It is increasingly common for public and private organizations to deal with the challenges of data management in Big Data environments, tipycally characterized by high volume, great variety, fast generation velocity, in addition to intrinsic issues of data veracity and value. This context gave rise to NoSQL database technologies, with MongoDB as one of its prominent representatives. This paper aims to evaluate the performance of MongoDB in its cluster architecture against the standalone mode, with massive data from the National High School Exam (Enem), in addition to performing a brief interpretation of the results from the perspective of the educational domain. The initial results of query, update, and delete operations demonstrate a set of advantages and disadvantages of the experiments' architectures. The Information Technology (IT) professional's role in defining the scope of the database project for a more bold choice of the NoSQL architecture is highlighted in a cost-benefit perspective for organizations.

This paper presents the development process of a game that simulates the resolution of questions of the ENEM (Exame Nacional do Ensino Médio), which makes possible, in an attractive way to students, another possibility of exercising their knowledge throughout their preparation for the exam. In order to achieve this objective, a qualitative research was developed, which demonstrates, in its results, the interest of students in using a platform like the one created in this project. In addition to the research with students, studies were made in the field of education technology, investigating the impacts of this approach in learning. The game, called FlipENEM, was developed to run on an arcade machine in a way that is visually more attractive than the similar platforms already existent, which are also studied in this project. For the production of the software and assembly of the arcade machine, specific tools such as NetBeans, Java and MySQL Server were used. After the initial tests of the arcade with students in a campus, it was possible to observe its positive impacts, as reported by students in a research carried out later on. [ABSTRACT FROM AUTHOR]

This paper presents the process of usability of a game that simulates the resolution of questions of the ENEM (Exame Nacional do Ensino Médio). So, with this possible, in an attractive way to students, another possibility of exercising their knowledge throughout their preparation for the exam.

For the production of the software and the arcade machine, specific tools such as NetBeans, Java and MySQL Server were used. After the initial tests of the arcade with students in a campus, it was possible to observe its positive impacts about the attractivity. [ABSTRACT FROM AUTHOR]
