Visual Modeler is a graphical object modeling tool that is tightly integrated with Microsoft Visual Basic 5.0. Visual Modeler allows you to fulfill the promise of object-oriented programming by quickly and easily creating applications that are maintainable, have a long lifetime, and are comprised of components that can be reused in other applications. 

These are the main features of Visual Modeler:

· Class diagrams - the design of the system you are about to develop in terms of a model, using a high level of abstraction. The diagram notation provided by Visual Modeler is a subset of the modeling constructs defined by the Unified Modeling Language (UML).

· Code generation - the ability to automatically generate Visual Basic code from the design model you have created with Visual Modeler. 

· Reverse engineering - the ability automatically create or update the model with changes made to the Visual Basic code. 

· Round-trip engineering - the combination of modeling, code generation, coding, and reverse engineering.
