Implementation of Content Management System and Website Redesign for JonFinn.com

January 2010 (has links)
abstract: The Jon Finn Group, a four-piece instrumental rock band based in Boston, MA, was in need of a website redesign, http://JonFinn.com. They required a website to showcase and sell their music and merchandise, promote upcoming performances, interact directly with their fans, integrate with social networking websites, and administer paid membership subscriptions via a content management system. Making this possible required an overhaul of the website, which was based almost entirely on static HTML files with limited capabilities for dynamic content updates. The band also requested a complete visual design overhaul compatible with traditional desktop computer web browsers, cell phone-based web browsers, and modern touch-based web browsing interfaces. WordPress, a free open-source content management system, was chosen to implement technologies to meet the Jon Finn Group's needs. Using WordPress required the development of a custom visual theme supported by various free and commercial plugins. WordPress and the supporting plugins required customization to extend functionality for becoming a revenue-generating platform through which paid membership subscriptions could be supported and administered. A survey instrument questioning end users on usability was used to measure the success of the website redesign and WordPress implementation. To evaluate the success of the redesign, analysis was performed on empirical data collected from web analytics and responses from the usability survey instrument as well as subjective data including stakeholder feedback and comments provided by the usability survey instrument respondents. Following the completion of the site redesign, it became clear that the site better engaged users than the previous site iteration and met end-users' usability expectations. Web analytics data indicated that users began spending more time on JonFinn.com and viewing more content than they had on the former website design. Usability survey data indicated that 95% of all tested functionality was found to be either "not difficult at all" or only "slightly difficult." Some comments and response data clearly indicated areas for improvement in the design and usability of the site. / Dissertation/Thesis / M.S.Tech Technology 2010

Um ambiente para análise de resultados de avaliações de acessibilidade e usabilidade na Web / An environment for analyzing results of assessments of accessibility and usability on the web

Leandro Agostini do Amaral 06 May 2014 (has links)
A Web apresenta um conteúdo extenso de informações disponibilizado a uma população diversificada de pessoas, as quais podem apresentar as mais diferentes habilidades e exigências. Dessa maneira, garantir a acessibilidade a todo usuário é uma tarefa difícil, mesmo existindo um conjunto extenso de recomendações disponibilizadas pelo World Wide Web Consortium (W3C). Assim, são propostas diferentes ferramentas para avaliação de acessibilidade, que contrapõem os artefatos às diretrizes com a finalidade de obter resultados automatizados, produzindo testes e gerando vários dados, como a localização do problema no código e as falhas especificadas. Para facilitar o processamento desses dados, mediante a disponibilização de uma linguagem comum, o W3C desenvolveu a Evaluation and Report Language (EARL). Dados os problemas acerca das dificuldades em se garantir a acessibilidade para os diferentes perfis de usuários e a necessidade da interpretação dos relatórios em EARL, como colaboração para a avaliação manual, indispensável no contexto de testes de acessibilidade, neste trabalho é proposto um apoio por meio de um Ambiente para Análise de Avaliações de Acessibilidade e Usabilidade na Web (A4U). A partir do estudo de caso realizado, pôde-se validar o ambiente A4U desenvolvido, o qual inclui relatórios de avaliações semiautomáticas, para que o desenvolvedor possa interpretá-los e prosseguir com a avaliação manual de acessibilidade e usabilidade. No âmbito do apoio desenvolvido, foram considerados os avanços em acessibilidade, usabilidade, a correlação entre os dois conceitos e a colaboração no desenvolvimento de uma ferramenta denominada AccessibilityUtil1, a qual se destina ser uma fonte de práticas de acessibilidade advindas de experiências de desenvolvedores, mediante colaboração em um ambiente Web, relacionando-as com as diretrizes de acessibilidade do W3C. A presente pesquisa contribuiu para a consolidação das questões de acessibilidade e usabilidade, a partir do desenvolvimento do A4U, que viabiliza a avaliação humana de acessibilidade e usabilidade, e a inserção de resultados de avaliações gerados por ferramentas semiautomáticas, conduzindo o avaliador a produzir melhorias em ambas as frentes / The Web has a large content of information available to a diverse population of people which may have the more different abilities and requirements. Thus, ensure accessibility to all users is a difficult task, even having an extensive set of recommendations provided by the World Wide Web Consortium (W3C). So, are proposed different tools for accessibility assessment that contrast the artifacts with guidelines in order to obtain automated results, producing tests and generating various data, such as the location of the problem in the code and the specified faults. To facilitate the processing of such data by providing a common language, the W3C developed the Evaluation and Report Language (EARL). Given the issues about the difficulties of ensuring accessibility to the different profiles of users and the necessity of interpreting the EARL reports, as collaboration for indispensable human review in the context of accessibility testing, this paper proposes a support through an Environment for Analyzing results of Assessments of Accessibility and Usability on the Web (A4U). From the case study conducted, it was possible to validate the A4U environment developed, which includes semiautomatic evaluating results, so that the developer can interpret them and proceed with the manual evaluation of accessibility and usability. Developed in support were considered advancements in accessibility, usability, the correlation between the two concepts and collaboration in the development of a tool called AccessibilityUtil, which is intended to be a source of accessibility practices arising from experiences of developers through collaboration a Web environment relating them to the W3C accessibility guidelines. This research contributed to the consolidation of the issues of accessibility and usability, from the development of A4U, which enables the human evaluation of accessibility and usability, and integration of evaluation results generated by semi-automatic tools, leading the reviewer to produce improvements in both fronts

"Avaliação de desempenho com algoritmos de escalonamento em clusters de servidores Web" / Performance Evaluation of scheduling algorithms in Web clusters

Caio Peres Sabo 13 June 2006 (has links)
O surgimento de novos serviços e aplicações baseados na Web tem provocado um aumento desenfreado na quantidade de usuários da World Wide Web que, por sua vez, se torna cada vez mais popular no mundo dos negócios. Sites de e-commerce, que demandam grande tráfego de requisições, têm adotado sistemas de servidores Web distribuídos, como a arquitetura Web Cluster. Isso se deve ao fato de enfrentarem frequentemente situações de sobrecarga, durante as quais podem deixar de atender requisições de transação (com grande probabilidade de gerar renda) por conta do aumento na demanda de requisições de navegação (geram renda apenas de forma indireta). A utilização ineficiente de recursos pode comprometer o desempenho do sistema e é nesse contexto que este trabalho se insere. Neste trabalho foi desenvolvido um modelo de Servidor Web para E-Commerce (SWE-C),validado por meio de um modelo de simulação e uma carga sintética gerada a partir de um modelo desenvolvido com os principais tipos de requisições que caracterizam um site de e-commerce. Foram realizadas simulações no sistema com diversas combinações de algoritmos de escalonamento e disciplinas de atendimentos para filas, dentre as quais de destaca uma nova disciplina que utiliza um mecanismo de prioridades orientado ao consumo de CPU proposto neste trabalho. O objetivo é aumentar o throughput de requisições de transação e melhorar os tempos de resposta em situações de sobrecarga. Uma avaliação de desempenho foi realizado e constatou-se que o mecanismo de prioridades proposto é adequado às necessidades de um site de e-commerce. / The appearance of new services and applications based on the web has causing a wild increase in the amount of users of the World Wide Web that becomes more popular in the business world. E-commerce sites that demand great request traffic has adopted a distributed web servers system, such as the Web Cluster. This occurs because this sites frequently are on overloaded situations, leaving to serve request transactions (with large probability of generate income) due to increasing demand of navigation requests (generates income only indirectly). The low resource utilization can compromise the system performance. This work is inserted in this context. In this master thesis has been developed a Web server model for E-Commerce (WSE-C). It is validated with a simulation model using a synthetic workload characterized with the main types of equest identified from e-commerce sites. Several simulations were accomplished in the system, combining the scheduling algorithms, the queue attendances disciplines and the use of a new priority mechanism oriented to the CPU utilization. The aim of this work is increase the request throughput and to obtain a better response time on overload situation. A performance evaluation was conducted and shown that priority mechanisms is adequate to a e-commerce site.
