STICK-MEN AND OVALS The sample diagrams provided with Rose describe a university course registration system, documented in the book Visual Modeling with Rational Rose and UML (Addison-Wesley Publishing Co., 1998), by Terry Quatrani and Grady Booch.

This way, components can be reused in other component-based applications. Component diagrams in Rose carry out component-based development: Each component fulfills a specific system function components then interact with each other to achieve the overall functionality of the system. Eight of UML's nine diagrams are supported by Rose. The language models data, processes, objects or components. UML Version 1.1 is the latest de facto standard visual modeling notation. Rose also supports the COM/DCOM (ActiveX), JavaBean and Corba component standards. Rose supports multiple programming languages (C++, Visual Basic and Java) in the same model, and is extensible by way of add-ins and partner products available from third-party firms. Rational Rose, a design tool from Cupertino, Calif.-based Rational Software Corp., achieves visual modeling through use of the Unified Modeling Language (UML) and component-based development. This allows for iterative development, which builds functionality gradually. Visual modeling gives a development team a bird's-eye view of a system and its component interactions without getting caught up in the details too soon.

A picture is worth a thousand words, and so it is with software design.

When drawing generalization or realization hierarchies on a diagram always make sure the parent elements are higher than the child elements so the arrows always point upwards.

When drawing connectors, having lines with multiple connectors make diagrams look messy and confusing.

Try to make sure all lines go horizontally or vertically and create right angles with each other.

If two lines must cross, use a “bridge” to show that the lines do not intersect. This allows your diagrams to be more readable and understandable.

Avoid lines crossing over each other while creating UML diagrams.

When creating UML diagrams with Creately’s UML diagram tool you can create multiple diagrams on different workspaces and link them together for better comprehension. Creating unnecessarily complex diagrams with too much information can confuse stakeholders.

When creating UML diagrams it is important to remember to create levels of abstractions that meet the need of your audience.

Things to Remember While Creating UML diagrams UML diagrams visually represent a system along with its main actors, roles, actions, artifacts or classes, in order to better understand, alter, maintain, or document information about the system. UML or Unified Modeling Language is a modeling technique used to document software.
