The Unified Modeling Language (UML) is a highly abstracting language designed to provide abstract models of diverse systems. UML is currently in version 2.1, but has been criticized for its gratuitous constructs that would be more appropriately added via libraries; its imprecise semantics, which are the result of the fact that UML is a combination of multiple legacy standards; and over-generalization, in that UML has perhaps been abstractified to the point that it is no longer specific to anyone, but neither is it useful to anyone. The next version, 3.0, will be addressing these issues, though perhaps not solving them. As a young language, UML still has time to develop into a more robust and productive tool.
The Object Management Group (OMG) is a not-for-profit company that creates and supports technology-related, object-oriented standards. OMG created the standard for UML, and still has ratifying influence over its development. OMG is a supporter of modular and object-based software development, which provides ease of design, improved revision, and reusable code. Object-oriented development is highly reliant on abstraction, a method of restricting the flow of information between objects in order to create processes that can be reused. This method of coding is (theoretically) the type of coding that UML enforces.
The Rational Unified Process (RUP) is a standard that describes the development of a complex software solution. It is broken into four steps: inception, the phase in which profit and revenue models are constructed to generate a timeline for development; elaboration, the phase in which the project scope is more thoroughly detailed; construction, the phase in which components and features are designed; and transition, in which the product moves to the end user. This process is used in the context of iterative development, which encourages the solution to be scaled to its final state in steps; ideally, those steps result in a result reviewable by the end-user, which provides an opportunity for revising and refining of the project scope.

Object Oriented Hypermedia design model and the four-step process involved in the development of the model. This section will provide an explanation for each step in the process. Then we will discuss the past, present and future business uses of the model. This will explore the importance of the model in business applications that are conducted through the Internet. We will also provide details about the compatibility of the
Rational XDE modeling tool We recently received the Rational XDE modeling tool for use in class and luckily I had some previous practice using it. "XDE Professional, originally released in February, is a tool that allows software developers to "model" -- or create graphical representations of -- their software, so they need to write less code to build applications." (Wong, 2002) This report aims to describe my understanding of XDE and
Stage 1 or Understanding the Problem The RUP recommends using business use cases for locating purposes which have two qualities:(1) easy to understand and (2) easy for the client to use. The RUP does not clarify how these "use cases" should be analyzed to determine what is in the NIMSAD purview. To identify sections of the business that need to be examined, ETHICS uses a stakeholder method that demonstrates all parties
This approach brings down the costs involved, the chances of delay in product release and the gives the user an option to update their requirements in successive iterative steps (Jacobson & Rumbaugh 1999, pp. 3-13). CHAPTER 2 Oracle and Microsoft SQL Server are among the most widely used databases with a large range of features with regards to their techniques of development and deployment. Both the Oracle 10g and SQL Server
The reward for the effort of learning is access to a vocabulary that is shared by a very large population across all industries globally" (p. 214). Moreover, according to Bell, because UML is a language rather than a methodology, practitioners who are familiar with UML can join a project at any point from anywhere in the world and become productive right away. Therefore, Web applications that are built using
Generally, the classification of model transformation tools is based on whether it is declarative or operational, directionality or multiplicity. The study further discusses the sub-categories of model transformation that include: hybrid transformation tools, graph transformation, relational, template based, operational based, structure driven and direct manipulation. All the sub-categories of model transformation have the following features: Hybrid transformation combines two or more transformation approaches; Graph transformation focuses on graph rewriting over variation and extensions of labeled
