What Altova UModel is
Altova UModel is a Windows desktop tool for visual UML modeling, code generation, and reverse engineering programs into diagrams. It supports all 14 UML diagram types, as well as UML-style diagrams for XML Schemas and SQL database tables. UModel can generate Java, C++, C#, and Visual Basic .NET code and synchronize models and code in both directions. Projects can be divided into subprojects for simultaneous editing and merged. XMI import and export supports UML project exchange, while COM-based and Java-based APIs provide automation and project manipulation. Professional Edition adds SysML and BPMN, UML database diagrams, and Visual Studio and Eclipse integration. Enterprise Edition adds Model Driven Architecture support for platform-independent models. The Basic Edition costs $209, paid once for one user; Professional costs $349, paid once, and Enterprise costs $429, paid once. A fully enabled 30-day evaluation license is available after downloading and installing the software. Supported systems include Windows 10, Windows 11, and Windows Server 2016 or newer.
