Abstract: The web app QDAcity supports the process of qualitative data analysis (QDA). Among other things QDAcity can aid users during the coding process. A unique feature of QDAcity is that the user can classify codes of their code system using a meta model. The meta model helps in structuring the...

Abstract: Many modern software applications and research projects depend on the ability to access high-qualitative data sources. Even though there is already a large number of openly available data sets, such data sets are often hard to (re)use due to various barriers such as incomplete documentati...

Abstract: Open data has been known for having data quality issues that require complex data cleansing and data transformation in order to be usable for data analysis, data visualization, training machine learning algorithms, and other data science activities. Open Data Service (ODS) is a software p...

Abstract: Collaborative software allows people to work together to achieve a common goal. However, users might be distracted from their goals when such an application evolves with more functionalities. Moreover, when multiple users collaborate in the same session, the action of one user might confu...

Abstract: In qualitative research, Intercoder Agreement (ICA) represents the extent to which two or more researchers share the interpretation of the data. The ICA assessment adds investigator triangulation to a project and helps researchers validate their findings. QDAcity is a cloud-based applicat...

Abstract: Nowadays the internet provides a lot of open data for public use. Those can be written in various data types and cover plenty of subjects. Because of that the absence of a standard results into the main problem. Every provider can decide for himself how the data is constructed. The JValue...

Abstract: The JValue project group is developing a modeling ecosystem for Extract Transform Load (ETL) processes. Part of this ecosystem is a description model for those. This thesis suggests a conversion process from the description model into an Apache Kafka runtime, described in a cloud-native f...

Abstract: Software Elasticity is the concept of adapting available resources to the current or expected workload. This concept fits modern and stateless microservice architectures, which are scalable by design. Their scalability is closely related to Software Resilience and places new demands on cl...

Abstract: Microservice-Systeme bestehen aus eigenständigen, verteilten Services, die über Netzwerkverbindungen miteinander kommunizieren. Das Testen von Service-Integrationen kann bei derartigen Systemen eine Herausforderung darstellen, da hierzu mehrere Services zur selben Zeit ausgeführt werden m...

Abstract: 'Microservices' sind in der heutigen Zeit ein bekanntes und beliebtes Architekturmuster. Viele weltbekannte Tech-Unternehmen haben sich für diese entschieden. Die Entkopplung und die Aufteilung der Aufgaben in kleinere Services bringen neben daraus resultierenden Vorteilen auch Herausford...
