Goals form a declarative description of the desired end result of (part of) an orchestration. A goal-oriented orchestration language is an orchestration language in which these goals are part of the language. The advantage of using goals explicitly in the language is added flexibility in handling failures. In this paper, we investigate how goal-oriented mechanisms for handling failures compare ...

We combine the area of object-oriented speciication and object-oriented logic programming by indicating the translation of a speciication language into an enhanced logic programming language. The translation shows that in comparison to the programming language the speciication language ooers richer concepts. The background of our work is the development of rapid prototyping systems for object-o...

Most existing object-oriented database systems exploit a general purpose imperative object-oriented programming language as method deenition language. The use of such languages makes it diicult to analyze method properties and to optimize them. We believe that the use of an ad-hoc, set-oriented language can ooer some advantages, at least at a speciication level. In particular, such a language c...

Language learning strategies, “the techniques or devices which a learner may use to acquire knowledge” (Rubin, 1975, p. 43) or more pertinently “complex, dynamic thoughts and actions, selected and used by learners with some degree of consciousness in specific contexts” (Oxford, 2017, p. 48), have been widely researched and discussed for more than forty years since the mid-1970s. Shifting the fo...
