摘要: A database system comprises a plurality of replicated databases and provisioning such that when record needs to be updated, the selects one as selected with remaining being non-selected databases. The transmits each update data for updating pointer identifies database. is placed in memory queue while written into field updated then transmit ready-to-commit acknowledgment system. reset indicating has been selected. updates sends commit confirming update. instructs clear field.
