Microsoft Query by Example (QBE) is a method of creating database queries using examples based on a text string, the name of a document or a list of documents. The QBE system converts the user input into a formal database query. This approach allows the user to perform powerful searches without the need of having to learn a more formalized query mechanism such as Structured Query Language (SQL). It is dervied from Zloof's original Query By Example QBE implemented in the mid 1970's at IBM's Research Centre in Yorktown.
