Read Committed Isolation

Problem

A transaction is reading data, but another transaction is actively modifying it and hasn't committed yet. If you read that uncommitted data, you might see a state that is eventually rolled back (Dirty Read). You want to ensure you only read finalized data. Write a query that outputs behavior with the value: "Read Committed guarantees you only read data that has been successfully committed by other transactions."

Database Schema

This problem acts as a scratchpad. You will write your own DDL/DML or conceptual queries, so there is no predefined schema.
