QVT Traceability: What does it really mean?
نویسندگان
چکیده
Traceability in Model Transformation languages supports not only post-execution analysis, but also incremental update and coordination of repetition. The Query/View/Transformation family of languages specify a form of traceability that unifies high and low level abstraction in declarative and imperative transformation languages. Unfortunately this aspect of the QVT specification is little more than an aspiration. We identify axioms that resolve the conflicting requirements on traceability, and provide a foundation for resolving further issues regarding equality, transformation extension and mapping refinement.

متن کاملOil, petroleum, hydrocarbon — words that have become popular in our modern-day vernacular, but what do they really mean to us
Oil, petroleum, hydrocarbon — words that have become popular in our modern-day vernacular, but what do they really mean to us? What is oil? How does it form? Where do we find it? How do we look for it? Do we really need it? Why? Are we actually running out? Does its use damage our environment? These are all good questions, but some of the answers are not quite so simple. This issue of Rock Talk...
