Organization-oriented analysis acts as the key step and foundation in building organization-oriented methodology (OOM) to engineer multi-agent systems especially open complex agent systems (OCAS). A number of existing approaches target OOM, while they are incompatible with each other, and none of them is available as a solid and practical tool for engineering OCAS. This paper summarizes our inv...

Many enterprise systems employ both object-oriented middleware (OOM) and message-oriented middleware (MOM). However, support for the integration of object and messaging services, in particular for transaction processing across object and messaging components, is very limited. In this paper, we introduce the concept of Dependency-Spheres (D-Spheres), a global transaction context for distributed ...

The advantages of object-oriented (OO) programming are well-known. Nevertheless, distributed OO middleware systems (OOM) such as CORBA, DCOM or Java RMI have not been widely adopted for the developing of Internet applications. Developers seem to perceive OOMs as overcomplex, proprietary or incompatible with current WWW development practices. Recognizing these difficulties more WWW-friendly prop...

Object-Oriented Models (OOM) are widely used in ModelDriven Engineering (MDE). As a complement, OCL constraints are used to specify business rules and detailed aspects of the business domain. Automatically co-evolving OCL constraints w.r.t. the evolved OOM is challenging since alternative resolutions can be applied but also a resolution cannot be applied to any arbitrary constraint. In this pap...

The authors introduce a didactic system for object-oriented modelling (OOM) as a new and flexible learning concept for informatics education and outline a development methodology which is in evaluation. With the aim to improve the quality and individualization of lessons the following components of a didactic system have been identified so far: and-or-graphs for the representation of the knowle...

We aimed to microscopically examine whether Caucasian eyelids demonstrate overriding of preseptal orbicularis oculi muscle (OOM) over the pretarsal OOM in both lower and upper eyelids. Full thickness sections of 13 lower eyelids and 11 upper eyelids from seven Caucasian cadavers were examined. In the lower eyelids, all 13 specimens demonstrated clear overriding of preseptal OOM over the pretars...

In Germany the results of the international PISA study disclosed a demand for an increase in the quality and an improvement in the comparability of educational results. In the subjects German, maths and first language (i.e. English) this demand already resulted in the development and publication of first educational standards. With the aim to prepare educational standards for the Informatics fi...

-In today’s world designing adaptable course material requires new technical knowledge which involves a need for a uniform protocol that allows organizing resources with emphasis on quality and Learning. This can be achieved by bundling the resources in a known and prescribed fashion called Learning objects. Learning Objects are composed of two aspects namely “Learning “ and “Object”. The Learn...

The authors introduce the exploration of object-oriented basic concepts as a new approach to object-oriented modelling (OOM). While other subjects have a long tradition in learning by discovery with suitable learning aids (e.g. experimenting installations of the scientific subjects), Informatics at first has to define and to develop such learning aids. Therefore software development environment...

Huge classes with more than 800 students pose a major challenge to lecturers as well as to students, especially when a practical part is included. In order to successfully master lectures of this size, novel kinds of teaching media provide a multitude of enhanced opportunities. In this paper, we present our experiences with the application of new media in our undergraduate course Introduction t...
