StarUML 2 is compatible with UML 2.x standard and supports totally 11 kinds of UML diagrams: Class, Object, Use Case, Component, Deployment, Composite Structure, Sequence, Communication, Statechart, Activity and Profile Diagram.
You can create Entity-Relationship Diagrams (ERD). ERD is one of the most frequently used diagram for database modeling. Our ERD is based on crow’s foot notation which is much easier and readable than Chan’s notation.
Creating elements and connecting them are somewhat tedious tasks. StarUML 2 supports many shorthands in Quick Edit to create elements and relationships at once such as sub-classes, supporting interfaces, etc.
StarUML 2 supports Retina (High-DPI) Display. All diagrams, texts and icons are razor sharp. You can also get diagrams as the high-dpi bitmap images (PNG and JPEG).
You can easily find and install extensions via Extension Manager from official extension registry or Github repositories.
Many extensions are open source and hosted on Github. Fork one and make your own.
(Extensions on Github)
StarUML supports major programming languages including Java, C#, and C++. You can generate source codes from your models or build a model from source code by reverse engineering. Extensions providing code engineering can be installed via Extension Manager. Source codes are available in Github. (Java, C#, C++)
A lot of UML model validation rules have defined for StarUML and the rules are checked asynchronously whenever you save or open your model files.
Do you need to share your models with many analysts, archiects, and developers? It's easy to do that by just publishing HTML Docs. The generated HTML docs can be viewed with most of web browsers.
Supports exporting diagrams to PDF for clean printing. You can select page layout (portrait or landscape) and page sizes (B5, B4, A3, A4, Letters, etc.). You can also export all diagrams at once.
Using markdown extension, you can use markdown syntax to edit element's documentation with support of markdown syntax highlighting and preview.
