Syllabus

WEEK 1
Introdução a bancos de dados e SQL básico
Na semana 1, você será apresentado aos bancos de dados. Você criará uma instância de banco de dados na nuvem. Você aprenderá algumas das instruções SQL básicas. Você também escreverá e praticará SQL básico em um banco de dados ativo.

WEEK 2
SQL avançado
Ao final deste módulo, você aprenderá o seguinte: (1) Aprenderá a usar padrões e intervalos de string para pesquisar dados e como classificar e agrupar dados em conjuntos de resultados. (2) Aprenderá a trabalhar com várias tabelas em um banco de dados relacional usando operações de junção.

WEEK 3
Como acessar bancos de dados usando Python
Depois de concluir as lições desta semana, você aprenderá como explicar os conceitos básicos relacionados ao uso de Python para se conectar a bancos de dados e, em seguida, criar tabelas, carregar dados, consultar dados usando SQL e analisar dados usando Python

WEEK 4
Tarefa do curso
Como uma tarefa prática de Ciência de Dados, você trabalhará com vários conjuntos de dados do mundo real para a cidade de Chicago. Serão feitas perguntas que o ajudarão a entender os dados da mesma forma que um cientista de dados faria. Você será avaliado quanto à exatidão de suas consultas SQL e resultados.
