Ecto
Ecto is split into 4 main components:
-
Ecto.Repo- repositories are wrappers around the data store. Via the repository, we can create, update, destroy and query existing entries. A repository needs an adapter and credentials to communicate to the database -
Ecto.Schema- schemas are used to map any data source into an Elixir struct. We will often use them to map tables into Elixir data but that’s one of their use cases and not a requirement for using Ecto -
Ecto.Changeset- changesets provide a way for developers to filter and cast external parameters, as well as a mechanism to track and validate changes before they are applied to your data
