In many data management environments, after you modify a record's values, which operation are you considered to have performed before issuing a command to save or commit the changes?

Introduction / Context:
Most database front-ends and DBMS clients distinguish between changing data in memory (or a pending state) and making those changes permanent on disk. This question tests the correct terminology for modifying an existing record's field values before committing the transaction or saving the row.

Given Data / Assumptions:

• You have altered one or more column values of an existing record.
• The environment may require an explicit save/commit to persist the change.
• We are not deleting the row or changing physical storage structures like indexes.

Concept / Approach:

Changing the values of a record is an update. In SQL, this corresponds to the UPDATE statement. Many tools cache the change until the user clicks Save or until a COMMIT is issued; until then it may be pending or uncommitted. The logical operation remains an update, not a delete or indexing action.

Step-by-Step Solution:

Verification / Alternative check:

In SQL logs or UI audit trails, the change is recorded as an UPDATE statement; a subsequent COMMIT finalizes it for durability.

Why Other Options Are Wrong:

Delete: Removes rows rather than changing values.

Index / Sort key: Concerned with access paths and ordering, not data modification.

None: Incorrect because the correct term is well-established.

Common Pitfalls:

Assuming autosave always occurs; many systems require explicit commits to avoid losing updates on rollback.

Final Answer:

Update
