ZenUML: The Best Diagram Plugin for Confluence

Understanding the Difference

Modeling and drawing serve distinct purposes in software development:

  • Modeling is the process of creating an abstract representation of a software system, encompassing aspects like structure, behavior, requirements, etc. A model provides a comprehensive description of the system to help stakeholders understand its intricacies and make informed decisions.

  • Drawing refers to the creation of visual diagrams that represent specific aspects of a software model. Diagrams communicate and illustrate concepts and relationships in the model. Drawing is a means to an end, while modeling is the foundation.

The Strengths of ZenUML

ZenUML is a powerful modeling language that allows software professionals to describe models with ease and precision.

  • Concise syntax captures the system's essence for clear and unambiguous representation.

  • Intuitive syntax enables easy modeling of interactions and event sequences.

For example:

This shows the flow of information between User and System.

This shows the interactions between client and service.

  • ZenUML can automatically generate diagrams from such code, ensuring consistency between model and visualization.
