From a Firebird user, who wishes to remain anonymous :-)

You can SQL-ize almost any slogan by prefixing it with "SELECT" or "JOIN",
as in: JOIN the Database Legend

Re "legend", do a past/now/future timeline in describing the "legend", as in:

* For over 20 years (?does two decades sound better?) Interbase/Firebird
has lead the database world with first to have...

feature list, including: multi-generational architecture so readers never
block writers and writers never block readers

* Today fb is open source and supports Windows, Linux, Solaris, FreeBSD...

feature list, including: an embedded version to put your application on a
USB memory stick

* Tomorrow Firebird 3.0 "The Sequel". Jim Starkey, the original author of
Interbase, etc. for 64-bit support and the multiple core architectures of
upcoming CPUs.
other targeted features...
