FlameRobin is a piece of open-source software that's based on a solid core somewhat modernised and made for managing databases of all stripes. It is specifically designed for use with the Firebird database another piece of open-source software. In fact FlameRobin itself is designed to work only off of open-source code.
What You Can Manage To Do
It thus takes full advantage of the tools offered by Firebird itself. It provides extensive rollback features saving a database's history in an efficient and useful fashion. It has sanity checks for actions that would be obviously (or less obviously) unwise. Where it's needed to do so Firebird can be extended and as long as FlameRobin is modified to match both tools are quite extensible. Obviously understanding Firebird's intricacies can be a little daunting for a novice programmer running their own server but for power users or software businesses looking for an alternative (and secure) RMDBS these two pieces of software pair together exceptionally well. After all they're designed to.
For Those In The Know
It's hard to talk about FlameRobin itself without talking about Firebird. The program itself is fairly competent with an interface organised along the top row in a mostly sensible fashion though it takes some learning compared to other database managers. Generally speaking if you already use a Firebird database or plan to this is the software you should be using to manage it.
