¶ … system modeling? Do you already have them installed? If you are installing the Rational XDE, how did it go?
According to Allen McNaughton of Devx online computer magazine, the systems modeling program Rational XDE, in contrast to Microsoft's Visio systems modeling software, is by far the superior program of the two options. Unlike Microsoft's Visio, "Rational XDE supports round-trip engineering with continuous synchronization between the code and model elements that removes the need for separate forward and reverse engineering steps." Continuous synchronization within programs, says McNaughton, will be the wave of the future in modeling tools. (McNaughton, 2002)
Furthermore, within the Rational XDE program, "options are provided to control the frequency of code/model synchronization or to disable it entirely for selected elements if performance problems arise with large models," enabling users to tailor it to their specific programming needs. The program is useful as well "when approaching software design from a model-first-and-code-later perspective, as "when you use Rational XDE to reverse engineer a Web project that contains a code-behind file, Rational XDE creates an unstereotyped class in the model to represent the code-behind file." (McNaughton, 2002)
McNaughton recommends the program above its competitors unreservedly as "it is clear from the commitment the designers of Rational have made, that the software engineers view the platform "as a significant destination for new projects and for the migration of existing code bases. As such, UML and MDA tools from Rational and its competitors will become a more integrated part of the development cycle." Given the fact it is likely to be more often used by designers and programmers in the future, one would be well advised to avail one's self of the emerging technology. Although the program is not necessarily easier to install than other systems modeling tools, its greater flexibility to deal with the needs of evolving products, the ability to reverse engineer, and its streamlining of foreword and reverse engineering steps into continuous operations justify its comparative superiority to its competitors.

Decision Analysis System Modeling Using Spreadsheets" "DATA DECISION ANALYSIS SYSTEM MODELING USING SPREADSHEETS" "Data Decision Analysis System Modeling Using Spreadsheets." Spreadsheet is one of the most popular software packages on the planet. Daily, million of business people, students and individuals use spreadsheet program to build models to assist in solving decision problems they face on their work activities. Thus, employers generally look for individuals having experience and skills with spreadsheets. Typically, spreadsheets assist
Systems Media Table: Comparison System Uses Word processor The main purpose of this program is to construct sentences of the perceived information and manipulate paragraphs to form a word document. The program uses a display format 'what-you-see-is-what-you-get' to enhance the quality of the expected hardcopy. WordPerfect and Microsoft Word are mostly superseded by both organization and personal computers to perform functions such as word formatting, letter processing and some simple designing. Accordingly, it is the
However, in the most recent theory of evolution which discusses the living world appears as the result of chance and an output of different randomly selected natural mills. This kind of development came to present as a result of the need of more subjects or topics in areas such as cybernetic, general system theory, information theory, theories of games which is needed in most decision making process in line
Modeling Tool In one of my system projects, I used the Logical Data Model to build separate models for each logical entity of the project. With Logical Data Model, it allowed me to represent each area of the system with one model diagram. Thus, the entire project encyclopedia is composed of separate data models that can be assembled into one complete system. Logical data modeling can meet the needs of every system
System Design: Oahu Base Area Network The aim of this paper is to examine and discuss the Navy's decision to build the largest local area network (LAN) connecting the U.S. Pacific Fleet using information-gathering techniques and design methods. The system has the capacity to connect sailors and marines within the 102-million square miles of the Pacific Fleet's command coverage. Moreover it will provide the indispensable access for supplying and training the
Systems Thinking The key constructs of systems thinking were constituted in the first half of the 20th century in fields such as psychology, ecology, organismal biology, and cybernetics (Capra 1997). They include: sub-systems/parts/wholes, environment/system/boundary, process/structure, emerging properties, hierarchy of organizations, negative and positive feedback, data and control, open systems, holism, and the observer. The practical application of these constructs in many fields was discovered by von Bertalanffy (1950). He referred to
