The establishment of IT-supported processes within organizations requires the integration of existing distributed legacy applications. Therefore, Web services can be generated as wrappers to flexibly integrate existing distributed legacy applications using a standardized interface. Existing approaches mostly focus on the technical issues of the integration using Web services and do not support the...
A huge amount of schemas are expressed within outdated schema languages which are restricted concerning expressiveness, extensibility, readability, and understandability. Consequently, the actual intention of the schema developers is hard to grasp. Reverse engineering approaches try to tackle this problem by automatically transforming legacy schemas into ontologies, but rarely enhance the semantics...
Geographic knowledge discovery (GKD) is the process of extracting information and knowledge from massive georeferenced databases. Usually the process is accomplished by two different systems, the Geographic Information Systems (GIS) and the data mining engines. However, the development of those systems is a complex task due to it does not follow a systematic, integrated and standard methodology. To...
Integrated systems enable capabilities and performance that independent systems cannot offer. Systems integration, or enterprise application integration, establishes linkages between different computer-based information systems and databases and thus is often required to achieve business integration.There is no conceptual modeling technique designed to help systems integrators elicit, represent, and...
Conceptual models are designed to express user requirements of information systems in a formal and self-explanatory manner from a business user's point of view. Furthermore, they should contain enough information for IT staff to use them as a basis for technical deployment. Within the domain of OLAP information systems, multidimensional data models are used to translate the specific user requirements...
In this experience report we present Business Process Illustration, a technique supporting experience-grounded validation of new business processes by subject matter experts.
The notion of workflows has evolved from a means to describe the flow of paperwork through an organization to a more abstract and general technique used to express best practices and lessons learned in many application domains. When putting workflow definitions into practice, it is important to stay informed which tasks are currently performed, as this allows detecting slipping schedules or unwanted...
The definition of an oracle function for model transformation is challenging because of the very complex nature of models resulting from a transformation. Validating the correctness of an output model requires checking a large number of properties on the structure and semantics of this model. The oracle function can thus be very complex if it checks every property. In this paper, we identify and discuss...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
