Rollback behaviour in UOW

Implicit Rollback Behavior: If an operation (e.g., insert, update, upsert) on any record (like Contact) fails, the entire transaction is rolled back automatically. Salesforce's built-in transaction handling ensures no partial changes are committed if an error occurs. No Need for Savepoints: Unlike manual transaction control (e.g., savepoints and rollbacks), the UoW pattern abstracts this complexity. Developers do not need to explicitly define savepoints, as UoW handles transaction integrity.
