Desenvolvimento de um aplicativo web para análise de dados: estudo de caso sobre o sentimento de evasão dos ingressantes do curso de Engenharia de Computação

Abstract

Data analysis is an extremely important process when it comes to evaluating data collected in order to obtain information that is useful in decision making. However, this process can often be complex and time-consuming, requiring the user to have advanced knowledge of logical and statistical techniques in order to obtain the most assertive results possible. Aiming to facilitate this process, this work describes the process of implementing functions in the R language (TEAM, 2022) through a web application developed in Shiny (SHINY, 2022), in order to provide tools that facilitate the process of data analysis, allowing the obtainment of descriptive statistics, creation of interactive graphs, cleaning, exploration and conversion of data, among other functionalities. To evaluate the purposes of the app, a case study was carried out on the dropout data of students of the Computer Engineering course at UFC Sobral. As a result, there is an easy-to-use application, proven after applying the System Sustainability Scale (SUS), and with a good performance when it comes to modifying, manipulating and obtaining relevant information from databases.
