Existe un prejuicio que indica que las bases de datos NOSQL, no son competentes frente a las SQL, asociado al poco interés o poca información de los profesionales de TI sobre las bondades de las bases de datos orientadas al modelo NOSQL, y, porque no, el creer que las bases de datos NOSQL, se encuentran en una fase de inicio, esto genera la duda que produce está investigación. El proyecto de investigación busca hacer una comparación, entre las bases de datos SQL y las bases de datos NOSQL. Esta investigación empieza señalando un preámbulo de las bases de datos SQL, además de hacer un diagnóstico individual del modelo de base de datos relacional y no relacional, y así reflejar una serie de comparaciones entre ambos modelos que involucre varios criterios de evaluación entre dichos modelos. La contribución consiste en un análisis comparativo de modelos de datos, que nos permi...

Stevia rebaudiana is considered an important medicinal plant possessing low-calorie glucoside sweeteners. The present work describes the comparison of three stevia genotypes (IBT 1, IBT 2 and IBT 3) in two contrasting environments simulated under controlled conditions: Sullana in Peru; and Misiones in Paraguay (regarded as the center of origin of Stevia). In the study, we explored the Euclidean distance as an integrating indicator for simultaneous selection of several stevia traits. Plant scientists often record multiple morphological, physiological and biochemical indicators in their experiments. Common statistical data evaluations involve univariate analyses such as t-test, Mann-Whitney and Analysis of Variance followed by Tukey HSD. However, these analyses do not evaluate integrally the effects of the experimental treatments because each indicator is analyzed independently. Euclidean ...
