Chapter 3Connecting Your Tables to Elixir Structs with Schemas
Functional programs have a set of data structures that form the backbone of the codebase. In the music database we’ve been developing, we’ve got things like artists, albums, tracks, etc. The Ecto.Schema module helps us map those data structures to database tables, so we can seamlessly move data back and forth between our Elixir code and the database. You create the mappings with an elegant, concise DSL, then use associations to connect related structures together.
