Final answer:
A Find Unmatched query is used to find the rows in one table that do not have a match in the other table. It is commonly used in database management systems.
Step-by-step explanation:
A Find Unmatched query is used when you want to find the rows in one table that do not have a match in the other table. This type of query is commonly used in database management systems to identify missing or inconsistent data. It can help identify records that need to be corrected or updated.
For example, let's say you have two tables: Customers and Orders. To find customers who have not placed any orders, you can use a Find Unmatched query to compare the records in the Customers table with the records in the Orders table.
Using a Find Unmatched query can help you identify data discrepancies, improve data integrity, and ensure that your database is accurate and up-to-date.
