Formally known as DDD Service Project / Low-Code Project Java

Available in product edition: Professional

Introduction​

This project type supports designing all elements of the component with a high level of automation – from design, to develop, to deploy. The Solution Designer lets you model all parts in a structured and organized way, offering rich documentation possibilities for most of these elements with e.g., auto-generated UML diagrams to visualize the design model. This project type offers full automation support for code generation, resulting in up to 70% of the needed code. Meaning, you can fully concentrate on adding the needed business logic for the solution to solve the dedicated business problem.
