Experience

eva's platform is based on a microservices architecture and every component has its Rest APIs. A basic understanding of this architecture helps understand the APIs and the content on the next chapters.

The Broker is the orchestrator of the solution. It is responsible for receiving the information needed to execute a conversation. Its API is the one called when a channel receives a message from the user.

Also, it is responsible for calling NLPs dynamically, depending on which NLP was selected by the user in the Cockpit, and for calling external services when these are registered in the Cockpit through the webhook fields.

The main database, which is used by the Broker, is a MySQL database that contains all configuration made through the Cockpit as well as data generated through conversations by the Broker.

Another important component is the Dialog Manager, where you can build and manage the virtual agent conversation flows. This module has its own NoSQL database, for a better performance of the virtual agent. All conversation flows created in the Cockpit are stored in this MongoDB.

The extraction details explained in the following chapters will detail only the MySQL database, since it contains the conversation logs.
