Query-Based Views (Q-Views) provides the Views-like functionality of generating reports or content feeds, but starts the process with a raw SQL query. In Views, the query is constructed through setting up configuration, but in Q-Views you supply the query directly. This can be a more rapid, reasonable solution in some situations. Q-Views is very AJAX-y by default, with ajax-based pagination and searching, which also means rapid browsing through data. Views is much more mature, so it's encouraged that you use Views when you can, but Q-Views can provide a lot of functionality with low configuration overhead when you would normally build a feed or report outside of Views.
