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 (Parame

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
big data categories, such as Teradata, Oracle ExaData, Greenplum, IBM DPF ...3. Relative to data redundancy, I think the paradigm is mainly about data consistency. This is critical in transactional applications.4. Many of the features in a relational database are good, such as paradigms, consistency constraints, indexes, SQL optimizer based on statistics, not the big data platform, but because of the constraints on the CAP's quasi-side, which are dif
