Problem Domain Analysis and Development Process in MDDPlatform: An Online Ordering System Example

This document is supplementary material accompanying the paper titled "Microservice-based model-driven architecture for implementing modeling and model-transformation as a service". This document presents complementary materials that describe the end-to-end model-driven development process within MDDPlatform. It begins with a problem domain analysis using the CRAC metamodel, addressing order, customer, product, and shopping cart subdomains. It then details the proposed model-driven development and code generation processes, followed by a demonstration of the approach through an online ordering system example. Together, these sections illustrate how problem analysis and process design are systematically operationalized into a real-world software solution.
