SLOD: uma camada para sincronização de banco de dados

Abstract

Data synchronization is a procedure performed with the objective of maintaining identical or equivalently mapped information between two or more instances of a dataset. With technological advancements, the popularity of mobile devices, and the increasing number of applications that operate in offline mode or with limited connectivity, the need for effective synchronization mechanisms has become even more critical. Additionally, scalability, data consistency, and conflict resolution are frequent challenges in this context. This paper presents the design of a middleware capable of synchronizing different databases, ensuring data availability even in environments with intermittent connectivity, while also incorporating mechanisms to detect and resolve conflicts. Experimental results indicate that the proposed middleware is able to maintain eventual consistency across replicas and achieve synchronization times compatible with practical use.
