A Case study on a service-based information systems integration in academic environment

In corporate environments, we can find various information systems (IS), which need to communicate to each other to share and maintain data consistency. Academic environments (AE) are even more complex than corporate environments because they have several IS to help manage different aspects, such as restaurant and library, which need to have consistent data to work properly. Therefore, it is necessary to encounter a form to develop an integration among them and share common, trustworthy data. We present a case study on SOA-based architecture for IS integration within AE to keep data consistent through the systems, to monitor the communication, and to make the integration safe and manageable. We applied the proposal, and the results show that we can integrate, monitor, and manage different software systems and network services and permissions. The main contribution is a useful integration architecture for AE that must share trustworthy data among several, heterogeneous IS and network systems. In addition, a small team can implement and maintain this proposed architecture

Aligned and collaborative language-driven engineering

Today's software development is increasingly performed with the help of low- and no-code platforms that follow model-driven principles and use domain-specific languages (DSLs). DSLs support the different aspects of the development and the user's mindset by a tailored and intuitive language. By combining specific languages with real-time collaboration, development environments can be provided whose users no longer need to be programmers. This way, domain experts can develop their solution independently without the need for a programmer's translation and the associated semantic gap. However, the development and distribution of collaborative mindset-supporting IDEs (mIDEs) is enormously costly. Besides the basic challenge of language development, a specialized IDE has to be provided, which should work equally well on all common platforms and individual heterogeneous system setups. This dissertation describes the conception and realization of the web-based, unified environment CINCO Cloud, in which DSLs can be collaboratively developed, used, transformed and executed. By providing full support at all steps, the philosophy of language-driven engineering is enabled and realized for the first time. As a foundation for the unified environment, the infrastructure of cloud development IDEs is analyzed and extended so that new languages can be distributed on-the-fly. Subsequently, concepts for language specialization, refinement and concretization are developed and described to realize the language-driven engineering approach, in a dynamic cluster-based environments. In addition, synchronization mechanisms and authorization structures are designed to enable collaboration between the users of the environment. Finally, the central aligned processes within the CINCO Cloud for developing, using, transforming and executing a DSL are illustrated to clarify how the dynamic system behaves

A Metadata-Driven Approach to Panel Data Management and its Application in DDI on Rails

This dissertation designs a metadata-driven infrastructure for panel data that aims to increase both the quality and the usability of the resulting research data. Data quality determines whether the data appropriately represent a particular aspect of our reality. Usability originates notably from a conceivable documentation, accessibility of the data, and interoperability with tools and other data sources. In a metadata-driven infrastructure, metadata are prepared before the digital objects and process steps that they describe. This enables data providers to utilize metadata for many purposes, including process control and data validation. Furthermore, a metadata-driven design reduces the overall costs of data production and facilitates the reuse of both data and metadata. The main use case is the German Socio-Economic Panel (SOEP), but the results claim to be re-usable for other panel studies. The introduction of the Generic Longitudinal Business Process Model (GLBPM) and a general discussion of digital objects managed by panel studies provide a generic framework for the development of a metadata-driven infrastructure for panel studies. A first theoretical application presents two designs for variable linkage to support record linkage and statistical matching with structured metadata: concepts for omnidirectional relations and process models for unidirectional relations. Furthermore, a reference architecture for a metadata-driven infrastructure is designed and implemented. This provides a proof of concept for the previous discussion and an environment for the development of DDI on Rails. DDI on Rails is a data portal, optimized for the documentation and dissemination of panel data. The design considers the process model of the GLBPM, the generic discussion of digital objects, the design of a metadata-driven infrastructure, and the proposed solutions for variable linkage
