Rapid Realization of Executable Domain Models via Automatic Code Generation

Today’s generation of cloud-connected systems such as mobile and web-apps have high demands for reliability and sustainability. Agile methods benefit a lot from the evolving technology to satisfy those increasing demands. While automated testing helps to address reliability issues, other technologies such as prototyping and version management play a role as well. However, software development is labor-intensive, time consuming, error-prone and expensive. As-built systems often don't match designs and fail to meet requirements. The gap between design and implementation always exists as customers demand rapid release cycles with time constraints and limited resources. Our effort is focused on reducing this gap for service-oriented projects. This approach considers both technical strategies and agile methods, trying to streamline the progression from design to implementation at a relatively early phase, and then throughout the whole development lifecycle. Meanwhile, we attempt to shorten development schedule in both stages, and to eliminate the risks caused by evolutionary development. Automatic code generation has the potential to reduce above problems to a certain extent. This paper describes our efforts to enable rapid and continuous delivery while leveraging parallelism in development via automatic code generation - specifically making domain models instantly executable. We describe a code generator that has been built to enable parallel development of services. It uses UML class diagram to model the problem domain, then rapidly realize the domain model as a set of NoSQL database collections, automate the generation of common database access functions, and automate the wrapping of these database functions within a RESTful API. Several actual project instances have been built using this code generation approach. The results and lessons learned from these projects are also discussed in this paper. We also consider several common deployment scenarios (e.g. requirements for media-handling, security, scalability) to ensure the flexibility and reusability of the target source code for subsequent development iterations.
