Ubiquitous Language (Glossary)

For definitions of various terms, refer to edX DDD Ubiquitous Language.

edX Subdomains

Illustrates a high-level view of the main subdomains within the edX system.

edX Subdomain Map

Illustrates interactions between the high-level subdomains of the edX system. This was generated from captured top-level edX Use Cases and aligning on the main responsibilities of each subdomain in the edX life cycle.

edX Bounded Contexts

Illustrates possible bounded contexts within each subdomain. It shows where today's shared data storage is located. The responsibility of each bounded context is described below.

Responsibilities of Bounded Contexts

This section describes the responsibilities of each bounded context as depicted in the diagram above.
