DBValTooi : uma ferramenta para apoiar o teste e a validaçao de projeto de banco de dados relacional

Orientador : Márcio Eduardo Delamaro e Edmundo Sérgio SpotoDissertaçao (mestrado) - Universidade Federal do ParanáResumo: A capacidade de armazenar, disponibilizar e proteger uma grande quantidade de dados confere aos bancos de dados papel de grande importância na maioria das modernas organizações, sejam elas grandes ou pequenas. E essencial que os sistemas de banco de dados funcionem corretamente e apresentem desempenho aceitável. Diante da importância da integridade e da consistência das informações a serem armazenadas nos sistemas de banco de dados, técnicas específicas para testar as bases de dados, principalmente antes de serem povoadas, respondem a uma necessidade muitas vezes vital. Nesse sentido, este trabalho apresenta um modelo de processo de validação de projeto, que tem como objetivo principal aumentar a qualidade e a confiabilidade dos projetos de banco de dados. A Ferramenta DBValTool, que pode ser utilizada em várias etapas do modelo proposto, foi desenvolvida para fornecer o apoio necessário ao teste de bases de dados, buscando proporcionar um aumento da qualidade e uma redução de tempo e de custo durante a atividade de teste. O uso do modelo proposto e da Ferramenta DBValTool, em estudos de casos realizados, apresentou, como se esperava inicialmente, contribuições ao processo de teste e de validação do projeto.Abstract: The capacity to store, to make available and to protect a large amount of data gives the database a role of great importance in most modern organizations. It is essential that the database system properly works and shows an acceptable performance. Considering the importance of both integrity and consistency of the information to be stored into the database systems, specific techniques to test the databases, mainly before being filled, are essentials. This study shows a process model for design validation that aims at enhancing both the quality and reliance of the database projects. The DBValTool, which can be used in several stages of the suggested model, was developed to give the necessary support to the databases test, trying to improve the quality and reduce both the time and cost during the test activity. The use of the suggested model and the DBValTool in case studies performed, showed, contributions to the validation and test process of the database design

University Open to Older People: factors associated with the use of information and communication technologies

Objective: to identify the factors associated with the use of information and communication technologies by older students at a University Open to Older People. Methods: this was an analytical, cross-sectional study with 102 participants of both sexes. This was an analytical, cross-sectional study with 102 participants of both sexes. The study collected data from older people via web to characterize the socioeconomic and technological profile through a self-completed questionnaire. Results: the findings of the present study revealed the existence of a significant association between the frequency in higher education and the use of notebook (p=0.021) and smart TV (p=0.031). Additionally, the analysis observed an association between the monthly family income higher than four minimum wages and the use of tablet (p=0.026), smart TV (p=0.006) and printer (p=0.002) by the sample participants. Conclusion: education level and socioeconomic status were some intervening factors in the use of technologies by the older individuals enrolled in a University Open to Older People. Contributions to practice: the study provides information on the profile of older students regarding the main factors associated with the use of information technologies. With this, activities that enable greater integration and motivation of this population can be programmed and offered
