UML-based tools are often used for J2EE/.NET application analysis and design, both because UML's object orientation is ideal for the J2EE/.NET implementation(66)and because of the expanding scope and complexity of today's enterprise endeavors.(67)the approaches diverge at the coding/implementation phase, a common set of analysis and design techniques applies to both J2EE and.NET.

 The use of a virtual machine(VM)architecture is also common to J2EE and .NET. Application development tools(68)intermediate-level code instead of platform-specific binary code, which means the VM interprets that code in real time or performs Just-In-Time(JIT)compilation; the Microsoft VM always runs JIT-compiled code. This VM-based model results in(69)-independent applications and is conducive to the late-binding technique that's(70)to the OO approach.

Due to a constantly(71)environment, a poor understanding of the user's needs and preferences, as well as a(72)of willingness to modify(73)organizational structures and decision models, the full economic potential of Web.

 Information Systems(WIS)has not been realized by now. The data object types of the(74)meta. model, the Extended World Wide Web Design Technique(EW3DT), provide hypertext designers(75)a conceptual, user-centric framework and graphical notation for the construction of both, reference and customized models, during the software development process of commercial WIS. A reference model as a normative concept represents an abstraction of a typical company, its functional units, or its(Web)Information Systems and is intended to streamline the design and implementation of complex applications at reduced costs. As precondition for pursuing a partial globalization strategy, EW3DT distinguishes between technical and content-specific responsibilities for designing, implementing, and maintaining WIS.
