Implementação de processamento assíncrono em transacções bancárias para melhorar a disponibilidade do serviço de internet banking: caso de estudo - sistema de internet banking do banco Nedbank Moçambique

Abstract

In the context of the current dynamic financial environment, availability is a crucial aspect for the success of banking services, especially in the realm of internet banking. This work proposes an innovative approach to enhance the availability of the internet banking system, focusing on the implementation of asynchronous transaction processing technology. The adopted methodology involved a thorough analysis of available resources, with emphasis on literature review and interaction with collaborators from Nedbank Moçambique. Significant challenges in the internet banking system, particularly in the area of availability, were identified, serving as a starting point for the formulation of solutions. The development of the prototype was guided by the study of types and forms of asynchronous processing implementation, based on the architecture model presented in Chapter IV. An incremental migration approach was chosen to ensure minimal impact on normal operations and facilitate integration with the existing system. The practical implementation of asynchronous processing overcame the identified challenges, resulting in a more resilient internet banking system with increased availability. At the end of the development, all requirements, including desirable ones, were fully implemented, culminating in a fully functional system that is already in operation at Nedbank Moçambique. This study not only presents an effective solution to enhance the availability of the internet banking system but also highlights the relevance and effectiveness of asynchronous transaction processing technology in this context. The achieved results not only met the established objectives but also provided valuable insights into the practical applicability of this innovative approach in the banking sector.
