querier

This term is primarily used in technical or formal contexts. In general conversation, people typically use "questioner" or "inquirer," as "querier" can sound overly stiff or archaic when referring to a person. It carries a connotation of a systematic or formal search for information rather than a casual curiosity.

In the realm of computer science and database management, the term is a standard technical designation. It refers specifically to the entity—whether a human user or an automated software agent—that initiates a query. In this context, it is a neutral, functional term devoid of the social connotations associated with questioning a person.
