Introduction

Object-Oriented(O-O) design tools are mainly used to create UML visual model for software design, such as the IBM® Rational Rose®, Microsoft Visio and PowerDesigner. The Unified Modeling Language(UML) is a standardized language approved by the Objective Management Group™ (OMG™). UML is used for sepcifying, visualizing, constructing, and documenting models in software systems.The UML was developed by Grady Booch, Ivar Jacobson and James Rumbaugh at Rational Software in the 1990s.<ref>Marc Hamilton (1999) Software Development: A Guide to Building Reliable Systems p.48</ref>The UML has synthesized the notations of the Booch method, the Object-modeling technique (OMT) and Object-oriented software engineering (OOSE) by fusing them into a single, common and widely usable modeling language.<ref>OMG Unified Modeling Language (OMG UML), Superstructure. Version 2.4.1 http://www.omg.org/spec/UML/2.4.1/Superstructure</ref>

O-O Design Tools

There are a lot of object oriented design tools can be used for software development.<ref>List of UML modeling tools http://en.wikipedia.org/wiki/List_of_Unified_Modeling_Language_tools</ref> Rational Rose® and Enterprise Architect are the most popular commercial design tools used for developing complex software system.

IBM® Rational Rose®

Rational Rose® is a set of UML modeling tools for software design, which is produced and marketed by the Rational division of IBM (previous Rational Software Corporation, the developer of UML). By use of Rational Rose® software engineers can create visual models of software architectures, databases, application requirements and reusable assets. The Rational Rose® product family provides a set of model-driven capabilities for developing Java Platform, UNIX and Linux Platforms, and Microsoft Visual Studio-based software applications. Rational Rose® includes tools for reverse engineering and code generation of classes and architectures, for example, it allows software developers to generate code for Java Enterprise Edition software applications from visual models using the UML. Rational Rose® supports various of software development languages, it offers round-trip engineering for Ada, ANSI C++, C, C++, CORBA, Java, MicrosoftVisual Basic and MicrosoftVisual C++ languages, as well as database designs.<ref>IBM Rational Rose Datasheet ftp://public.dhe.ibm.com/software/rational/web/datasheets/rose_ds.pdf</ref> Rational Rose® provides full team support. The team management features support the development of large and complex projects. By the help of configuration management and version control system, changes made to a model can be set available to other teammates. Rational Rose® helps teams create rich applications based on robust architectures.<ref>IBM Rational Rose Datasheet ftp://public.dhe.ibm.com/software/rational/web/datasheets/rose_ds.pdf</ref>

Enterprise Architect

Enterprise Architect is a visual modeling, comprehensive UML analysis and design tool. Enterprise Architect supports a number of methods of modeling business processes using UML as the foundation modeling language.<ref>Enterprise Architect http://en.wikipedia.org/wiki/Enterprise_Architect_(Visual_Modeling_Platform)#General_features</ref> Enterprise Architect supports round-trip engineering (generation and reverse engineering) of source code for many programming languages, such as ActionScript, C, C++, C#, PHP, Python and so on.<ref>Enterprise Architect http://www.sparxsystems.com/products/ea/index.html</ref> Like Rational Rose®, Enterprise Architect also provides full life cycle support for software and system engineering. The reverse engineering supported by Enterprise Architect can help developers visualize applications of a wide range of programming languages and database repository schema. Compare with the price of Rational Rose®($2600.00~$10,500.00), Enterprise Architect($135.00~$849) is much cheaper.

Microsoft Visio

Microsoft Visio is a diagramming and vector graphics application. In Microsoft Visio Professional 2000, it first time provide support for UML modeling. The Microsoft Visio UML Model Diagram template provides full support for creating object-oriented models of complex software system. But it only support programming languages developed by Microsoft, such as Visual Basic, Visual Basic.NET and Microsoft Visual C#.NET.
