Which query method allows users to select tables and fields in a database by pointing and clicking?

Query by Example (QBE) is the correct choice because it is specifically designed to provide an intuitive way for users to retrieve data from a database. In QBE, users can indicate the tables and fields they want to work with by visually interacting with the database interface. This is typically done through a graphical user interface, where users enter example criteria regarding the data they wish to see, usually in a form that resembles a spreadsheet. This ease of use makes QBE particularly user-friendly for those who may not be familiar with programming or complex query languages.

Structured Query Language (SQL), while powerful and widely used, requires users to write queries in a specific syntax, which can be daunting for those who lack technical expertise. Data Definition Language (DDL) focuses on defining the structure of the database, such as creating or altering tables, rather than querying them for data. Data Model Language involves defining models that describe the logical structure and organization of data but does not facilitate direct data selection through point-and-click methods. Thus, QBE stands out as the method that allows for simple, intuitive data querying through a point-and-click approach.
