I'm a web application developer myself, so I'm aware of how passwords are stored in back-end databases using salted hashes.

Performance can also be enhanced if a continuous connection is maintained to the back-end database throughout the session rather than opening and closing it for each table access.

Informix was looking to break into the desktop software market with products that could link to their back-end databases, and Wingz seemed like a good fit.

The server translates the data to some combination of physical SQL and sends them to the back-end databases.

The back-end database of Outlook Express changed completely, and became dependent on WinFS to store its email.
