Modeling a software system requires describing multiple models because it is not enough to describe the system with a single perspective, so we typically make multiple models such as Use-Case Model, Design Model, Component Model, Deployment Model, or others in a Project.

Typically Project is organized as a set of UMLModels, UMLPackages, or UMLSubsystems. If you want to know more about UML Elements, please refer to OMG UML Specification.

Model vs View

Many users are confusing the difference between diagramming or drawing tools such as Microsoft Visio and modeling tools such StarUML or Rational Software Architect. First you need to understand a diagram is not a model.

Model or software model is a description of any aspect of a software system such as structure, behavior, requirement, and so on. A software model can be represented in textual, mathmatical or visual form. A Model element is a building block of a software model.

A Diagram is a visual geometric symbolic representation of a software model. A software model can be represented in one or more diagrams with different aspects. For example, a diagram can focus on class hierarchical structure while another diagram can focus on interaction between objects. Diagrams consists of view elements, which are visual representations of a model element.

A model element may have multiple corresponding view elements. A model element has its own data such as name, stereotype, type, etc. A view element just renders the corresponding model element in a diagram. View elements may exists multiple times in a diagram or in different diagrams. If the name of a model element changed, all corresponding view elements reflect the changes in their diagrams.

Fragment

A fragment is a part of a project saved as a separate file with the extension name .mfj. Any element can be exported as a fragment, but typically UMLPackage, UMLModel, and UMLSubsystem are the candidates. Once a fragment is exported as a file, the fragment can be reused by importing in a project.

Profile

UML (Unified Modeling Language) is so general-purpose modeling language that could be used to express any kinds of software-intensive systems. In this reason, using UML for a specific domain or platform is not sufficient, so you may need to define UML Profile. StarUML provides UML profiles which can be used to expand UML. For example, UML profiles can be used for the following purposes.

Profiles for specific programming languages (C/C++, Java, C#, Python, etc.)

Profiles for specific development methodologies (RUP, Catalysis, UML Components, etc.)

Profiles for specific domains (EAI, CRM, SCM, ERP, etc.)

Extension

An extension is a package which adds new features to StarUML. For example, an extension can extend menus, UIs, dialogs, modeling notations, preferences, etc. An extension can be written in JavaScript, CSS3, and HTML5 and can use Node.js integrated in StarUML. Extensions can be easily installed, uninstalled, and updated via the main extension registry.

FAQ (Frequently Asked Questions)

License

Is StarUML open source?

No. StarUML V1 was an open source project under GPL License. However, current StarUML (after V2) is not open source any more. Many users have been expected that the project is being continued, developed and maintained. But, we couldn’t find any sponsors so we can’t avoid to commercialize this product in order to keep developing and supporting users.

Can I still use StarUML V1?

Yes. you can use StarUML V1 for any purpose. However, don't forget that the StarUML V1 is no more maintained and cannot be supported.

Purchased license is perpetual or time limited?

License is perpetual, so you can use forever with the purchased version. However, you need to pay to upgrade to new major versions.

What is the difference between evaluation and purchased license?

In evaluation mode, there will be watermarks in the exported diagram images. There is no time limit for evaluation, but it is only allowed for evaluation purpose. If you want to use for other purposes including educational, personal, or commercial purpose, you need to purchase licenses.

What is the difference between personal license and commercial license?

Commercial licenses are the standard licensing option for companies. They can be used by anyone working for the company. On the contrary, personal license is the licensing option for a private individual purchasing.

Can I use my personal license at work and at home?

Yes, you can. But your license can not be shared with other colleagues.

Can I use my personal license on 2 different machines at the same time?

Yes. you can install on multiple machines owned by you, but it is not allowed to install on other's machines.

Can I use company's commercial license at home?

No. Employees should not use a commercial license at home, unless on a work computer or for work purposes. Commercial license cannot be shared with other companies or individuals.

Why my license key is not working?

First, please check the correct “Name” (License Holder) and “License key” in the license email. Enter the name (your name for personal/educational license, company name for commercial license) used when purchasing for the “Name” field. It’s still not working even If you confirmed the correct name and license key. Please try restarting StarUML or rebooting OS. Most of these problems will be resolved by just restarting or rebooting. If the above trials are failed, you need to deactivate proxy server. You can do this in the settings of Internet Explorer if you are using Windows.

Sales

Can I get a refund?

Refunds are available within 30 days of purchasing. Please send us an email (support@staruml.io) if you wish to claim a refund.

Should I pay to update or upgrade to newer versions?

You can freely update to minor updates, but you may need to pay to upgrade to major upgrades. Upgrade fee will be much cheaper than purchasing new one.
