About this course

Procura um curso completo, didático e com respaldo das melhores instituições do país? Este curso de PostgreSQL para Análise de Dados foi desenvolvido com base no conteúdo de alto nível ministrado pelo DATA (Grupo de Ciência de Dados do ICMC-USP), unindo o rigor técnico e acadêmico à aplicação prática no mercado de trabalho. Nossa estrutura leva você do nível iniciante às técnicas avançadas de análise relacional:Fundamentos e Consultas Essenciais: Domine a linguagem SQL a partir do absoluto zero com comandos essenciais (SELECT, WHERE, LIMIT, LIKE) e gerenciamento correto de valores nulos (IS NULL / IS NOT NULL).

Estrutura e Manipulação (DDL/DML): Aprenda a criar e gerenciar tabelas (CREATE TABLE), entenda os tipos de dados e garanta a integridade das informações com restrições de negócios (PRIMARY KEY, NOT NULL, UNIQUE). Agregações e Métricas de Negócio: Transforme dados brutos em inteligência com GROUP BY, filtros de grupos (HAVING) e funções agregadoras (SUM, AVG, COUNT, MIN, MAX). Relacionamentos e Subqueries: Conecte tabelas complexas utilizando junções (INNER, LEFT, RIGHT JOIN) e estruture consultas aninhadas dinâmicas.

Higienização e Tratamento de Dados (Data Cleaning): Trate bases reais e inconsistentes aplicando CASE WHEN, COALESCE, NULLIF, conversões de tipos (CAST) e padronização de textos. Agrupamentos Avançados e Modelagem: Organize suas análises com faixas de valores (Binning), reestruturação de tabelas e CTEs (WITH) para criar consultas modulares e altamente legíveis. Análise de Séries Temporais e Funções de Janela: Manipule datas (EXTRACT, DATE_TRUNC), calcule janelas móveis, médias acumuladas e faça comparações temporais período a período (LAG e LEAD).

Análise de Coorte e Retenção: Construa análises comportamentais avançadas para mensurar retenção de clientes, engajamento e ciclos de vida do usuário. Para garantir a fixação real do conteúdo e desenvolver seu raciocínio analítico, após cada aula, você terá acesso a questionários e exercícios práticos projetados para consolidar o aprendizado, testar sua compreensão e desafiar sua capacidade de resolver problemas reais antes de avançar. Você terá total acesso ao material de apoio (slides e apostilas didáticas) para acompanhar o ritmo das aulas, revisar os conceitos e realizar os exercícios práticos nas ferramentas do ecossistema PostgreSQL (como o pgAdmin4).

Garanta sua vaga, aprenda com o padrão de qualidade do DATA - ICMC | USP e leve suas habilidades em SQL e Análise de Dados para o próximo nível!
