Tutorial 1: Your First Architecture Model

In this tutorial, you will create a simple model linking a customer actor to a web application and database.

1. Create model.ea

workspace simple_app "Simple Web Application" {
    actor user_shopper "Online Shopper" {
        role "Customer"
        is_external true
    }

    app web_store "Web Storefront" {
        technology "Next.js / Node.js"
        internet_facing true

        relationships {
            this serves user_shopper "Provides product catalog and checkout"
            this writes data_orders "Persists customer orders"
        }
    }

    data_object data_orders "Order Records" {
        classification "Confidential"
    }
}
