In this paper two external schema generation algorithms are presented. These algorithms are defined in the framework of the new external schema definition methodology for OODBs put forward in (Samos, 1995); they generate an external schema from a set of classes selected from those existing in an external schema definition repository. Their main characteristic is that they avoid the generation o...

Problem framing is recognised as an important new technique for describing the problem context in order to identify and then apply the most appropriate modelling and description techniques to developing different kinds of software system. Jackson has proposed five distinct problem frames and variants on them. However, Jackson makes no claim that this is an exhaustive list. In order to better mo...

The project management discipline is expanding within many engineering activities. This discipline can facilitate strivings toward successful accomplishment of an engineering project. Therefore, many academic institutes teach the “project management” program. This study presents a novel approach that educates engineering students to become successful project managers based on contextual learnin...
