摘要: This paper describes the architectures that can be used to build highly available database management systems. We describe these along two dimensions – process redundancy and data redundancy. Process refers of redundant processes take over in case a or node failure. Data maintenance multiple copies underlying data. believe models characterize most, if not all,
