“…The reduction in lignin content via alkaline pre-treatment indicates the rupture of the lignocellulosic complex (KIM, et al, 2016). Similar results for delignification of rice husk and straw were presented by other authors (AZEVEDO et al, 2016, TAKANO & HOSHINO, 2018. The highest reduction for lignin content in PCR samples is due to the presence of layers of silica, constituting a kind of shield that prevents the action of alkali (MARIN et al, 2015).…”

Over post-harvest steps of rice, from pre-cleaning to processing, a large amount of by-product is generated. Some of these by-products, due to their high starch and fiber content can be used in ethanol production. The objective was to evaluate the effect of enzymatic hydrolysis conditions on the production of reducing sugars, from pre-cleaning residue and type III paddy rice, as well as the effect of the pre-treatment of its fibers, targeting the use of these residues in ethanol fuel production. The proximate analysis was performed, followed by the pre-treatment of samples. Enzymatic hydrolysis was conducted in two ways: using one enzyme at a time or applying them simultaneously. The starch content was 41.18 and 53.41%; the fibers were 30.44 and 23.39%, of which 6.53 and 4.41% were lignin, for the pre-cleaning residue and paddy rice, respectively. Alkaline pre-treatment reduce lignin content by 47.94 and 18.23% for the pre-cleaning residue and type III paddy rice, respectively. Hydrolysis efficiency was 22.61 and 15.32% for the cellulase enzyme, and 82.18 and 87.07% for the amylolytic enzymes in the pre-cleaning residue and type III paddy rice, respectively. The hydrolysis with the separated enzymes presented higher reducing sugar yields. Therefore, the pre-cleaning residue and type III paddy rice can be used for ethanol production by its enzymatic hydrolysis, aiming to add value and to increase the sustainability of the rice production chain.

“…Sendo assim, é formado uma base de dados sólida com uma grande quantidade de dados centralizados armazenada, essa base é voltada para tomada de decisões (Kimball, 1996;Inmon, 1996ª;Rezende et al, 2003). O data marts é uma estrutura de dados auxiliares que consegue armazenar de forma otimizada apenas as informações necessárias aos usuários, resultando em consultas mais rápidas e mais direcionadas de acordo com a necessidade dos departamentos de uma organização Inmon (1996 b).…”

“…Desta maneira, com o uso das técnicas do data mining é possível extrair informações úteis que estão localizadas nos dados (Fayyad et al, 1996b). O préprocessamento dos dados, extração dos padrões e o pós-processamento compõem as três principais etapas da mineração de dados (Rezende et al, 2003).…”

Competitiveness in the business market is becoming increasingly strong due to the constant advancement of technology, which makes it necessary to search for positive results and the systematization of processes, in such a situation, new opportunities arise in which it is possible to extract the maximum potential of all data obtained in a systemic way, applying the concepts of data analysis based on business intelligence. This research aims to present the main methodologies and tools used to perform in-depth data analysis, exploring and defining the use of the concepts of data warehouse, data marts, OLAP, data mining, ETL, business analytics and also business intelligence tools. With the aim of demonstrating the importance of such concepts as a digital competence to IT professionals and also to support decision-making in organizations, so that an understanding on the aforementioned subject becomes possible. You will also be able to understand how data analysis along with all the other concepts mentioned impact on the life of a company, helping in the definition of strategies, the assembly of plans and especially in decision making.
