Database Integration in Elixir with Ecto Repo

Integrating a reliable database layer is a critical step in building robust Elixir applications. Understanding how Ecto manages connections and queries ensures your application data remains consistent, secure, and highly performant. This text-based course guides you through the foundational concepts of Ecto, Elixir's database wrapper and query generator. You will progress from understanding core database configurations to writing safe, efficient queries and managing complex data transformations. What you'll learn: Understand the core architecture of Ecto and how the Repo module interacts with your database; Configure and establish secure database connections within a standard Elixir application; Write safe database queries using the Ecto Query API to prevent common security vulnerabilities; Perform standard CRUD operations efficiently to create, read, update, and delete database records; Apply Ecto changesets to validate and cast external data before saving it; Manage database state transitions safely using modern migration patterns. The course starts with essential database terminology and setup, moving systematically through schemas, changesets, and repository operations. You will read clear explanations and analyze structured code snippets to build confidence in your database design choices. This course is designed for beginner Elixir developers looking to connect their applications to a database, with no prior Ecto experience required.
