Al tratar de ingresar al movimiento NoSQL, existen diversas formas de modelar la información, lo que lo convierte en un proceso lento y, al elegir entre diversas tecnologías para administrar los datos, puede llegar a ser improductivo sino se tienen claras las características requeridas para el manejo de la información. En esta investigación se implementan seis modelos dentro del ambiente NoSQL (Orientado a documentos, orientado a columnas, clave­valor, grafos, orientado a objetos y multimodelo), y se evalúa el desempeño al abordar un desafío común: el modelado y administración de datos jerárquicos. A través de la comparación se exponen las ventajas y limitaciones de las seis tecnologías seleccionadas y del modelado que representan.
