A collection of UML 2 tools designed to help you generate code in various programming languages, such as C, Java, Idl, Php and Python

What's new in BOUML 7.9:

• When you opened a project with definitions for MySql you could have the error noaction is not a MySqlRefOption, fixed. (see Erreur : noaction is not a MySqlRefOption).
• In the editor of an operation for C++ add the check boxes volatile value, const value and const expr value all managed through the keyword ${typeprefix}, and a tab to specify formal parameters.
• Warning the keyword ${typeprefix} is only present by default in the models created from that version of Bouml. If you expect it in your existing projects you have to add it in the default operation C++ declaration/definition in the generation settings and in the existing C++ operation declaration/definitions. (see C++ function/member templates).

Read the full changelog

BOUML is a collection of useful tools designed for UML 2 (Unified Modeling Language) that will help you generate code sequences in different programming languages (MySQL, Python, C++, Java, PHP, or IDL).

In addition, the BOUML capabilities can be extended by external “plug-outs” that are included in the software distribution, or are written from scratch using C++ or Java.

Efficient UML 2 tools packed within a user friendly interface

To run the BOUML application you need to provide a license file that is available only commercially (you can visit the developer page to view the pricing details). However, to test its capabilities, you can use the BOUML Viewer application, which has several limitations.

Since BOUML comes with an organized design, finding your way around is fairly intuitive: you get to easily visualize your project’s structure and the content of each document. The best part is that BOUML uses few resources, even when dealing with a considerable number of classes.

Besides the tools that help you model processes and structures, BOUML comes with a collection of “plug-outs” designed to help you deal with repetitive tasks. In addition, the extensions will help you generate code in various popular programming languages.

Effortlessly generate code using multiple programming languages

Worth mentioning is the BOUML project control tool that helps you make sure that a file is not modified by multiple users at the same time. At the same time, the project synchro tool will synchronize the adjustments made by to different files by different users.

To conclude, if you are looking for a user friendly yet versatile UML 2 toolbox that provides support for popular programming languages and offers you the possibility to extend its capabilities by integrating plug-outs written in Java or C++, the BOUML application certainly deserves a try.
