Query by Example is a database query language for relational databases. It was developed at IBM in the 1970s. The development of SQL ran in parallel. Users get a visual schema of the database, which they edit with a special editor. Query by example was developed for the user who only uses databases occasionally, and who does not want to learn a complex language such as SQL. Many database systems still use systems resembling query by example today.
