TPCH is a toolkit provided by the TPC (Transaction processing performance Council) organization. Used for OLAP testing to assess the performance of decision support systems (DSS) in Business Analytics. It includes a suite of business-oriented AD-HOC queries and concurrent data modifications, emphasizing the testing of databases, platforms, and I/O performance, and the ability to query.Official website: http://www.tpc.org/tpchDownload Address: http://www.tpc.org/tpch/spec/tpch_2_14_3.tgz or Http:

will be divided into three parts to answer each of these questions, the first part of the introduction of basic knowledge including database configuration and operations, the second part of the database integration modeling, the third part of the performance optimization. This is the first part.

time. Unlike some early systems, such as Teradata, which must be deployed on proprietary hardware, recently developed systems such as Aster and Vertica can be deployed on ordinary commercial machines, which can be called quasi cloud systems. The main drawback of parallel database systems is that there is no good elasticity, which is advantageous to small and medium enterprises and start-ups. When we design and optimize the parallel database, we thin

believes that if actuaries have more timely and richer data, the accuracy of their predictions will be improved. As a result, the actuarial and IT departments work closely together to create an actuarial trend system (actuarial Trend System,ats) based on an enterprise-wide data Warehouse, using the technology of the Teradata Information Company (Intel). The Data Warehouse stores information on policyholders and medical and pharmaceutical claims from
