001 (pronounced "double oh one") is a fully integrated systems engineering and software development environment. It can be used to define, analyze and automatically generate complete, integrated, and fully production-ready code for any kind or size of software application with significantly lower error rate and significantly higher reusability than with traditional approaches. Since 001 has an open architecture it can be configured to generate (or interface to) systems at all levels including for hardware platforms, software platforms, programming languages, databases, operating systems, internet systems, embedded systems, communication protocols, GUI's and legacy code of choice.
