Publikováno v: CLEI Electronic Journal, Vol 6, Iss 1 (2018)

The use of software agents as Database Management System components lead to database systems that may be configured and extended to support new requirements. We focus here with the self-tuning feature, which demands a somewhat intelligent behavior th

The actor model has been widely adopted in building stateful middle-tiers for large-scale interactive applications, where ACID transactions are useful to ensure application correctness. In this paper, we present Snapper, a new transaction library on

Sharding is the prevalent approach to breaking the trilemma of simultaneously achieving decentralization, security, and scalability in traditional blockchain systems, which are implemented as replicated state machines relying on atomic broadcast for

Towards a Technique for Extracting Relational Actors from Monolithic Applications

Autor: Marcos Antonio Vaz Salles, Marcus Poggi, Sérgio Lifschitz, Marcos Kalinowski, Rodrigo Laigner

Publikováno v: SBBD

Relational actors, or reactors for short, integrate the actor model with the relational data model, providing an abstraction for enabling actor-relational database systems. However, as a novel model of computation for databases, there is no extensive
