●The traditional model for systems development was that an IT department used (71)which is a process-centered technique, and consulted users only when their input or approval was needed. Compared with traditional methods, many companies find that JAD allows key users to participate effectivelyin the (72). When properly used, JAD can result in a more accurate statement of system requirements, a better understanding of common goals and a stronger commitment to the success of the new system. RAD is a team-based technique that speeds up information systems development and produces a functiog.information system. Whilethe end productof jAD is a(an)(73),theendproduct of RAD is the (74) .The RAD model consists offour phases. During the(75),users interact with systems analysts and develop models and prototypes that represent all system processes, outputs, and inputs.

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 J2EEand.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.

The analysis phase answers the questions of who will use the system, what the system will do, and where and when it will be used. During this phase, the project team investigates ny current system,identifies (71) , and develops a concept for the new system. This phase as three steps: first, (72) is developed to guide the project team's efforts. It usually ncludes an analysis of the current system and its problems, and the ways to design a new ystem. The next step is (73) The analysis ofthis information - in conjunction withinput rom the project sponsor and many other people - leads to the development of a concept for a ew system. The system concept is then used as a basis to develop a set ofbusiness analysis odels that describes how the business will operate if the new system were developed. The set of models typically includes models that represent the (74) necessary to support the nderlying business process. Last, the analyses, system concepts, and models are combined nto a document called the (75), which is presented to the project sponsor and other key ecision makers that decide whether the project should continue to move forward
