Visual Studio .NET 2003 provides developers with comprehensive tools for designing and building distributed applications for Microsoft Windows, the Web, and mobile devices. Visual Studio .NET 2003 Enterprise Architect (VSEA) builds on the power of Visual Studio .NET 2003 Enterprise Developer by including additional capabilities for designing, specifying, and communicating application architecture, development best practices, and application functionality. Use Microsoft Visio–based Unified Modeling Language (UML) to specify and communicate application architecture and functionality. Generate skeleton code to create starting implementations, and use reverse-engineering capabilities to document existing implementations in all Visual Studio .NET programming languages. Capture business requirements easily with Visio-based conceptual modeling. Full roundtrip engineering with logical and physical data models enable communication from the business analyst to the database designer. Senior developers and architects can customize Enterprise Template projects to provide application starting points for less-experienced developers, increasing development team productivity. Build reusable components to simplify common programming tasks. Use Enterprise Instrumentation Framework components to simplify application manageability and instrumentation. And use the .NET Framework and Microsoft Windows Server 2003 to develop distributed applications with improved deployment capabilities, security, reliability, and performance.
