The master's thesis deals with the in-memory database SAP HANA which keeps all data directly in main memory with the use of column-oriented data layout. Practical part of the thesis consists in development of application in SAP R/3 environment, with which performance of the in-memory database SAP HANA and the traditional database MaxDB is compared, including influence of used data layout. The results show that the in-memory database is advantageous especially for analytical operations based on aggregate functions.

Expone acerca de una organización dedicada a brindar servicios de trasporte ferroviarios a turistas y públicos. La organización forma parte un grupo de empresas de capitales peruanos Crosland - Inca Rail. La organización actualmente posee un sistema para la planificación de los recursos empresariales (ERP) llamado SAP Bussines Suite, que da soporte a los procesos de finanzas, controlling, logística, ventas y recursos humanos, además cuenta con un sistema legado llamado SAMI (sistema Administrativo Modular Integrado), desarrollado en la tecnología .NET de Microsoft, los cuales interactúan entre sí manualmente, a través de archivos de texto y/o envió de email. La integración actual de las aplicaciones en la organización genera diversos problemas, principalmente retraso en las operaciones debido a la demora en solución de problemas de integración, duplicidad de datos, riesgo alteración de los datos y alto costo de integración de las aplicaciones. El presente informe presenta una propuesta para solucionar este problema que impacta en los procesos operacionales de la empresa, considerando la integración con los otros sistemas de las empresas del grupo y planes de futuras adquisiciones de sistemas. La identificación del problema y los requerimientos de la empresa nos llevó a plantear una solución de integración empresarial, un Bus de Servicios Empresariales (ESB, Enterprise Service Bus). Como alternativas de solución se presenta a dos productos: SAP NetWeaver Process Integration e IBM WebSphere Message Broker para identificar cómo efectivamente uno de ellos puede implementar y soportar una arquitectura orientada a servicios (SOA) y cumplir con la integración empresarial que necesita la organización. Para el producto seleccionado se propone un plan de acción para su propuesta de solución y los criterios de aceptación que deben ser tomados en cuenta para la solución. / Trabajo de suficiencia profesional

Diese Diplomarbeit entstand in Kooperation mit Siemens Power Generation (Kraftwerkebau), EDV-Organisation. Die Arbeit enthält die Konzeption einer Dokumentationsrichtlinie für laufende betriebliche Informationssysteme, vorrangig Systeme der Firma SAP. Umgesetzt wird die Dokumentation mit der Software SAP Solution Manager. Ziel ist die Unterstützung der für die Systeme verantwortlichen Mitarbeiter. Zuerst werden die Grundlagen Dokumentenmanagement und Dokumentation behandelt.

Nach kurzer Beschreibung der zu Grunde liegenden Software SAP Solution Manager wird die Umsetzung des Dokumentationskonzepts in Form der entstandenen Richtlinie beschrieben. Im Anhang befindet sich unter anderem die vollständige Richtlinie, wie sie bei Siemens Power Generation als verbindlich erklärt wurde.

High latitude and altitude ecosystems are currently undergoing rapid and unprecedented warming in response to anthropogenically induced climate change. Subarctic, alpine regions are particularly vulnerable to increases in air temperature and changing precipitation regimes, which have caused cascading hydrological and ecological impacts. In addition to changing flow regimes, thawing permafrost, and declining glaciers, widespread changes in vegetation composition, density and distribution have been observed across northern regions. Specifically, treeline is advancing with increasing latitude and altitude and shrubs are increasing in height, extent, and density. Despite widespread documentation of this northern greening, few field-based studies have evaluated the hydrological implications of these changes. Quantification of total evapotranspiration (ET) across a range of vegetation gradients is essential for predicting water yield, yet challenging in cold alpine catchments due to heterogeneous land cover. Direct field-level measurements of transpiration (T) and evaporative partitioning across subarctic, alpine ecosystems and species are rare, yet essential to assess sensitivities and hydrological response to changing climate drivers. This thesis presents six years of surface energy balance components and ET dynamics and two years of sap flux measurements and critical zone stable water isotope sampling at three sites along an elevational gradient in a subarctic, alpine catchment near Whitehorse, Yukon Territory, Canada. These sites span a gradient of thermal and vegetation regimes, providing a space-for-time comparison for future ecosystem shifts: 1) a low-elevation boreal white spruce forest (~12-20 m), 2) a mid-elevation subalpine taiga comprised of tall, dense willow (Salix) and birch (Betula) shrubs (~1-3 m) and 3) a high-elevation subalpine taiga with short, sparse shrub cover (< 0.75 m) and moss, lichen, and bare rock. We utilize both mass flux measurements and stable water isotopes to evaluate the timing, magnitude, sensitivities, and sources of plant water uptake across these vegetation covers. Total ET decreased and interannual variability increased with elevation, with mean May to September ET totals of 349 (±3) mm at the forest, 249 (±10) mm at the tall, dense shrub site, and 240 (± 26) mm at the short, sparse shrub site. The shrub sites exhibited similar ET losses over 6 years despite differences in shrub height and abundance, although daily rates were higher at the tall shrub site in the peak growing season. From May to September, ET:R ratios were the highest and most variable at the forest (2.19 ± 0.37) and similar at the tall, dense shrub (1.22 ± 0.09) and short, sparse shrub (1.14 ± 0.05) sites. In the mid-growing season, mean T rates were greater at the dense shrub site (2.0 ± 0.75 mm d-1) than the forest (1.47 ± 0.52 mm d-1). During this time, T:ET was lower at the forest (0.48) than at the tall, dense shrub site (0.80). During the growing season between the two years, 2020 was considerably wetter and cooler than 2019. At the tall shrub site, during the mid-growing season (July 1-Aug 15), T dropped considerably in 2020 (-26%), as T was suppressed during the short, wet growing season. In contrast, T at the forest was only moderately suppressed (-3%) between years in this same period. Evapotranspiration was more strongly controlled by air temperature during the early and late season at the forest, while ET at the shrub site was more sensitive to warmer temperatures in the mid-growing season. At the shrub sites, ET was energy limited with no observed soil moisture limitation on T. While 2H and 18O of volume weighted precipitation became more depleted with elevation, the opposite was true in xylem water, where 2H and 18O became more enriched with elevation. Plant water uptake was more reflective of snow water at the forest site than both shrub sites, particularly early in the year and during dry periods. Near-surface bulk soil water had more negative lc-excess at the forest throughout the season and with depth, highlighting increased contributions from soil evaporation. This study combined direct measurements of sap flux, ET, and critical zone isotopes to provide new details on multi-year plant-soil-water dynamics, critical zone water cycling, and species-specific plant water uptake patterns in seasonally frozen soils, which have not previously been reported in cold regions. Our results suggest that advances in treeline will increase overall ET and lower interannual variability; however, the large growing season water deficit and stable water isotope signature at the forest indicates strong reliance on soil moisture from late fall and snowmelt recharge and the potential for plant water stress. Differences between the shrub species were apparent in the sap flux and stable isotope measurements, highlighting the need to further evaluate species specific responses and feedbacks when predicting hydrological fluxes across subarctic ecosystems. Overall, our results suggest that predicted changes in vegetation type and structure in northern regions will have a considerable impact on water partitioning and will vary in a complex way in response to changing precipitation timing, phase and magnitude. / Thesis / Candidate in Philosophy
