Query By Example (QBE) is best described as

• A. A text-based language
• B. A graphical way to ask questions
• C. A type of index
• D. A data encryption method

Answer: (B)

Query By Example lets you build database queries by filling in a visual grid instead of writing code. You see the table fields laid out as columns and you enter example values or constraints in the criteria area. The system then interprets those examples and generates the actual query to fetch the matching records and display the requested fields. For instance, entering a specific last name and a city in the grid translates to a condition like LastName = 'Smith' AND City = 'New York' behind the scenes. You can also use operators or wildcards in the grid to express ranges or patterns. This graphical approach is designed for users who understand the data but don’t know SQL, making it a straightforward way to ask questions about the data.
