 Firebird is a relational database offering many ANSI SQL-99 features that
 runs on Linux, Windows, and a variety of Unix platforms. Firebird offers
 excellent concurrency, high performance, and powerful language support
 for stored procedures and triggers. It has been used on production systems
 under a variety of names since 1981.

 This allows for good scaling on multi-processor machines without consuming
 too much operating system resources.
