Generic and Domain-Specific Model Refactoring using a Model Transformation Engine
نویسندگان
چکیده
Refactoring is an essential approach toward improving the internal structure of a software system while preserving its external behavior. Traditional refactoring techniques have focused on the implementation stage, with source code as the primary artifact of the refactoring process. However, a recent trend is to apply the concepts of refactoring to higher levels of abstraction. Consequently, model refactoring is emerging as a desirable means to improve design models using behavior-preserving transformations. This chapter describes a practical approach toward implementing model-level refactoring. A model transformation engine has been developed and provides a generalized underlying refactoring tool for manipulating models. A model refactoring browser is integrated within the model transformation engine to enable the automation and customization of various refactoring methods for either generic models or domain-specific models. A result of this work is the capability to perform model refactoring rapidly using user-specified transformation rules.

متن کاملAchieving Practical Genericity in Model Weaving through Extensibility
Many tasks in Model-Driven Engineering (MDE) involve cross-cutting model modifications that are bound to certain conditions. These transformation tasks may affect numerous model elements and appear in different forms, such as refactoring, model completions or aspectoriented model weaving. Although the operations at the heart of these tasks are domain-independent, generic solutions that can easi...
متن کاملA Generic Technique for Domain-Specific Visual Language Model Refactoring to Patterns
As the popularity of domain-specific visual languages (DSVLs) grows, concerns have arisen regarding quality assurance and evolvability of their meta-models and model instances. In this paper we address aspects of automated DSVL model instance modification for quality improvement based on refactoring specifications. We propose a graph transformation-based visual language approach for DSVL author...

متن کاملA Domain Specific Transformation Language
Domain specific languages (DSLs) allow domain experts to model parts of the system under development in a problem-oriented notation that is well-known in the respective domain. The introduction of a DSL is often accompanied the desire to transform its instances. Although the modeling language is domain specific, the transformation language used to describe modifications, such as model evolution...
