Understanding, processing and utilising relevant data from a wide range of sources has become a central component of digital transformation in both the public and private sector. In this context, gaining insight and developing methodologies towards establishing data-driven services contributes to so-called “data sovereignty”. However, such potentials are far less exploited for municipal and regional authorities than for national and federal administrations or private businesses and industry.

Biologists at Oldenburg University's Botanical Garden are researching ways of cultivating potted plants while conserving resources. Among other things, they cover soil of potted plants with microclover to protect water in the soil from evaporation. Water consumption during the cultivation of potted plants is thus reduced. In order to confirm or disprove the positive water saving effect of microclover soil cover, it is necessary to evaluate effects of this type of soil cover. As it turns out, the evaluation is a great challenge that the Botanical Garden's Biologists, the Software Engineering Department and the Systems Software and Distributed Systems Department are facing with an adaption of the environmental information system Guerilla Sensing.

Agile frameworks are a well-established methodology for software development and other activities. But the Agile Manifesto and frameworks like Scrum leave many tasks and options open for interpretation and implementation. For example, Scrum starts with a filled product backlog, but does not include a process for requirements engineering. The Agile Frameworks project deals with questions and open steps like this.

IoT is a multi-aspect domain that encompass heterogeneous technology stack applying hardware, software and network. Moreover, IoT development activities require the participation of various stakeholders that provide expertise in different domains and they have different concerns regarding the system. These concerns may cover different aspects of the IoT system, such as system requirements, interoperability between hardware and software, network aspects, etc. To effectively conduct development activities, stakeholders need a common infrastructure, where they can address their concerns regarding the system from their own viewpoint. Concerns may cover various aspects like requirements, “thing” components, services, etc. As stakeholders work on different aspects of the IoT system, there is a need to ensure the consistency of the elements within the system. Therefore, viewpoints need to be integrated to allow keeping elements synchronized in different views.

This project addresses challenges of describing IoT aspects in the form of viewpoints and integration of viewpoints.

This research area includes the development of process models for software development and software evolution, and the adaption of existing process models for specific needs of companies.

In der Programmier- und Softwaretechnikausbildung ist neben der Vermittlung theoretischer Grundlagen ein wichtiger Aspekt die praktische Anwendung und Umsetzung der gelernten Konzepte durch die Studierenden. Dabei geht es um Programmierung und Modellierung von einfachen bis zu komplexen Aufgaben als Aspekte der Softwareentwicklung. Primärziel des Projektes ist es, den Studierenden eine Plattform zum Selbststudium bereitzustellen, auf der sie zeitnah Rückmeldungen zu Fehlern und Problemen ihrer Programmier- und Modellierungslösungen erhalten, die aber gleichzeitig durch Automatisierung für bis zu 500 Studierende einer Veranstaltung skaliert. Die Plattform soll sowohl für Einzelarbeit als auch für Team-basierte Entwicklungsmethoden wie Pair-Programming oder kollaborative Modellierung ausgelegt sein.

Cyber-Physical Systems (CPS) represent one of the most prominent trends in computer technology, creating a deep integration of hardware and software components. They have evolved in conjunction with Internet of Things (IoT) and various smart approaches, in manufacturing, transportation, health care, buildings, emergency response. As the world has become increasingly inter-related - due to services, mobile devices, Cloud Computing, and wireless networks - CPS have highly proliferated, facing challenges like scalability, composability, and heterogeneity. The aim is to elaborate integrated models that drive cyber-physical systems, and specific modeling languages, for dealing with the level of complexity required in real-world settings.

Recent technological advancements have led to an increasingly interconnected world, leading to new, autonomous smart devices and services that permeate everyday life (Internet of Things) and industry (Industry 4.0). This opens up a wide array of opportunities for applications in diverse domains. At the same time, the systems supporting these applications are reaching new levels of complexity, necessitating appropriate engineering methodologies. Model-driven Engineering provides the required foundations for formally rigorous development of software-intensive systems, but is still a long way from realizing its full potential, and the adoption in industry remains limited.

The Smart Modeling project is aimed at providing a thematic framework to facilitate knowledge exchange between computing science research groups at the University of Oldenburg, Germany, and the Tashkent University of Information Technologies in Uzbekistan, as well as industry partners. The project’s workshops act as student and doctoral symposium to promote young researchers, and as discussion forum to identify research and collaboration opportunities based on scientific challenges and concrete industry needs. Major outcomes will be a comprehensive report on the state of the art of model-driven engineering, jointly developed by participating young researchers, and concrete proposals for follow-up collaborative projects to advance Smart Modeling research, improve its coverage in education, and transfer results into practical application.

In this cooperation project, TARGIS GmbH and the University of Oldenburg examine approaches to software development and maintenance, including tool support. These approaches are targeted to the concrete requirements of the TARGIS GmbH, and are tested and refined in an application environment.

Programming is one of the fundamental skills any aspiring computer scientist must possess. To assist students in their endeavor, the Carl von Ossietzky Universität Oldenburg provides several courses on different levels that cover the relevant topics in the field of programming. Goal of the “Harmonisation of the Training in Programming” (HTP) project is to optimize the existing set of courses, to identify and eliminate overlap, to leverage synergies, to incorporate new findings from didactic research, and to re-organize where necessary.

With more than 60% of the german population living in rural areas, where public transport coverage is, in general, declining, diverse mobility needs arise. NEMo is an interdisciplinary, holistic approach towards fulfilling those needs by considering social, demographic, accessibility, legal, economic, and ecological conditions and objectives. IT is seen as key enabler to create a mobility platform software system for the provision and consumation of mobility services.

The software engineering group seeks to research, develop, and apply novel means to bridge the semantic gap between business processes and component-based implementations. The group's Sensei approach, originally conceived as service-oriented, model-driven framework for tool integration, provides the basis, and will be extended and generalized to meet the demands of the NEMo project in particular, and software development beyond tool integration, in general.

Software Testing in Cloud Computing

In multi-perspective software development, several perspectives exist presenting different views on the developed artefacts. Because some perspectives handle the same data and all the data have relationships between each other, there is a strong need for synchronization of the data between different perspectives. To solve this problem, this project aims at developing and validating a method for integrating the single metamodels of each perspective into one integrated single underlying metamodel (SUMM).
