Inhalt: O Big Data é uma grande novidade. Mas o que é Big Data e como podemos usá-lo? Simplificando, Big Data são dados que, em virtude de sua velocidade, volume ou variedade (os três vês), não podem ser facilmente armazenados ou analisados usando métodos tradicionais. As planilhas e bancos de dados relacionais não bastam para trabalhar com Big Data. Neste curso, Barton Poulson fala dos métodos que realmente funcionam, apresentando todas as técnicas e conceitos envolvidos na captura, armazenamento, manipulação e análise de Big Data, inclusive mineração de dados e análise preditiva. Ele explica a relação entre Big Data e ciência de dados, estatística e programação; seus usos em marketing, pesquisa científica e ferramentas como o mecanismo de recomendações da Amazon; e as questões éticas subjacentes à sua utilização.
