Bancos de dados e SQL para Ciência de Dados from Coursera

Grande parte dos dados do mundo reside em bancos de dados. SQL (ou Structured Query Language) é uma linguagem poderosa usada para se comunicar e extrair dados de bancos de dados. Um conhecimento prático de bancos de dados e SQL é essencial se você deseja se tornar um cientista de dados. O objetivo deste curso é apresentar os conceitos de banco de dados relacional e ajudá-lo a aprender e aplicar o conhecimento básico da linguagem SQL. Também se destina a ajudá-lo a começar a executar o acesso SQL em um ambiente de ciência de dados. A ênfase neste curso está no aprendizado prático e participativo. Como tal, você trabalhará com bancos de dados reais, ferramentas de ciência de dados reais e conjuntos de dados do mundo real. Você criará uma instância de banco de dados na nuvem. Por meio de uma série de laboratórios práticos, você praticará a construção e a execução de consultas SQL. Você também aprenderá como acessar bancos de dados do notebook Jupyter usando SQL e Python. Não é necessário conhecimento prévio de bancos de dados, SQL, Python ou programação. Qualquer pessoa pode assistir a este curso gratuitamente. Se você optar por fazer este curso e obter o certificado do Coursera, também poderá obter um selo digital da IBM após a conclusão do curso.
