Object-oriented analysis and design

Chapter : 5 Aspect-oriented Secure Software Modeling Object Oriented Programming (OOP) [1] uses encapsulation and abstraction through class that captures both functionality and behavior and internal structure. In the software system development, besides the basic functionality, there are another concerns as synchronization, distribution, logging, error handling, security management, etc. If each one of these concerns are processed independently from the remaining part of the system, the…

The Object Management Group (OMG) The Object Management Group (OMG) is an international, open membership, non-profitable technology standards consortium, dedicated to the creation and maintenance of computer industry standards. Founded in 1989, some of the founding companies include IBM, Apple Computer, Hewlett-Packard and American Airlines. Christopher Stone and John Slitz were among the founding executive team. The management team since 2012 now includes Richard Soley-Chairman and CEO, Bill…

based GORE approach to handle the requirements conflict problem in GORE. Introduction Requirements Engineering (RE), is the first step of software engineering that deals with all process of software systems requirements like elicitation, validation, analysis, etc. Requirements engineering must address the reasons why a software system is needed, the functionalities that the system must provide to achieve its purpose and the constraints on how the software must be designed and implemented [2].…

According to Larman, software development is a method used to create, design, and maintain software. In particular, the prevalent Unified Process (UP) is an iterative software development method used to build object-oriented systems. Larman describes the iterative development and Agile Methods as a process of organizing a short series of small projects with fixed time constraints, known as iterations, which also have separate analysis, design and implementation, validation requirements. The…

Architecting and Designing Software Process of design In terms of software engineering, design can be described as a process to overcome problems that can arise within the proposed system’s functional requirements and the constraints set to ensure quality. All these problems must then be solved whilst keeping in mind the 11 principles of software design. Underneath the overlying problem lies a set of sub-problems that exist within the proposed system design. It can be said that these…

The waterfall method of development is a sequential design model, used in software development processes. The process flow is downwards like a waterfall, through the phases of concept initiation, analysis, design, construction, testing, production/implementation and maintenance. The Waterfall model is typically associated with the development of software. It can however, apply to projects that do not have a technology/software component. Its origins stem from the hardware domains of…

1. Define and describe the three stages of Design Psychology 1) The first stage, low-level property extraction. This stage consists of detection of shape, spatial attributes, orientation, color, texture, movement and often called “preattentive” processing. Important characteristics of Stage 1 processing include: • Rapid parallel processing • Extraction of features, orientation, color, texture, and movement patterns • Transitory nature of information, which is briefly held in an iconic store •…

SYSTEM ANALYSIS, DESIGN & METHODOLOGY 3.1 INTRODUCTION Crystography is basically the adoption of two information hiding techniques and fusing them together in order to enhance data security. This concept is aim at intensifying security in instances in which data confidentiality is of utmost importance. This technique of data hiding enhances security since it involves the combination of two strong techniques. It would not only encrypt the data but also hide them in an unattractive body. The…

• Not a good model for object-oriented projects. • Poor model ongoing projects. Iterative Model design Iterative model process starts with a simple implementation of the software requirements and iteratively enhances the evolving versions until the full system is implemented. At each iterative design modifily and new functional capabilities are added. The basic behind this method is to develop a system through…
