With the mounting demand of web applications, a number of issues allied to its quality have came in existence. In the meadow of web applications, it is very thorny to develop high quality web applications. A design pattern is a general repeatable solution to a generally stirring problem in software design. It should be noted that design pattern is not a finished product that can be directly transformed into source code. Rather design pattern is a depiction or template that describes how to find solution of a problem that can be used in many different situations. Past research has shown that design patterns greatly improved the execution speed of a software application. Design pattern are classified as creational design patterns, structural design pattern, behavioral design pattern, etc. MVC design pattern is very productive for architecting interactive software systems and web applications. This design pattern is partition-independent, because it is expressed in terms of an interactive application running in a single address space. We will design and analyze an algorithm by using MVC approach to improve the performance of web based application. The objective of our study will be to reduce one of the major object oriented features i.e. coupling between model and view segments of web based application. The implementation for the same will be done in by using .NET framework.

Motivation: Continuous glucose monitoring (CGM) systems are an essential part of novel technology in diabetes management and care. CGM studies have become increasingly popular among researchers, healthcare professionals, and people with diabetes due to the large amount of useful information that can be collected using CGM systems. The analysis of the data from these studies for research purposes, however, remains a challenge due to the characteristics and large volume of the data. Results: Currently, there are no publicly available interactive software applications that can perform statistical analyses and visualization of data from CGM studies. With the rapidly increasing popularity of CGM studies, such an application is becoming necessary for anyone who works with these large CGM datasets, in particular for those with little background in programming or statistics. CGMStatsAnalyser is a publicly available, user-friendly, web-based application, which can be used to interactively visualize, summarize, and statistically analyze voluminous and complex CGM datasets together with the subject characteristics with ease.

Cross Site Request Forgery

Today’s contemporary business world has incorporated Web Services and Web Applications in its core of operating cycle nowadays and security plays a major role in the amalgamation of such services and applications with the business needs worldwide. OWASP (Open Web Application Security Project) states that the effectiveness of security mechanisms in a Web Application can be estimated by evaluating the degree of vulnerability against any of the nominated top ten vulnerabilities, nominated by the OWASP. This paper sheds light on a number of existing tools that can be used to test for the CSRF vulnerability. The main objective of the research is to identify the available solutions to prevent CSRF attacks. By analyzing the techniques employed in each of the solutions, the optimal tool can be identified. Tests against the exploitation of the vulnerabilities were conducted after implementing the solutions into the web application to check the efficacy of each of the solutions. The research also proposes a combined solution that integrates the passing of an unpredictable token through a hidden field and validating it on the server side with the passing of token through URL.

Organization Model

Information system is one of the most important business supports in organizations. Web-based applications become an appropriate solution to overcome the dynamically changing environment among different units in an organization. Model-View-Controller (MVC) is a well-known design pattern in web-based application development due to the separation of an application into several parts, hence it is easy to reuse and maintain. However, such design pattern requires improvements since the information system handles business process choreography and integration between application. Therefore, modifying the interaction of object of class in a design pattern become a challenging problem. In this paper, an application framework based on Model-CollectionService-Controller-Presenter (MCCP) design pattern, which is a modification of an MVC, was proposed. The proposed framework allows multiple different applications to run and provides inter-application data exchange mechanisms to improve the data communication process between applications. Several performance comparisons with another popular web application framework are also presented.

Web-based applications has turn out to be very prevalent due to the ubiquity of web browsers to deliver service oriented application on-demand to diverse client over the Internet and cross site scripting (XSS) attack is a foremost security risk that has continuously ravage the web applications over the years. This paper critically examines the concept of XSS and some recent approaches for detecting and preventing XSS attacks in terms of architectural framework, algorithm used, solution location, and so on. The techniques were analysed and results showed that most of the available recognition and avoidance solutions to XSS attacks are more on the client end than the server end because of the peculiar nature of web application vulnerability and they also lack support for self-learning ability in order to detect new XSS attacks. Few researchers as cited in this paper inculcated the self-learning ability to detect and prevent XSS attacks in their design architecture using artificial neural networks and soft computing approach; a lot of improvement is still needed to effectively and efficiently handle the web application security menace as recommended.

Poultry Farming

Poultry farming has a very good business potential (Mohammad Khairu Islam, Mohammed Forhad Uddin, 2014) since they are fast growing animals meaning the business has potential to generate high return on investment under a short period of time. For example past days it took about four months for a chicken to become two kilograms, however these days a two kilogram chicken can be produced within 42 days (Hamra, 2010). Despite the fact that poultry farming has good business potential there are some obstacles which hinder the poultry business success such as lack of market linkage. Even with advancement of technology which has brought affordable smartphones to most of the livestock farmers, potential livestock information systems in Tanzania are used by very few livestock farmers and some are not used at all (Mussa et al., 2016). It is not that users do not need the system, nor the system does not show any potential for them, but depend on its usability and how well it suited to the user requirements based on their differences. Users of the system have a lot of differences including exposure to technology (Kalimullah & Sushmitha, 2017). It is now as more important than ever that web applications provide a good user experience which was once considered luxury or an added expenses (Juan, 2014; Ross, 2014). Web based platform for reliable market linkage has been developed with more focus on usability and user experience design. Eye tracking method combined with retrospective think aloud method and facial expression was used to test user experience of the developed web application. The result shows that users were emotionally happy when performing the second and the third tasks. But when performing the first task and the last task users were emotionally anxiety and disappointed.

Web-based systems and applications now deliver a complex array of functionality to a large number of diverse groups of users. As our dependence and reliance on the Web has increased dramatically over the years, their performance, reliability and quality have become paramount importance. As a result, the development of Web applications has become more complex and challenging than most of us think. In many ways, it is also different and more complex than traditional software development. But, currently, the development and maintenance of most Web applications is chaotic and far from satisfactory. To successfully build and maintain large, complex Web-based systems and applications, Web developers need to adopt a disciplined development process and a sound methodology. The emerging discipline of Web engineering advocates a holistic, disciplined approach to successful Web development. In this chapter, we articulate and raise awareness of the issues and considerations in large, complex Web application development, and introduce Web engineering as a way of managing complexity and diversity of large-scale Web development.

Web applications, which are computer programs ported to the Web, allow end-users to use various remote services and tools through their Web browsers. There are an enormous number of Web applications on the Web, and they are becoming the basic infrastructure of everyday life. In spite of the remarkable development of Web-based infrastructure, it is still difficult for end-users to compose new integrated tools of both existing Web applications and legacy local applications, such as spreadsheets, chart tools, and database. In this chapter, the authors propose a new framework where end-users can wrap remote Web applications into visual components, called pads, and functionally combine them together through drag-and-drop operations. The authors use, as the basis, a meme media architecture IntelligentPad that was proposed by the second author. In the IntelligentPad architecture, each visual component, called a pad, has slots as data I/O ports. By pasting a pad onto another pad, users can integrate their functionalities. The framework presented in this chapter allows users to visually create a wrapper pad for any Web application by defining HTML nodes within the Web application to work as slots. Examples of such a node include input-forms and text strings on Web pages. Users can directly manipulate both wrapped Web applications and wrapped local legacy tools on their desktop screen to define application linkages among them. Since no programming expertise is required to wrap Web applications or to functionally combine them together, end-users can build new integrated tools of both wrapped Web applications and local legacy applications.

Design pattern detection can provide useful insights to support software comprehension. Accurate and complete detection of pattern instances are extremely important to enable software usability improvements. However, existing design pattern detection approaches and tools suffer from the following problems: incomplete description of design pattern instances, inaccurate behavioral constraint checking, and inability to support novel design patterns. This paper presents a general framework to detect design patterns while solving these issues by combining static and dynamic analysis techniques. The framework has been instantiated for typical behavioral and creational patterns, such as the observer pattern, state pattern, strategy pattern, and singleton pattern to demonstrate the applicability. Based on the open-source process mining toolkit ProM, we have developed an integrated tool that supports the whole detection process for these patterns. We applied and evaluated the framework using software execution data containing around 1,000,000 method calls generated from eight synthetic software systems and three open-source software systems. The evaluation results show that our approach can guarantee a higher precision and recall than existing approaches and can distinguish state and strategy patterns that are indistinguishable by the state-of-the-art.
