Ecto is commonly used to interact with databases, such as PostgreSQL and MySQL via Ecto.Adapters.SQL (source code). Ecto is also commonly used to map data from any source into Elixir structs, whether they are backed by a database or not.

See the getting started guide and the online documentation for more information. Other resources available are:

• Programming Ecto, by Darin Wilson and Eric Meadows-Jönsson, which guides you from fundamentals up to advanced concepts

• The Little Ecto Cookbook, a free ebook by Dashbit, which is a curation of the existing Ecto guides with some extra contents
