| Zusammenfassung: | Model-Driven Engineering (MDE) is a software engineering paradigm that
aims to increase the productivity of developers by raising the
abstraction level of software development. It envisions the use of
models as key artifacts during design, implementation and deployment.
From the recent arrival of MDE in large-scale industrial software
development – a trend we refer to as MDE in the large –, a set of
challenges emerges: First, models are now developed at distributed
locations, by teams of teams. In such highly collaborative settings, the
presence of large monolithic models gives rise to certain issues, such
as their proneness to editing conflicts. Second, in large-scale system
development, models are created using various domain-specific modeling
languages. Combining these models in a disciplined manner calls for
adequate modularization mechanisms. Third, the development of models is
handled systematically by expressing the involved operations using model
transformation rules. Such rules are often created by cloning, a
practice related to performance and maintainability issues.
In this thesis, we contribute three refactoring techniques, each aiming
to tackle one of these challenges. First, we propose a technique to
split a large monolithic model into a set of sub-models. The aim of this
technique is to enable a separation of concerns within models, promoting
a concern-based collaboration style: Collaborators operate on the
submodels relevant for their task at hand. Second, we suggest a
technique to encapsulate model components by introducing modular
interfaces in a set of related models. The goal of this technique is to
establish modularity in these models. Third, we introduce a refactoring
to merge a set of model transformation rules exhibiting a high degree of
similarity. The aim of this technique is to improve maintainability and
performance by eliminating the drawbacks associated with cloning. The
refactoring creates variability-based rules, a novel type of rule
allowing to capture variability by using annotations.
The refactoring techniques contributed in this work help to reduce the
manual effort during the refactoring of models and transformation rules
to a large extent. As indicated in a series of realistic case studies,
the output produced by the techniques is comparable or, in the case of
transformation rules, partly even preferable to the result of manual
refactoring, yielding a promising outlook on the applicability in
real-world settings. |
