How are Apex requests delimited?
All requests are delimited by the trigger, class method, Web Service, Visualforce page or anonymous block that executes the Apex code. If the entire request completes successfully, all changes are committed to the database. For example, suppose a Visualforce page called an Apex controller, which in turn called an additional Apex class. Only when all the Apex code has finished running and the Visualforce page has finished running, are the changes committed to the database. If the request does not complete successfully, all database changes are rolled back.
Can savepoints be used across trigger contexts?
References to savepoints cannot cross trigger invocations because each trigger invocation is a new trigger context. If you declare a savepoint as a static variable then try to use it across trigger contexts, you will receive a run-time error. Each savepoint you set counts against the governor limit for DML statements.
How are Transactions Useful?
Transactions are useful when several operations are related, and either all or none of the operations should be committed. This keeps the database in a consistent state. There are many business scenarios that benefit from transaction processing. For example, transferring funds from one bank account to another is a common scenario.
Example
This example shows how all DML insert operations in a method are rolled back when the last operation causes a validation rule failure. In this example, the invoice method is the transaction boundary—all code that runs within this method either commits all changes to the platform database or rolls back all changes.
