In the process of network programming, ADO (Activex Data Object) programming is often indispensable work, especially the development of e-commerce sites. Now that you're talking about ADO data objects, you can simply introduce ADO data objects and their functions. There are seven separate objects for ADO data objects, namely, connection objects (Connection), Recordset objects (recordsets), Domain objects (field), Command objects (commands), Parameter objects (Parameter), Attribute objects (prope

Microsoft's Parallel Data Warehouse (Parallel data Warehouse, abbreviated PDW) was released last year with SQL Server 2008 R2, designed to compete with Oracle Exadata and Teradata. PDW a true sense of the ability to mix workloads, users can extend data from multiple physical servers with a familiar SQL Server database engine. Parallel Data Warehouse is not a software system product, after purchase you cannot simply install it on the hardware. The mos

improvements. To support cloud services, MySQL is greatly enhanced by the new features of Gtids (Global trade identifiers). Gtids enables replication progress tracking and simplicity between master and slave servers, making it easier to recover from failures while providing flexible configuration and continuous management of multiple layers of replication. For 20,134 months, Oracle announced the release of the MySQL plugin for Hadoop. The plug-in enables replication from MySQL to Hadoop/hive/hd

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:

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
