RxJS is one of those technologies we use every day in our Angular projects, but there is always a bit more to learn:

In the first half of the session we'll see how:
- RxJS subject objects can be used to create Observable Services and even simplify state management by using an Observable Store.

In the other half of the session, we see how we can get around without "subscribing" to an Observable to:
- Collect data from a backend server using a declarative approach.
- Compose data streams to handle foreign key and aggregate relationships.
- Cache these streams in a service so they can be readily reused.
