E-commerce Package Diagram

E-commerce package diagram

An e-commerce package diagram gives a high-level view of how an application is organized. Packages represent coherent areas such as the storefront, catalog, checkout, orders and payments. Dependency arrows show which package needs services or data from another one. This level of detail is useful in an architecture review because it exposes coupling without filling the page with every class. Add or remove representative classes as the system boundaries become clearer, but keep the diagram focused on package responsibilities.

자주 묻는 질문

What belongs in a package diagram?

Major modules, namespaces or layers and the dependencies between them.

Why use representative classes?

They make the responsibility of a package clear without turning the diagram into a full class model.

What does a dashed arrow mean?

It indicates a dependency: one package uses or relies on another.
