EventChain: uma proposta de estilo arquitetural para sistemas orientados a cadeia de eventos na área financeira

Abstract

Architectural styles are important for engineering as they bridge the gap between requirements and implementation design. Its function is to express a set of features of a software architecture, aiming to provide a broad view of the communication between the components of the software architecture, facilitating reuse and reducing complexity. With the growth of the financial area, such companies employed different architectural styles in software development aiming to increase reusability, performance and security. The literature on the topic, however, lacks studies that investigate modern architectural styles that focus on the specific needs of software architectures for the development of applications in the financial area, such as scalability, high availability, consistency and integrity of information. Also, given the recent growth in this area, make developing new applications simple and robust. This dissertation, therefore, presents the EventChain, which is an architectural style oriented to the chain of events, which employs the use of asynchronous communication and Blockchain for the development of applications in the financial area. The proposed architectural style was evaluated in two ways. The first is the construction of a prototype in order to assess the feasibility and demonstrate its operation, and the second, the application of a technological acceptance questionnaire to assess the acceptance of the architectural style by industry professionals. The results obtained show that the proposed architectural style is a viable, functional implementation that meets the requirements of systems in the financial area. Finally, it is concluded that the architectural style represents a new approach with great potential to facilitate the development of new systems in the financial area, which addresses specific requirements and makes the implementation of new applications flexible.
