Open ModelSphere is a powerful data, process and UML modeling tool - supporting user interfaces in English and French. Designed to be platform-independent, Open ModelSphere was created as a 100%-Java application. Having been developed as a commercial software by Grandite over several years, Open ModelSphere has become a professional and mature product that is supported by an experienced community of software architects and engineers who want users to benefit from the product and share their expertise with them.
Open ModelSphere is released under GPL (GNU Public License) version 3. It is a free software that can be downloaded, used, copied and modified free of charge. Open ModelSphere has a Premium version that is a flexible SQL database design tool for creating new applications as well as accessing legacy system code. In particular, Open ModelSphere Premium provides tools for conceptual, logical and physical database design. It also comes with a generic built-in interface to connect to SQL databases via ODBC/JDBC driver.
In addition, Grandite offers a range of powerful bi-directional plug-in database interfaces that are available "off the shelf". Grandite's portfolio includes migration services and development on demand to extend Open ModelSphere's functionality to additional target systems. Open ModelSphere is designed to be platform-independent; however, it has been primarily developed and tested on Windows systems. Therefore, Grandite does not provide any particular installer or any specific instructions for non-Windows environments. Users may find advice and comments from 3 rd parties on the web on how the zip installer package can be adjusted to successfully implement Open ModelSphere on non-Windows platforms.
