Managing Elixir OTP Persistence with Poncho Projects

When building scalable Elixir applications, organizing your database logic and OTP supervisors cleanly is critical for long-term maintainability. While umbrella projects are common, the poncho project structure offers a powerful, dependency-based alternative for managing application boundaries. This text-based course guides you through the foundational concepts of Elixir design patterns, showing you how to separate your database layer from the rest of your application code. You will learn how to design, configure, and connect database-backed services using Elixir, OTP, Ecto, and PostgreSQL. What you'll learn: - Understand the core differences between umbrella projects and the poncho project structure. - Configure OTP supervisors to manage database connection lifecycles reliably. - Set up Ecto and PostgreSQL integration within a dedicated persistence package. - Implement modern Elixir database queries and schema definitions. - Manage dependencies between isolated local packages using Mix. - Practice structuring application boundaries to ensure clean code separation. You will start with fundamental architectural definitions before stepping through the setup of a multi-package poncho workspace. From there, you will write clear schemas, run migrations, and establish clean communication boundaries between your application layers. This course is designed for beginner-to-intermediate Elixir developers who understand basic syntax and want to learn clean architectural patterns for database design. No advanced OTP experience is required. Start reading today to build cleaner, more maintainable Elixir applications.
