Astah supports the UML 2.x. requirements for Class(Object/Package/Robustness), UseCase, Sequence, Communication, Statemachine, Activity, Component, Deployment, and Composite Structure Diagrams. Many models are easily converted between different UML 2.x diagrams such as Mind Maps, ER Diagrams and more.

Astah, is a UML editor integrated with Mind Mapping features that is ideal for planning, collaboration, and design. It supports the UML 2.x. requirements for Class (Object/Package/Robustness), UseCase, Sequence, Communication, Statemachine, Activity, Component, Deployment, and Composite Structure Diagrams.
In addition, the editor enables users to create Data Flow Diagrams that show how data flows between systems. DeMarco and Gane/Sarson notations are supported in Astah Professional. And with Astah DFD diagrams they can create Data Flow Diagram (External Entity, Process Box, Data Store, Data Flow), add models in Data Flow Diagram to CRUD Functions and convert Mind Map Topics to elements in Data Flow Diagrams. Astah can be tailored to fit its users’ needs through the use of free add-ons.
It has various Plug-ins available for free to integrate with some of the best tools available, and to further expand the capabilities of Astah. If none of the Plug-ins in their current library does exactly what its users want they can create their own or send Astah a request. However, if the editor works as expected then users can copy and paste diagram images into Microsoft Office documents as vector (SVG, EMF), JPEG and PNG formats. Vector (SVG, EMF) format that will stay as clear as the original with resizing and modifying are available.
Users can also set files (.txt, .asta, .xls, .doc. etc.), URLs and other models in the project as the target for hyperlinks. For example, if a user creates a Mind Map as a sketch, he/she can create a Class Diagram based on it and set hyperlinks with both diagrams.
