by
Jan 23, 2018

Google, Bing, Yahoo y otros motores de búsqueda dependen de raspadores web y bots para tirar contenido de internet. También usan diferentes arañas y rastreadores web para indexar páginas web; un extractor de bases de datos, también conocido como extractor de datos, le permite raspar información útil de la World Wide Web. Funciona completamente en segundo plano y responde a las consultas. Además, puede transformar los datos sin procesar y sin organizar en estructurados, organizados, legibles y escalables.

Con un extractor de base de datos, puede analizar fácilmente páginas web, extraer correos electrónicos, números de teléfono y fax, y guardar el contenido en su disco duro para la exploración sin conexión. Esta herramienta utiliza patrones reconocibles para identificar los campos de datos y los extrae de acuerdo con sus requisitos. Los mejores extractores de datos se discuten a continuación.

 1. PRTG Data Extractor: 

PRTG Data Extractor es un extractor de bases de datos interactivo y potente que se utiliza principalmente para recopilar datos brutos de la base de datos interna de un servidor PRTG.

También puede controlar la calidad de sus datos y usarlos en combinación con otros extractores de datos. Este servicio le permite evaluar los informes de datos de manera única e interactiva, lo que le permite ahorrar tiempo y energía en cierta medida.

Con DB Dumper, puede descargar archivos ZIP en su disco duro con solo una pocos clics y no necesita comprometer la calidad de su contenido web. Se utiliza principalmente para extraer información de gráficos y tablas y utiliza un controlador ODBC para conectarse y trabajar con bases de datos. Tiene varias opciones y características únicas para facilitar las tareas de análisis de datos y puede ayudarlo a extraer etiquetas de Internet, metadescripciones, palabras clave, descripciones de productos e información sobre precios. Los datos raspados se pueden exportar a archivos TSV, personalizados, HTML y CSV sin ningún problema. Este servicio puede analizar de cientos a miles de archivos en pocos segundos y recopilar contenido informativo para usted.

 3. Extractor de base de datos SQL: 

Una de las características más distintivas y destacadas de SQL Database Extractor es que puede eliminar información de una gran cantidad de archivos y guardar en un formato predefinido. También puede orientar metaetiquetas y descripciones de productos con este servicio, y los datos se recopilan de la base de datos interna sin ningún problema.

 Crawlbot - Una alternativa a los Web Extractors antes mencionados: 

Varios empresarios y programadores optan por Diffbot debido a sus propiedades interactivas, confiables y únicas. Sin duda, Crawlbot es uno de los mejores web scrapers en Internet que ofrece una solución inteligente para páginas web dinámicas.
