This course explores the hopes, myths, and reality of "zero code" systems, aiming to help business owners achieve systems that can be modified without the need for coders. The course covers various tools and approaches such as BPMN, DSLs, Drools, and in-house solutions. The teaching method includes sharing the instructor's experiences, discussing the potential for success, and presenting a project called Nussknacker. The course is designed for business owners, project managers, and individuals interested in real-time stream processing and technologies like Kafka, Flink, and React.
