2. In database administration, a replication topology where one master database propagates changes to multiple slave or replica databases
Single-source replication is simpler to manage than multi-source replication but offers less fault tolerance.
A replicação de fonte única é mais simples de gerenciar do que a replicação de múltiplas fontes, mas oferece menor tolerância a falhas.
This is a technical term primarily used in database administration and IT infrastructure contexts. Both Brazil and Portugal use the same terminology in professional settings. The shift from 'mestre-escravo' (master-slave) to 'primária-réplica' (primary-replica) reflects global inclusive language movements in the tech industry.
