TL;DR

This paper presents WebShop, a UML-based e-commerce framework designed to demonstrate the application of UML and UML-F in web application development. It focuses on modeling key variation points in online catalogs without implementing full security or production-ready features, serving as an educational and illustrative reference for software engineering practices in e-commerce systems.

ABSTRACT

This paper presents an e-commerce framework called WebShop, which was developed by the authors for the purpose of demonstrating the use of UML and the UML-F in the domain of Web applications. Thus, the WebShop is not regarded as a full-fledged system out of which real Web stores can be derived. For example, the framework in the presented version does not encounter security features. However, it presents the most important variation points related to online catalogs. The UML-F Web site http://www.UML-F.net provides the Java source files and some sample adaptations of WebShop.

Motivation & Objective

• To illustrate the practical application of UML and UML-F in modeling web-based e-commerce systems.
• To provide a structured framework for understanding key architectural variation points in online catalogs.
• To serve as an educational reference for software engineering principles in web application development.
• To demonstrate how domain-specific modeling can simplify the design of complex web systems.
• To offer a foundation for exploring extensibility and customization in e-commerce platforms through formal modeling.

Proposed method

• The framework is developed using UML and UML-F to model the structural and behavioral aspects of an e-commerce system.
• Core components include product catalog management, user interaction flows, and order processing logic.
• The design emphasizes modularity and extensibility through well-defined variation points in the online catalog domain.
• The framework is implemented in Java, with source code and sample adaptations available via the UML-F website.
• The system is intentionally minimal, omitting production-grade features such as authentication and encryption.
• The approach uses model-driven engineering principles to guide implementation from high-level UML models.

Experimental results

Research questions

• RQ1 How can UML and UML-F be effectively applied to model the core functionality of a web-based e-commerce application?
• RQ2 What are the key variation points in online catalog systems that can be systematically modeled and abstracted?
• RQ3 To what extent can a UML-based framework serve as a pedagogical tool for teaching e-commerce system design?
• RQ4 How does modeling with UML-F support the separation of concerns and extensibility in web application development?
• RQ5 What are the limitations of using a minimal framework like WebShop for real-world e-commerce deployment?

Key findings

• The WebShop framework successfully demonstrates the use of UML and UML-F in modeling a representative e-commerce system.
• The framework identifies and structures key variation points in online catalogs, such as product display and search logic.
• The absence of security and production features confirms its role as a teaching and illustration tool rather than a production system.
• The availability of Java source code and sample adaptations supports hands-on learning and model-driven development experimentation.
• The framework serves as a valid reference for modeling complex web applications using formal modeling languages.
• The approach enables clear separation of concerns and supports systematic extension through defined architectural patterns.
