What is Commit in Laravel, and what role does it play in a real application?

What is Commit in Laravel, and what role does it play in a real application? In Laravel, commit should be understood as part of a larger application architecture rather than as an isolated API call. Commit permanently applies successful changes when all operations in the transaction have completed. A strong understanding includes its purpose, the layer where it belongs, the data or request flow it affects, and the situations where another mechanism may be more appropriate. Practical context: Database transactions allow multiple related database operations to commit together or roll back together when an operation fails. The specific focus here is commit: Commit permanently applies successful changes when all operations in the transaction have completed. This question is designed to test not only terminology, but also how the concept fits into Laravel's request, application, database, security, or deployment workflow.
