Model-Driven Development of Versioning Systems: An Evaluation of Different Approaches

This paper analyzes the domain of versioning systems and compares three approaches to generating such systems from models. In the first approach, we define a domain-specific modeling language as a lightweight extension of UML and use templates to generate a middleware-based versioning system. In the second approach, we define a domain-specific data definition and manipulation language that can be embedded in versioning system applica-tions and map this language to SQL. In the third approach, we assemble the specification of a versioning system in Executable UML using model transformations. The presented approaches are evaluated from the perspective of developer productivity and performance of generated systems
