Article - Main Track Systems Integration Using Web Services, REST and SOAP: A Practical Report Author: GARCIA, C. M.; ABÍLIO, R. Abstract: In companies environments, it is normal to exist several systems to ease daily activities. 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 in the Federal University of Lavras by using Simples 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. Keywords: Service-Oriented Architecture, Information Systems Integration, Web Services, JSON, SOAP Referência completa: Garcia, C.
