Database Persistence with Ecto Migrations in Elixir

Building scalable, fault-tolerant applications in Elixir often requires a robust way to persist data. To achieve this, developers rely on Ecto, a powerful database wrapper and query generator. This text-based course guides you through the foundational concepts of database integration in Elixir, taking you from raw database concepts to confidently writing Ecto migrations, defining database schemas, and persisting data for OTP-based applications. What you'll learn: - Understand core Ecto architecture, including repositories, schemas, and migrations. - Configure an Elixir application to connect securely to a PostgreSQL database. - Create and run Ecto migrations to build and alter structured database tables. - Define Ecto schemas to map database records to native Elixir structs. - Apply data validation rules using changesets to ensure database integrity. - Implement database indexes and constraints to optimize performance and safety. The course starts with essential database terminology and configuration before walking you through the syntax of writing clean, modern Ecto migrations. Through detailed written explanations and practical code snippets, you will learn how to transition schemas, run migrations, and verify your database state. Designed for beginner Elixir developers, this course requires no prior experience with Ecto or PostgreSQL. Start reading today to master database migrations and build resilient Elixir applications.
