and work with multiple quote (shopping cart) records from the database.
Developers use this to fetch, filter, and manipulate sets of quotes, such as getting all active quotes, quotes by customer, or abandoned carts.
It extends Magento's version control collection to provide database query capabilities specifically for quote entities.
