Уstems соммунисдтвомъ оГтнв Асму Јune 1992. Vol. 1992 35、6号高度并行数据库系统正在开始取代传统的主机计算机来执行最大的数据库和交易处理任务。这些系统的成功驳斥了 1983 年一篇预测数据库机器消亡的论文 [3]。十年前，高度并行数据库机器的未来似乎很黯淡，即使对于它们最坚定的拥护者来说也是如此。大多数数据库机器研究都集中在专门的、通常是流行的硬件上，例如 CCD 存储器、气泡存储器、每磁道磁头磁盘和光盘。这些技术都没有兑现它们的承诺；因此，人们有一种感觉，传统的 CPU、电子 RAM 和旋转磁头磁盘将在未来的许多年里占据主导地位。当时，磁盘吞吐量预计将增加一倍，而处理器速度预计将增加更大的倍数。因此，批评者预测，除非找到 I/O 瓶颈的解决方案，否则多处理器系统将受到 I/O 限制。虽然这些关于硬件未来的预测相当准确，但批评者对并行数据库系统的整体未来的预测肯定是错误的。在过去的十年中，feradata、Tandem 和许多初创公司已经成功开发并销售了高度并行的机器。
Уstems соммунисдтвомъ оғтнв Асму Јune 1992. Vol. 35, No. 6 ighly parallel database systems are beginning to displace tra di ti onal main fra me computers for the la rg est database and tra nsa cti on processing tasks. The success of these systems refutes a 1983 paper predicting the demise of database machines [3]. Ten years ago the future of highly parallel database machines seemed gloomy, even to their staunchest advocates. Most database machine research had focused on specialized, often trendy, hardware such as CCD memories, bubble nemories, head-per-track disks, and optical disks. None of these technologies fulfilled their promises; so there was a sense that conventional CPUs, elec-tronic RAM, and rnoving-head magnetic disks would dominate the scene for many years to come. At that time, disk throughput was predicted to double while processor speeds were predicted to increase by much larger factors. Consequently, critics predicted that multiprocessor systems would son be I/O lirmited unless a solution to the I/O bottleneck was found.While these predictions were fairly accurate about the future of hardware, the critics were certainly wrong about the overall future of parallel database systems. Over the last decade'feradata, Tandem, and a host of startup companies have successfully developed and marketed highly parallel machines.
