A profile allows UML to be extended for use with a particular programming platform or to model systems intended for use in a particular domain. A profile extends the UML to allow user-defined stereotypes, meta-attributes, and constraints.

The wolf-moose relationship will first be modeled using UML. The purpose and requirements of the conceptual model will be captured using UML via use case diagrams. Furthermore, a class diagram will be used to document the system components, and a state diagram will be used to capture the possible states of a wolf and moose. The state diagram may also be used as a building block for possible Markov Chain and Bayesian Net models. Sequence and Activity diagrams will also be generated to model the dynamic behavior of the predator-prey relationship. This model will be particularly useful for building a dynamic model.

was to give efficient and flexible performance making it a versatile language that has found its place in a

The above diagrams give us a perfect scenario of all the functions which can be easily accessed by a user to make the different diagrams.

You work as a junior technician in a small organization, Salchester PollUTest, which has recently started up following a split from a parent company. The managing director of the new organization, Gary, is looking to enhance the basic computer system that he currently has.

The implementation phase of the project is where the detailed design is actually transformed into working code. Aim of the phase is to translate the design into a best possible solution in a suitable programming language. This chapter covers the implementation aspects of the project, giving details of the programming language and development environment used. It also gives an overview of the core modules of the project with their step by step flow.

Nowadays, there is no stable model transformation approach for mobile application. Model transformation is one of the prominent features and the rising research area of Model Driven Engineering (MDE). There is still gap between software designer and developer because of the heavyweight of graphical modeling language like Unified Modeling Language (UML). The textual modeling language attempts to fill the gap between modeling and implementing in the development lifecycle. The proposed research work intends to transform text-based model oriented program to mobile application. UML Programming Language (Umple) uses the concept of textual modeling as a technique to reduce differences between the model and the code. The technique of model transformation is defined by meta-model and transformation rule. The proposed work intends to construct the source meta-model for model oriented program and the target meta-model for mobile application. And it also intends to define model transformation rules to bridge the gap between source and target meta-model by using ATLAS (ATL) transformation language. The proposed system expected to generate the android source project and create, retrieve, update, and delete (CRUD) android apps.

The main advantage of this approach to benefit from the UML standard modeling notation and the training done with software engineers to model the software with the UML notation

The class diagrams are extensively used for the modeling of object oriented systems because they are the only UML diagrams which can match directly to object oriented language. The class diagram shows a set of classes, interfaces, associations, collaborations and restrictions. It is called a structural diagram.

Object-Oriented Programming enables programmers to program by modeling the real world instead of defining the logic of how the world works. It focuses more on what makes up an object rather than what the object does. Programmers can focus on creating small components or objects, and group them together based on their relationships to build a larger object, which can be built upon again in future. The process of developing the paradigm consists the following steps: Encapsulation, Inheritance, Data Abstraction, and Polymorphism.

There are two types of Data Flow Diagram. Here 0-level DFD shows whatever user can do through giving input and application return desired output to the user. And 1-level DFD shows the how the application works. Both DFD are

The multi-language capability of the .NET Framework and Visual Studio .NET enables developers to use their existing programming skills to build all types of applications and XML Web services. The .NET framework supports new versions of Microsoft’s old favorites Visual Basic and C++ (as VB.NET and Managed C++), but there are also a number of new additions to the family.

some developers like Jacobson et al, Rumbaugh et al, Booch developed competing object oriented software engineering methods. Unified modeling language (UML) is developed in mid 1990s by combining such previously developed software engineering methods. Object management group(OMG) took control of UML formal evolution in to its hand. It is largely used as it is considered as a modeling standard for object oriented software development. Some books, articles and contributions are done by the researchers for defining various aspects of the software and guidelines on how to use this language. It is important to remember that UML is a language not a methodology, so that we cannot have consistent guidelines. They even did a examination on unified modeling language because of its widely acceptance. They even got little evidence on the level and nature of unified modeling language use. There study included seven unified modeling language components which are used in system analysis and design. Which addressed three key questions they are firstly, to what extent and purposes can unified modeling language analysis components can be used. secondly, does the complexity of the language is due to the differences in the levels of component use and do such differences exist or not?.thirdly, do UML is successful in establishing proper communication between the software

A use case diagram is a type of behavioral diagram defined by the Unified Modeling Language (UML). Its purpose is to present a graphical overview of the functionality provided by a system in terms of actors, their goals- represented as use cases- and any dependencies between those

The interface components provided by the Visual programming environment has some code built into them. For e.g., a button ‘ Knows’ when it has been clicked upon and then when the event occurs, it executes the appropriate code.
