A. Investigate the Unified Modeling Language on the Web. Write a paragraph news brief describing the current condition of the UML. Business worldwide has moved into an interval dominated by rapid discontinuous change in procedures. The introduction of Internet technologies and the globalization of production have changed the way business is changing.
Previously change has been more incremental than innovative. Change in the 21st hundred years is generally radical and dramatic. The production of software to support business procedures was limited in scope. Information Systems departments developed departmental applications like a payroll or inventory system. The processes, methods, and tools used by software development organizations suited this kind of problem.
The analysis focused on extracting requirements for the software from the departmental staff. The culmination of the techniques is embodied in the Universal Modeling Language (UML) where at the best level of abstraction the relationships between the users (called Actors) and the program system are referred to in terms useful Cases. These UML approaches have been refined over the years to effectively develop such systems. Enterprise Resource Planning (ERP) software took the next steps to tie departmental software together into workflows stretching the limits of UML. The broadest application of UML includes software systems and their users.

- Estimate time or financial resources needed to complete projects
UML does not address business concerns except to the degree that they directly impact the design of the software. UML covers the definition, design, and development of software, but it needs to be placed in the context of the business. B. Investigate Rational’s Unified Process (RUP) on the Web. RUP is a commercial version that extends aspects of the Unified Process. Write a brief memo explaining how it is related to the Unified Process as referred to in this chapter. By spotting software development as a tactical business process – a series of related activities that needs to be integrated and computerized – organizations can transform their software development activities into a source of strategic advantage.
In so doing they embrace a business-driven software development process that yields both top-line business benefits and bottom-line productivity improvements. These organizations use software development to drive their business success. · Open and extensible. Microsoft .NET, BEA and Oracle solutions. Rational software is based on the structure and theory of UML, uML is simply a tool to record system design however.
Rational will go another step and allows an individual to create software with additional business designs and components, as well as facilitates communication and business of the task. These additional functions create an effective tool for enterprise level application. C. Investigate the thing Management Group (OMG) on the net. Write a report describing the purpose of the OMG and what it is associated with, besides the UML. MDA is dependant on the idea of modeling with UML.
At the center of MDA can be an approach to design based on dealing with it as something, than a process rather. Non-MDA approaches treat design as a process in which developers apply their expertise to handcraft elegant solutions from often ill-defined problems. The total result is working code. The design is not captured explicitly, but instead smeared over the code as a set of results of a skilled thinking process.
In an MDA strategy, promulgated by OMG and based on the ongoing work of Shlaer and Mellor, and others, the look is itself something that is expressed as a set of formal mapping guidelines. In MDA the application model is generalized as a platform-independent model1, or PIM, visualized using standard UML usually, and the platform for formal change rules happens to be being standardized as the QVT (Query, Views, and Transforms) specification.
The result of the transformation can either be another, platform-specific, model (PSM), or components of the target program, such as data source schemas, deployment scripts, test scripts, or indeed executable code. In the latter case, the PIM must be behaviorally complete, defining business logic in terms of abstract actions. D., Look for a set of CASE tools using the net that support the UML.
