Learn web development with Elixir. We use GenServer Behaviour for a stateful backend. The front-end will use Phoenix Channels to communicate with the backend.

Elixir and OTP provide exceptional tools to build rock-solid backend applications that scale. In this course, you’ll build a web application in a radically different way, with a backend that holds application state. You’ll use persistent Phoenix Channel connections instead of HTTP’s request-response, and create the full application in distinct, decoupled layers.

In Part 1, you’ll start by building the business logic as a separate application, without Phoenix. You’ll model the application domain with Elixir functions and simple data structures.

In Part 2, you’ll add in the GenServer Behaviour to make managing in-memory state a breeze. 

In Part 3, you’ll build a web interface with Phoenix where you’ll use Phoenix Channels to establish persistent connections between the stateful server and a stateful front-end client.

Needless to say, you’re going to love this way of building web apps!

## CRUD operations
We need to create a new table with the Erlang `:ets.new/2` function to start using ETS. The `:ets.new/2` function takes an atom for the name of the table we’re creating and also takes a list of options. Once we have a new table, we’ll see how the **CRUD** operations work: creating, retrieving, updating, and deleting records.

## Try it out
Let’s try this out with a test example.
