There are several interfaces for relational database management systems (DBMS) in R, including Microsoft SQL Server, MicrosoftAccess, MySQL, Oracle, PostgreSQL, DB2, Sybase, Teradata, and SQLite. Some of these packages pass through the originalDatabase drivers to provide access, while others are accessed through ODBC or JDBC. Use R to access the memoryData stored in an external database is an effective means of analyzing large data sets, and can play

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:

This is the first part.

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
