The application business

Our application is responsible for providing the quote prices to HTTP or WebSocket clients. With its model and customer/quote relationship, it can enable us to provide (or not provide) the price accessed by the customer if we add permissions or rules, for instance. What is important to see at this stage is that both the entities are in a relationship and that our application can visit this relationship for its business needs and trigger an implicit lazy loading of the relationship entities.

The data is injected into the system based on two external HTTP sources (CBOE and Yahoo). The first one provides a symbol dictionary of the quotes, and the second one, the prices.
