module such as the Software Development Kit (SDK) receives a report request, the request is first processed by the Query planning layer.The upper part of the query planning layer is the query Framework (QFW). QFW checks the report request and determines whether it contains one or more requests, and the query should be processed here. OLAP queries for SAPBW, such as Oracle Essbase and ibmcubing Services-type data sources, go to OLAP query planner. Relational queries for IBM DB2, Oracle,

value of Parallel Computing in computer clusters. In fact, this feature was studied by the database management system research community in the 1980 s, and multiple prototypes were proposed, such as gamma, Bubba, and grace. Commercial exploitation of these ideas in the system was at the end of 1980s, such as teradata. To sum up, in the past 20 years, a high-performance, commercial SQL engine (with structure descriptions and indexes) has emerged for

Recently, I tried to use sqlserver2005 integrate services to extract data from heterogeneous databases and use the ODBC-connected teradata as the data source. Refer to the "SQL Server 2005 database development details" (Electronic Industry Press Hu baijing Yao Qiao Mei) P361-363, the operation steps in SSIs are as follows: (1) Right-click the Connection Manager and choose create connection> ODBC to create an ODBC connection. (2) create a dataread

OLAP.3. Data imported from other external DW data sources through the ETL tool.All of the current SQL on Hadoop products are actually suitable in one or some specific areas, without the silver bullet. It is unrealistic at this stage to satisfy almost all enterprise-class applications like Oracle/teradata. So every SQL on Hadoop product is trying to satisfy the characteristics of a particular class of applications.Typical requirements:1, interactive q
