Altova UModel 2026 Basic Edition2026.02.00

Create visual software designs in UML, then generate Java, C++, C#, or Visual Basic .NET source code and project documentation from those models. Altova UModel 2026 Basic Edition can also reverse-engineer existing programs into UML diagrams, allowing developers to refine the design and regenerate synchronized code as part of a round-trip workflow.

Its modeling workspace covers all 14 UML 2.5 diagram types, all nine SysML diagrams, business process modeling through BPMN, database modeling, and XML Schema modeling. Database support includes UML-style representations of tables in popular SQL databases, while XML Schema structures can be modeled alongside application designs. Source-code engineering and XMI model interchange support collaborative development and movement of models between compatible tools.

Users can tailor diagram size, position, colors, typefaces, and line styles, with dedicated toolbars, color-coded icons, entry helpers, and quick editing buttons for different diagram types. Software architects, developers, and development teams can use it to capture requirements, explore application structure, document systems, or improve an existing codebase before implementing changes.

The 2026 release updates database support and adds further new features. Published by Altova, version 2026.02.00 runs on Windows using x86 architecture.
