Orientando: Thiago Henrique da Silva Zanirato Orientador: Osmar Machado Assis­SP 2015 DEDICATÓRIA Dedico esse trabalho integralmente a meu pai, Paulo Vitor Zanirato, que nunca abortou os meus sonhos, pelo contrário, foi o primeiro patrocinador deles e o maior incentivador em todos os momentos. Foi o primeiro a me ensinar sobre me comprometer com as atividades que eu preciso executar em todas as áreas da minha vida. AGRADECIMENTOS Mesmo parecendo clichê, é a Deus minha gratidão. A graça Dele que me alcançou em cada um dos dias que eu investi na elaboração desse projeto. À meu amigo e irmão homem que não tive, Luis Gustavo Gonçalves Medeiras, com quem eu aprendi a ser profissional, que não me deixou desistir quando pensei em abortar o projeto, que investiu horas e horas me ajudando a aprender o bendito Java, sem você meu amigo, certamente seria tudo mais difícil, meus sinceros agradecimentos a ti. À minha mãe Rose, que ora por mim todos os dias pela manhã, que sempre apoiou e abençoou os meus planos. “Em Cristo estão escondidos todos os tesouros da sabedoria e da ciência.” Colossenses 2.3 RESUMO Atualmente, o processo de inscrição em eventos precisa ser rápido e bem dinâmico. Independentemente do segmento dos eventos, o usuário quer praticidade e segurança durante uma atividade como essa.
