What Does Query Mean?
A query is a request for data or information from a database table or combination of tables. This data may be generated as results returned by Structured Query Language (SQL) or as pictorials, graphs or complex results, e.g., trend analyses from data-mining tools.
Techopedia Explains Query
For a machine to understand a request for information in the first place, the query must be written according to a code known as query language. For example, if you go to a bank and ask “Can I have an espresso?” the teller might be puzzled.
