Systems Integration Using Web Services, REST and SOAP: A Practical Report

In academic environments, it also happens. However, academic environments may be even more heterogeneous as there are many specialized activities, such as: restaurant, library, academic processes, administrative processes and computer network services, such as email and network authentication. To maintain the data consistency throughout the systems, all the systems must be integrated. This integration was carried out at the Federal University of Lavras, using Simple Object Access Protocol (SOAP) as communication protocol. The development of a new system (mobile application), it was noticed that SOAP is very CPU-intensive and slow, as mobile devices have constraints such as internet and processing. Thus, a REST-JSON layer to integrate mobile application and the integration architecture was developed, benefiting from all the resources the integration architecture had. By using this new layer, the offer of functions from the integration architecture was also expanded to REST, attending to other applications without having to make big changes in the code. It was measured that the REST-JSON layer consumes around 73% less data than SOAP. The REST-JSON layer was released, attending to about 5600 installations of the application that requests the integration around 54000 times a day.

Este computador foi desenvolvido no Reino Unido pela Fundação Raspberry Pi. O principal objetivo foi &quot;colocar o poder da computação na mão da população&quot; (RASPBERRY PI, 2012). Pelo baixo custo, é possível vislumbrar a promoção de atividades de ensino em informática nas escolas, levando à inclusão e ao empoderamento social. Em atividades práticas de laboratório, muitas vezes são necessários computadores com permissão de administrador e de fácil acesso. Em disciplinas como Big Data e Inteligência Artificial, o desenvolvimento e aplicação de modelos inteligentes e Internet das Coisas pode ser facilitado por meio da mobilidade das placas de Raspberry, fomentando entre os alunos a pesquisa e a extensão integrados ao ensino. Além da coleta de dados, o ensino de processamento em larga escala com clusters pode ser feito por meio dos Raspberries (NUGROHO S e WIDIYANTO A, 2020), em conjunto com ferramentas como o Apache Spark (MENG X, et al., 2016) ou o Apache Hadoop (QURESHI B, et al., 2016). Em resumo, o Raspberry pode trazer vantagens e experiências diversas ao aprendizado dos estudantes (ZHONG X e LIANG Y, 2016).

Data Mining applied on Web Robots Detection: A Systematic Mapping

The number of web pages is increasing and so is the amount of published content (news, tutorials, images, videos) provided by them. Search engines use web robots to index web contents and to offer better results to their users. However, web robots have also been used for exploiting vulnerabilities in web pages. Thus, monitoring and detecting web robots’ accesses is important in order to keep the web server as safe as possible. Data Mining methods have been applied to web server logs (used as data source) in order to detect web robots. Then, the main objective of this work was to observe evidences of definition or use of web robots detection by analyzing web server-side logs using Data Mining methods. Thus, we conducted a systematic Literature mapping, analyzing papers published between 2013 and 2020. In the systematic mapping, we analyzed 34 studies and they allowed us to better understand the area of web robots d...

In the Primary Selection stage of an SLR, the selection of studies is usually performed manually by reading title, abstract and keywords of each study. In the last years, the number of published scientific studies has grown increasing the effort to perform this sort of reviews. In this paper, we proposed strategies to detect non-papers and duplicated references in results exported by search engines, and strategies to rank the references in decreasing order of importance for an SLR, regarding the terms in the search string. These strategies are based on Information Retrieval techniques. We implemented the strategies and carried out an experimental evaluation of their applicability using two real datasets. As results, the strategy to detect non-papers presented 100% of precision and 50% of recall; the strategy to detect duplicates detected mo...

In general, a SLR has three phases, and the first one is the Primary Selection in which the selection of studies is usually performed manually reading title, abstract and keywords of each study. The number of published scientific studies has grown, increasing effort in carrying out this review. In this paper, we proposed two strategies to rank studies in decreasing order of importance, for a SLR, regarding the terms in the search string. These strategies are based on the Information Retrieval technique Vector Model. We implemented those strategies and conducted a case study to evaluate their applicability. As results, the second strategy presents 50% of precision on a recall of 80%. Among the contributions of this study, two strategies to rank relevant documents in a SLR, regarding the search string, were proposed and analyzed.

As a result, some contemporary technologies have been proposed for software development to improve maintainability, such as feature-oriented and aspectoriented programming. Metrics are used to quantify the quality of systems developed in these technologies. Recently, contemporary metrics have been proposed or adapted from existing ones to evaluate specific issues of these contemporary technologies. This paper presents results of applying a systematic literature review to identify contemporary metrics associated with software maintainability and proposed for the featureoriented and aspect-oriented technologies. Initially, we identify 672 published works and, after the primary selection, these quantity was reduced to 11 papers. These papers account for 33 and 78 contemporary metrics for feature-oriented and aspectoriented technologies, respectively. The main contributions of this paper are (i) the list of metrics and measurable properties studies for feature-oriented and aspect-oriented programming, (ii) elaboration of a unified catalog of metrics applicable for both technologies, and (iii) identification of their main references.

Academic environments (AE) are even more complex than corporate environments because they have several IS to help manage different aspects, such as restaurant and library, which need to have consistent data to work properly. Therefore, it is necessary to encounter a form to develop an integration among them and share common, trustworthy data. We present a case study on SOA-based architecture for IS integration within AE to keep data consistent through the systems, to monitor the communication, and to make the integration safe and manageable. We applied the proposal, and the results show that we can integrate, monitor, and manage different software systems and network services and permissions. The main contribution is a useful integration architecture for AE that must share trustworthy data among several, heterogeneous IS and network...

In this sense, this paper presents an evolution of EduSE Portal aiming to store and manage these initiatives as learning objects (LOs) and experience reports in a repository, as well as coordinate the roles of stakeholders based on reuse processes. In the LOs repository, the SE researcher provides his/her initiative and a protocol that will guide the professor in LOs application in classroom. Thus, professors can search and retrieve LOs and researchers can get the community feedback. In the experience reports repository, researchers and professors perform the integration of their experiences and this exchange can improve both LOs application and evolution. An initial usability study is discussed, evaluating the infrastructure as a whole.
