Reverse engineering of relational databases: Extraction of an EER model from a relational database

... These have been demonstrated to be implementable in a knowledge-based system; a working prototype system which does so is briefly discussed. In addition, cases in which human input is required are also clearly identified. This research ...

Theoretical Aspects of Schema Merging

... the most important of which is that schemas are placed in a partial order that has bounded joins. This means that the merging ... that the merge of schemas is independent of the order in which they are considered --- a property not possessed by existing ...

Composing Schema Mappings: Second-Order Dependencies to the Rescue

... effect as applying successively the two schema mappings. In this paper, we give a rigorous semantics to the composition of schema ... We first study the important case of schema mappings in which the specification is given by a finite set of source-to-target ...

Weaving Models with the Eclipse AMW plugin

... 100 - 499 The basic assumption in model engineering (MDE) is to consider models as first class entities. One of the most important kinds of models in MDE approaches are transformation models. Transformation models define ...
