Design new ecommerce example - donvadicastro/generator-xmi GitHub Wiki

Initially system design should be started with collecting use cases and system requirements. We use Enterprise Architect as design tool and tool to export XMI model for fast prototype generation.

Lets simplify business requirements for e-commerce solution including only next use cases:

After defining all business requirements to the system we need to define boundaries of business context so that domain model need to be defined. We use class model to define domain metadata.

This model includes all entities and relation between entities based on requirements defined. Class model considered to be the data contracts for data transfer and persistence.

After designing data contracts for data transfer and persistence we need to define main system actors and API this actors exposes for data management.

After designing component model we need to design data flow and data processing mechanism between defined component.

As a final stage we need to design user interfaces to interact with system. All entities management pages will be supported out of box.
