QC meaning in Database Management ?

Questionable Content (sometimes abbreviated as QC) is a slice-of-life webcomic written and illustrated by Jeph Jacques. It was launched in August 2003 and as of April 2021 reached its 4,500th comic. The plot originally centered on Marten Reed, an indie rock fan; his anthropomorphized personal computer Pintsize; his roommate, Faye Whitaker; their mutual friend, Dora Bianchi; and their neighbor Hannelore Ellicott-Chatham. However, over time a supporting cast of characters has grown to include employees of the local coffee shop, neighbors, and androids. QC's storytelling style combines romantic melodrama, situational comedy, and sexual humor, while considering questions of relationships, sexuality, dealing with emotional trauma, and artificial intelligence and futurism.

Jacques has made his living exclusively from QC merchandising and advertising. By 2004, Jacques could support himself and his then-fiancée based on income from merchandise and advertising sales.
