This document summarizes myths about the Firebird database. It addresses myths that Firebird is only for small databases, is not widely used, and lacks support for multi-core CPUs. It notes that Firebird supports databases over 450GB, has millions of downloads and users, and supports multiple architectures including for heavy loads and multi-core servers. Firebird also has an active development community, regular releases over 20 years, and interfaces for many programming languages beyond just Delphi/C++Builder.
