ETL processes play an increasingly important role for the support of modern business operations. These business processes are centred around artifacts with high variability and diverse lifecycles, which correspond to key business entities. The apparent complexity of these activities has been examined through the prism of Business Process Management, mainly focusing on functional requirements an...

This report discusses application design for active databases, in particular for the active object-based database programming language Degas. In Degas one modularisation principle, the object, is applied to all elements of the application, including rules. We discuss a design process consisting of four phases, corresponding with the four kinds of capabilities in a Degas object, attributes, meth...

Nowadays, traditional testing approaches become less feasible – both economically and practicably for several reasons, such as an increasingly dynamic environment, shorter product lifecycles, cost pressure, as well as a fast growing and increasingly segmented hardware market. With the surge towards new modes of value creation, crowdsourced software testing (CST) seems to be a promising solution...

Artifact-centric process modelling is a promising technology to manage business operations. The Guard-Stage-Milestone (GSM) life-cycle is a declarative approach to specify artifacts and their lifecycles. Currently there’s no approach to manage process variability in the field of artifact-centric business process models. Existing variability management approaches are designed especially for acti...

The SEVIRI instrument on the Meteosat Second Generation satellite with both fine spatial and temporal resolution allows to detect and follow the dynamics of fast developing meteorological events like spreading smoke plumes and the lifecycles of convective clouds. Smoke plumes have the ability to change the atmospheric heat content due to 5 absorption and reduced reflection of solar radiation. B...

Artifact-centric business process models have gained increasing momentum recently due to their ability to combine structural (i.e., data related) with dynamical (i.e., process related) aspects. In particular, two main lines of research have been pursued so far: one tailored to business artifact modeling languages and methodologies, the other focused on the foundations for their formal verificat...

Evolving e-commerce technologies increasingly enable organisations to participate in different types of network forms or in electronic markets with previously unidentified trading partners. Virtual organisations (VO) take different forms, have varying lifecycles and involve different scope and depth of relationships. This paper examines the literature in terms of the terminology of virtual orga...

In “How to simplify the evolution of business process lifecycles,” Alexander Samarin writes, “To achieve high flexibility in the business we want processes, services and other artifacts to be distinct and versionable, whereby each artifact can be evolved easily. We need to consider a business as a complex dynamic mixture of processes, services and other artifacts. The composition and the struct...

IT environments are a continuously changing entirety. Software and systems in these environments go through their lifecycles and then they are replaced with more advanced and economical solutions. This is a normal phenomenon in education and corporate life. The study examines if and how the different systems could be replaced with a single version control system (VCS) and how to prepare and exe...
