  • Web Applications
  • Mobile Applications
  • Data Logging Applications

Even though it is relational database and best suited for transactional systems (OLTP), it’s flavors such as Redshift are extensively used for Analytical or Decision Support Systems.

Course Details

This course is primarily designed to go through basic and advanced SQL using Postgres Database. You will be learning following aspects of SQL as well as Postgres Database.

  • Setup Postgres Database using Docker
  • Connect to Postgres using different interfaces such as psql, SQL Workbench, Jupyter with SQL magic etc.
  • Understand utilities to load the data
  • Performing CRUD or DML Operations
  • Writing basic SQL Queries such as filtering, joins, aggregations, sorting etc
  • Creating tables, constraints and indexes
  • Different partitioning strategies while creating tables
  • Using pre-defined functions provided by Postgresql
