Terminology Question: Intention and Extension

In the early days of the relational model, the words *intention* and "extension* were used respectively to mean *query* and *response*. That is, an SQL (or other database language) query represented your *intention*, that which defined what you wanted to retrieve. What the RDBMS delivered to you was the corresponding *extension*. (Kind of like the definition of something and the thing itself.)

Is this usage (query = intention, response = extension) used today? If not, what are the common terms used for query and response, and how are the terms *intention* and *extension* used now? Received on Sat Apr 05 2008 - 12:05:42 CDT
