This is a Database related question:

To make permanent all changes made to a table, the user needs to commit these changes. The instruction that allows a user to record these changes permanently into the database is the COMMIT statement. The basic syntax of this statement is this: COMMIT [WORK]; Notice that the keyword WORK is optional.

Given these facts, answer the following questions: 1. If work is committed, but is incorrect, can it be changed?

2.What are the implications for users and for system developers?
