Design patterns being applied more and more to solve the software engineering difficulties in the object oriented software design procedures. So, the design pattern detection is widely used by software industries. Currently, many solutions presented
to detect the design pattern in the system design. In this paper, we will propose a new one which first; we will use the graph implementation to implement both the system design UML diagram and the design pattern UML diagram. Second, we will implement the edges for each one of the both two graphs in a set of 4-tuple elements. Then, we will apply a new inexact graph isomorphic algorithm to detect the design pattern in the system design.
Scrum is a structured framework to support complex product development. However, Scrum methodology faces a challenge of managing large teams. To address this challenge, in this paper we propose a solution called Scrum of Scrums. In Scrum of Scrums, w
e divide the Scrum team into teams of the right size, and then organize them hierarchically into a Scrum of Scrums. The main goals of the proposed solution are to optimize communication between teams in Scrum of Scrums; to make the system work after integration of all parts; to reduce the dependencies between the parts of system; and to prevent the duplication of parts in the system.
A Software Engineering project depends significantly on team performance, as does any activity that involves human interaction. In the last years, the traditional perspective on software development is changing and agile methods have received conside
rable attention. Among other attributes, the ageists claim that fostering creativity is one of the keys to response to common problems and challenges of software development today. The development of new software products requires the generation of novel and useful ideas. It is a conceptual framework introduced in the Agile Manifesto in 2001. This paper is written in support of agile practices in terms of significance of teamwork for the success of software projects. Survey is used as a research method to know the significance of teamwork.
Component selection is considered one of hard tasks in Component Based Software Engineering (CBSE). It is difficult to find the optimal component selection. CBSE is an approach that is used to develop a software system from pre-existing software comp
onents. Appropriate software component selection plays an important role in CBSE. Many approaches were suggested to solve component selection problem. In this paper the component selection is done by improving the integrated component selection framework by including the pliability metric. Pliability is a flexible measure that assesses software quality in terms of its components quality. The validation of this proposed solution is done through collecting a sample of people who answer an electronic questionnaire that composed of 20 questions. The questionnaire is distributed through social sites such as Twitter, Facebook and emails. The result of the validation showed that using the integrated component selection framework with pliability metric is suitable for component selection.
Electronic (E) learning management system is not a novel idea in the educational domain. Learning management systems are used to deal with academic activities such as course syllabi, time table scheduling, assessments and project discussion forums. A
lmost, all the top universities of world are using general purpose/customized solutions to manage learning management systems like SAP, Oracle, Moodle and Blackboard. The aim of this paper i.e., Mobile (M) Learning System (MLS) is not to substitute the traditional web based E learning applications but to enhance it by amalgamating both web and mobile technologies. This idea justifies the proposal of M learning system to use some of the services of E learning system from mobiles. MLS will use state-of-the-art IP Multimedia Sub System technology. The emphasis in this research will be on the technical implementation of the Session Initiation Protocol (SIP) using IP Multimedia Subsystem (IMS) to develop an MLS not only for the students of the King Abdulaziz University but it will be beneficial for the students of other universities at Kingdom of Saudi Arabia. A customized CBD is proposed as per the nature of MLS project. MLS case study is used as a research design to validate the customized CBD model. Multi-tier applications architecture (client, web, and business) will be adopted during the development of MLS case study. An MLS will be developed and tested using IMS platform to check its practicality for the students of King Abdulaziz University. It is anticipated that the proposed system will significantly facilitate to both the students and teachers of KAU during their off campus activities.
Software testing is normally used to check the validity of a program. Test oracle performs an important role in software testing. The focus in this research is to perform class level test by introducing a testing framework. A technique is developed t
o generate test oracle for specification-based software testing using Vienna Development Method (VDM++) formal language. A three stage translation process, of VDM++ specifications of container classes to C++ test oracle classes, is described in this paper. It is also presented that how derived test oracle is integrated into a proposed functional testing framework. This technique caters object oriented features such as inheritance and aggregation, but concurrency is not considered in this work. Translation issues, limitations and evaluation of the technique are also discussed. The proposed approach is illustrated with the help of popular triangle problem case study.
Agile is one of the terms with which software professionals are quite familiar. Agile models promote fast development to develop high quality software. XP process model is one of the most widely used and most documented agile models. XP model is mean
t for small-scale projects. Since XP model is a good model, therefore there is need of its extension for the development of medium and large-scale projects. XP model has certain drawbacks such as weak documentation and poor performance while adapting it for the development of medium and large-scale projects having large teams. A new XP model is proposed in this paper to cater the needs of software development companies for medium-scale projects having large teams. This research may prove to be step forward for adaptation of the proposed new XP model for the development of large-scale projects. Two independent industrial case studies are conducted to validate the proposed new XP model handling for small and medium scale software projects, one case study for each type of project.
Web application frameworks are managed by using different design strategies. Design strategies are applied by using different design processes. In each design process, requirement specifications are changed in to different design model that describe
the detail of different data structure, system architecture, interface and components. Web application frame work is implemented by using Model View Controller (MVC) and Model View Presenter (MVP). These web application models are used to provide standardized view for web applications. This paper mainly focuses on different design aspect of MVC and MVP. Generally we present different methodologies that are related to the implementation of MVC and MVP and implementation of appropriate platform and suitable environment for MVC and MVP.
Software design is one of the most important and key activities in the system development life cycle (SDLC) phase that ensures the quality of software. Different key areas of design are very vital to be taken into consideration while designing softwa
re. Software design describes how the software system is decomposed and managed in smaller components. Object-oriented (OO) paradigm has facilitated software industry with more reliable and manageable software and its design. The quality of the software design can be measured through different metrics such as Chidamber and Kemerer (CK) design metrics, Mood Metrics & Lorenz and Kidd metrics. CK metrics is one of the oldest and most reliable metrics among all metrics available to software industry to evaluate OO design. This paper presents an evaluation of CK metrics to propose an improved CK design metrics values to reduce the defects during software design phase in software. This paper will also describe that whether a significant effect of any CK design metrics exists on total number of defects per module or not. This is achieved by conducting survey in two software development companies.
Software cost estimation (SCE) of a project is pivotal to the acceptance or rejection of the development of software project. Various SCE techniques have been in practice with their own strengths and limitations. The latest of these is object-oriente
d one. Currently object-oriented approach for SCE is based on Line of Code (LOC), function points, functions and classes etc. Relatively less attention has been paid to the SCE in component-based software engineering (CBSE). So there is a pressing need to search parameters/variables that have a vital role for the SCE using CBSE which is taken up in this paper. This paper further looks at level of significance of all the parameters/variables thus searched. The time is being used as an independent variable because time is a parameter which is almost, all previous in one. Therefore this approach may be in a way an alternate of all previous approaches. Infact the underlying research ultimately may lead towards SCE of complex systems, using CBSE, in a scientific, systematic and comprehensive way.
