Ecto is a database wrapper and query generator for Elixir. It provides tools for working with databases, managing migrations, and creating schemas to represent your data.

Ecto is a powerful database library in Elixir that serves as a wrapper around databases, providing a convenient interface for interacting with them. It enables developers to perform CRUD (Create, Read, Update, Delete) operations while offering features such as migrations, schema management, and query generation. To start using Ecto, you first add it to your mix.exs file as a dependency. After fetching the dependencies, you can define a repository module that will handle database connections and queries. This repository is responsible for interacting with your database, whether it's PostgreSQL, MySQL, or another supported database. You can then create schemas that represent your data structure, where you define the fields and types that correspond to the database tables. Ecto also includes a powerful query DSL (Domain Specific Language) that allows you to construct complex queries in a readable manner. Migrations in Ecto provide a structured way to modify your database schema over time, enabling version control for your database changes. You can create migration files to add or remove tables, columns, or indices, and run them using Mix tasks. Overall, Ecto is an essential tool for managing data in Elixir applications, making database interactions seamless and efficient.
