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

also have their own extensions and changes. 　　Key tasks (OLTP) and high-performance systems If we need databases to play a more important role in key business systems and want to achieve no-fault time, high availability, and cluster reliability (performance and data volume ), disaster replication, automatic report generation, and other goals, or the need to achieve extremely high-speed and low-latency (HPC, high-performance computing) results, we may need enterprise-level database features, but

IntroductionThe data warehouse architecture is a branch of the IT architecture. As the core role of data in enterprises increases, the data warehouse architecture becomes increasingly important. The data warehouse architecture seems complicated because of its wide selection of technologies. However, there is a set of stable ideas behind it. This is also a key point in the design of the data warehouse architecture, which contains changes in stability, the changes are stable.In general, the data w

ETL solution for high-performance business intelligence. It optimizes data merging, extraction, conversion, and dimension management, and provides a data warehouse suitable for enterprise reports and analysis. Vi. NCR NCR has announced the separation of teradata from its data warehouse business department, showing its determination to the business intelligence market. The dynamic data warehouse of teradata
