Abstract: QDAcity is a cloud-based web application for multiple researchers to collaboratively conduct Qualitative Data Analysis (QDA) in shared projects. Qualitative data (in textual, visual, or audio form) can be open for interpretation and drawing of subjective conclusions. Thus, enabling and en...

Abstract: Nowadays, many applications are developed using a microservice-based architecture. In this context, a software product consists of many individually developed services that communicate over a network. As microservices do not necessarily share a common code base, syntactic interoperability...

Abstract: Continuous improvement of products and processes is one of the key goals of any software development team striving for success in its company. As we know from the practice, necessary improvements are not only hard to identify but sometimes it is even harder to integrate them into a workin...

Abstract: Software engineering productivity is a metric that can be an indicator for software quality, development efficiency and developer satisfaction. As a result, the metric can be used for managerial decision making and is crucial to the success of a software project. However, even though the ...

Abstract: Microservice-based systems consist of loosely coupled, independent distributedservices, communicating over the network. The integration of the frontend in microservices is a central problem. In contrast to the back end services, one independent service is often used for the front end of a...

Abstract: Qualitative Data Analysis (QDA) is a tedious and time-consuming process that can be supported by the Computer-Aided Qualitative Data Analysis Software (CAQDAS) QDAcity. To prepare the software for commercial release, this thesis tests hypotheses about the interest and added value of the s...

Abstract: Open Source represents a non-hierarchical and collective approach to software development, that has seen unprecedented success and rapid adoption across a multitude of fields. Inner Source is an attempt to siphon some of the advantages of the Open Source paradigm by applying it to interna...

Abstract: Web applications can have a high level of functionality and complexity, making them difficult for users to use intuitively. Users can then resort to instructions or tutorials in order to learn how to use the application correctly. Tutorials that not only impart knowledge but also explain ...

Abstract: The JValue Open Data Service (ODS) is an ETL data pipeline that provides data extraction from different source systems (Extract), performs transformations on the extracted data (Transform), and loads the data to a target database (Load). There are different kinds of stream processing engi...

Abstract: With modern applications growing in complexity, an increasing reliance on third party components can be observed across the industry. Such reuse of Free/Libre Open Source Software (FLOSS) or Commercial off-the-shelf (COTS) artifacts can help reduce time to market and enable faster release...
