Prefácio
Ser pioneiro em uma nova categoria de sistemas de software é o sonho de muitos engenheiros de software.

Historicamente, o processamento de fluxos era considerado difícil e apenas as grandes organizações com equipas dedicadas de especialistas em fluxos o podiam dominar. O mesmo acontecia com o processamento de dados e a computação há 50 anos, antes da invenção do SQL e dos sistemas de bases de dados relacionais para permitir que utilizadores não técnicos trabalhassem com dados armazenados em sistemas informáticos.
