Object Oriented View : Problem And Infrastructure Domains

Microsoft attempts to incorporate the accessibility into design, planning, development, documentation, testing and research (Microsoft, 1). The strategy of accessibility is to continue longstanding leadership and commitment in arising innovative solutions. Moreover, they focus on their strategy of making their computers’ easy and utilize by developing accessibility into Microsoft services and products. Microsoft focuses on innovation of accessibility in community development and encourages the innovations for the industry. Microsoft focuses on the strategy of reducing complexity of accessible development by including features in visual studio and tools for making the apps

Patterns support high-level and reuse concept. By using these patterns we can adapt the implementation to suit the system that we are developing. Patterns are a great idea but we need experience of software design to use this pattern in effective way. We need to recognize situations where a pattern can be applied. The one who don’t have any experience also read the pattern books, should always able to find it hard to decide whether they can reuse a pattern or need to develop a special purpose solution.

Design involves translating the identified requirements into a logical structure and consists of "defining the hardware and software architecture, components, modules, interfaces, and data to satisfy specified requirements It involves defining the hardware and software architecture, specifying performance and security parameters, designing data storage containers and constraints, choosing the IDE and programming language, and indicating strategies to deal with issues such as exception handling, resource management and interface connectivity. System design helps in specifying hardware and system requirements. The system design specification is a starting point for the next phase of the model.

This section gives a high-level description of the twenty-three design patterns described by the Gang of Four. Each pattern description includes a link to a more detailed article describing the design pattern and including a UML diagram, template source code and a real-world example programmed using C#.

This thesis is written within the domain of modeled software development and engineering . Through the use of Modeling Language when developing modern computer systems gives the developers the feasibility of applying formal patterns and symbols in an object oriented analysis and design (OOA/D) environment. Model Driven Development (MDD) has, throughout the last years ago of tool and technology development, developed into a solution for developers giving them the ability to define a solution while creating artifacts that becomes part of the overall solution.

Abstract: Software architecture is important because of communication among stakeholders, Design decisions for understanding software, transferable design of a system. Software architecture represents a common design of a system that most if not all of the system 's stakeholders can use as a basis for mutual understanding, negotiation, agreement, and communication. Software architecture manifests the earliest design decisions about a system, and these early bindings carry weight .It is also the earliest point at which design decisions governing the system to be built can be analyzed. Software architecture constitutes a relatively small, intellectually understandable model for how a system is structured and how its elements work together, and this model is transferable across systems. There are different types of architectural styles: Distributed architecture, data flow architecture, implicit asynchronous architecture, data centered architecture, hierarchical architecture and interaction oriented architecture. This paper compares all the architectural styles and aspects of comparison are category, styles, advantages, disadvantages, examples.

The patterns exhibited are described in very concise and restricted examples that lack a comprehensive context in order for the reader to gain a full understanding of the use of the pattern in question. The patterns throughout the book are also presented in isolation to each other which hinders the illustration of pattern interaction and thus the full benefit to those wishing to learn how to implement design patterns.

Class Performance: This work made classes have enough attributes and enabled them to improve performance as a refining object-oriented system by deleting unnecessary relationship of classes on applying various equipment in object-oriented supporting for software system refining.

“The totality of features and characteristics of the entity that bear on its ability to meet stated and implied needs”

Over the past few decades, many software development methodologies have appeared and these methodologies address most of the phases of software life cycle from requirements to maintenance. In the last twenty years, there has been increasing popularity for object-oriented programming. Hence, the interest to research on object-oriented methodologies has increased. Also, there has been exponential growth due to the increase in number of software systems being described as object-oriented. Many programming languages, office information systems, system simulation and artificial intelligence have adopted object-oriented technology. It is an assumption that learning specific development method or a set of tools.

Since most of the popular programing languages used today are object oriented in nature, which in turn, is not a language, but a set of ideas that is supported by many languages, part of my research will be focused on how these concepts came into play and the rest will be aimed at collecting arguments to elaborate distinction and similarities between the two paradigms.

An architectural design performs key functions, and is of crucial importance in software engineering during the phase of software development where the essential requirements of reliability, cost, and performance are determined. Architectural design provides the definition of the abstraction level at which the software design specifies both the functional and performance behaviors of the system, and the guidelines for enhancing the system by

In the start of testing process the basic and primary thing is requirements of development cycle, this phase the testing will be easier for testing.
