Última Comparación de una consulta típica de análisis de negocios usando dos estructuras diferentes de bases de datos. Colegio de Postgraduados González Espinosa, Juan. El crecimiento tanto de los tamaños de los almacenes de datos como de su utilización por empresas y organismos para analizar la información ha dado lugar al desarrollo de diversas tecnologías que se plantean como alternativas a las bases de datos relacionales para estructurar y almacenar los datos: Esto se debe a que éstas no proporcionan tiempos de respuesta adecuados en consultas no planeadas o predecibles como las que se presentan en el análisis de negocios o la minería de datos. Las bases relacionales se crearon para el proceso de transacciones, donde se incluyen en el modelo índices para los usos planeados de los datos. La ausencia de ciertos índices puede resultar en la lectura de toda una o varias tablas (table scans), lo que impacta en los tiempos...

Ano: 2011 URL: http://hdl.handle.net/10521/385 The Marketing Performance of Illinois and Kansas Wheat Farmers AgEcon Dietz, Sarah N.; Aulerich, Nicole M.; Irwin, Scott H.; Good, Darrel L.. The purpose of this paper is to investigate the marketing performance of wheat farmers in Illinois and Kansas over 1982-2004. The results show that farmer benchmark prices for wheat in Illinois and Kansas fall in the middle-third of the price range about half to three-quarters of the time. Consistent with previous studies, this refutes the contention that Illinois and Kansas wheat farmers routinely market the bulk of their wheat crop in the bottom portion of the price range. Tests of the average difference between farmer and market benchmark prices are sensitive to the market benchmark considered. Marketing performance of wheat farmers in Illinois and Kansas is about equal to the market if 24- or 20-month market benchmarks are used, is slightly above the...

Ano: 2009 URL: http://purl.umn.edu/48762 Stata and the WeeW information system AgEcon Vittorini, Pierpaolo; Necozione, Stefano; di Orio, Ferdinando. The need for timely collection and analysis of epidemiological data is becoming of primary importance, e.g., for bioterrorism detection or epidemiological surveillance. Web-based information systems (WISs) may provide the needed technological support. Thus we present the WeeW (workflow-enabled epidemiological WIS) system—i.e., a WIS that helps epidemiologists, through workflow management, to effectively select remote centers, collect, and process the received data to produce conclusive technical reports. In detail, we show the functionalities of the WeeW system, its architecture, and particularly Stata’s role in executing statistical analyses and producing graphs. Furthermore, we discuss the performance of the WeeW–Stata interface. Finally, we outline...
