The number of scientific publications has increased exponentially in the last decades. To better compare these ever-increasing results and to help further replication studies, the use of open data has been suggested. But how should empirical data be described? This paper presents a meta-model for empirical findings that is conceptually linked with the formal description of causal theories. Based on...
We outline a methodology for automatic and efficient object-relational mapping (ORM) in the context of model-driven development (MDD) of high-performance information systems specified with executable UML models. Although there are various approaches to performance tuning, we focus here on the persistence layer the relational database. The relational data model is usually designed following the well-known...
The use of spreadsheets to implement Information Systems is widespread in industry. Scripting languages and ad-hoc frameworks (e.g., Visual Basic for Applications) for Rapid Application Development are often exploited by organizations to quickly develop Spreadsheets-based Information Systems for supporting the information management of their business processes. Maintenance tasks on these systems can...
The potential impact of model-driven engineering is considerable, and far extends beyond the initial development and delivery of a system. The automatic generation of systems from abstract models also facilitates evolution: the definitive description of structure and behaviour remains accessible, and changes are more easily planned and accommodated. Within the domain of information systems, this is...
A decision information system (DIS) is a specific component of information system specialized in the support of decision-making by means of online analytical processing tools. Data warehouses (DW), at the core of DIS, integrate and historize collections of data often designed starting from the operational components of the Information Systems (IS). Methods, techniques and tools widely used in the...
Models of different kinds are used in the area of business process management. Abstract process knowledge as well as executable process definitions can be visualized and edited in a graphical manner. The same holds true for models of process instances in some process-aware information systems (PAIS), which allow for dynamic modifications in a process instance during process runtime. An appropriate...
