PPOOA (Pipelines of Processes in Object Orientes Architectures) is an architecture modeling tool based on UML notation and using the PPOOA methodology. The tool is offered free as an addon of Microsoft Visio 2003. PPOOA tool supports two types of diagrams:
- One based on UML class diagram may be used to represent the structural view of an architecture.
- The other diagram is based on UML activity diagram, and is used to represent each system response to an event either external, internal or timed.

PPOOA tool supports traceability between the actions in the activity diagram and the system component that performs the action. PPOOA tool supports model checking and an automatic help. The architecture documentation is generated automatically by the tool. PPOOA tool is interoperable with the University of Brest Cheddar tool for schedulability analysis and real-time systems simulation. PPOOA tool generates an XML file of the architecture developed that can be processed by Cheddar tool. The user can then evaluate the RTS behaviour.

ModelRight 3 can reverse engineer your existing database to get a graphical view of it, generate all the SQL statements to create the database, or synchronize your database model with the database to keep your design up to date. ModelRight 3 has more complete and in-depth support for your database.ModelRight 3 has more complete and in-depth support for your database's (currently Oracle, SQL Server, MySQL, and database via ODBC) most advanced features. Plus, it has a sophisticated modern user interface that allows for easy diagram editing and navigation.

Entity Relationship Designer written totally in java and based on Mogwai ER Designer. Includes ability to connect to several data sources including mySQL.

PlantUML is an open source tool that allows to quickly write all Unified Modeling Language (UML) diagrams: sequence diagram, use case diagram, class diagram, etc.

The RE-Tools is a model-based modeling tool. All supported notations can be used together in an integrated manner, which means functional and non-functional requirements, agents, goals, softgoals, formal goals, and objects can be related as needed.

The ObjectAid UML Explorer is an agile and lightweight code visualization tool for the Eclipse IDE. It shows your Java source code and libraries in live UML class and sequence diagrams that automatically update as your code changes.

Systems engineering, software development and testing automation

The Telelogic Tau® product family automates design and development best practices for:

Project conception and requirements visualization
Systems engineering
Defense systems architecture
Software development for embedded systems and other advanced systems
Testing
With Tau's powerful graphical modeling capabilities, users can:

Specify all aspects of a system's design
Simulate and verify its behavior
Ensure the design is on the right track, even at the earliest stages of the project
Generate code from the validated model
Define, generate, and execute tests against the models
Tau supports the industry standards for visual modeling - UML™ (Unified Modeling Language™) 2.0, SysML (Systems Modeling Language), and SDL (Specification and Description Language), conformance, systems and integration testing (TTCN-2 and TTCN-3), and defense system architectures (DoDAF).

WinA&D is a comprehensive tool for system modeling and simulation, requirements management, structured analysis and design, object-oriented modeling with UML and data modeling of information systems. It has diagram editors for process models, data models, class models, state models, object models, structure models and task models. Each model shows a different view of the software system integrated through a global data dictionary. Dictionary and model information can be used to generate code for several languages including C++, Java, Delphi, Ada and SQL. Dynamic systems can be modeled, parameterized, simulated and charted. The tool provides requirements specification and traceability, design verification reports and text import/export features. The integrated report generator includes dozens of standard reports plus a scriptable environment for creating custom reports. The Site License edition supports multi-user team dictionary and requirement documents making it well suited for team development.

ECO IV is the latest release of "Enterprise Core Objects", an application framework that allows you to take applications from design to implementation in a much shorter time. ECO enables you to easily implement your applications as business classes rather than traditional data access. Instead of accessing the database directly your application will interact with the business classes you have designed using the UML. This approach ensures uniformed behavior throughout your application, and even across multiple applications if you choose to reuse your UML packages in more than one application; for example if you choose to implement both an ASP .NET and WinForm version of your application.

UML tool where you can develop at model level and automatically generate source code for C++.
