    Does e-government contribute to a reduction of farmers’ administrative burden in Switzerland
    (40. GIL-Jahrestagung, Digitalisierung für Mensch, Umwelt und Tier, 2020) Stoinescu, Andrei; Reissig, Linda; Mack, Gabriele
    Since the shift to direct payments and the growing environmental regulations, the administrative costs for farmers and public administration have increased. The introduction of e-government changed the farmers’ working conditions. For this study, we examined how variables such as the ‘perceived organizational benefits’, ‘organizational characteristics’, ‘organizational usage characteristics’ and ‘perceived characteristics’ influence the administrative burden of Swiss farmers when using e-government. A quantitative survey, as well as qualitative open statements and in-depth interviews were analyzed for this purpose. We found that due to the transition from paper to electronic forms, the administrative workload of about one third of the farmers decreased. Attitude and the skills of the farmers seem to influence the administrative burden the strongest.

    Using OPEN.xtrace and Architecture-Level Models to Predict Workload Performance on In-Memory Database Systems
    (Softwaretechnik-Trends Band 39, Heft 4, 2019) Barnert, Maximilian; Streitz, Adrian; Rank, Johannes; Kienegger, Harald; Krcmar, Helmut
    In-Memory Database Systems (IMDB) come into operation on highly dynamic on-premise and cloud environments. Existing approaches use classical modeling notations such as queuing network models (QN) to reflect performance on IMDB. Changes to workload or hardware come along with a recreation of entire models. At the same time, new paradigms for IMDB increase parallelism within database workload, which intensifies the effort to create and parameterize models. To simplify and reduce the effort for researchers and practitioners to model workload performance on IMDB, we propose the use of architecture level performance models and present a model creation process, which transforms database traces of SAP HANA to the Palladio Component Model (PCM). We evaluate our approach based on experiments using analytical workload. We receive prediction errors for response time and throughput below 4 %.

    Vision of Continuously Assuring Performance
    (Softwaretechnik-Trends Band 40, Heft 3, 2020) Reichelt, David Georg; Kühne, Stefan; Hasselbring, Wilhelm
    When assuring performance, small performance differences at code level are difficult to measure at application level. Current approaches aimed at performance assurance are capable of identifying hotspots and major performance bugs. Apart from their inability to detect small regressions, they require manual effort for specification and execution. In this paper, we present the vision of continuously assuring performance by using functional unit tests. Utilizing small tests allows developers to detect small performance differences. Additionally, they do not have to define workloads manually if they use functional unit tests, since these are present in most projects. To achieve this, we propose integrating performance measurements in the continuous integration (CI) process, accelerating root cause analysis and creating parallel tests capable of identifying regressions that arise with parallel use.
