Chenyun: DB2 9 has 3 points to help the enterprise _DB2

The DB2 tutorial being looked at is: Chenyun: DB2 9 has 3 points to help the enterprise.

Chenyun received a Ph. D. In 2001 and received a postdoctoral degree in information and communication engineering from Peking University in 2005. During the work of China Mobile, it has creatively put forward the theory of hierarchical data Warehouse in the world, presided over the design and construction of China Mobile Data Warehouse system, invested billions of yuan before and after, built the current international maximum capacity of data Warehouse system (up to June 2006 to reach 1416TB storage capacity). In China, the first systematic introduction of various business applications of Data Warehouse (Report/Index/olap/data Mining, etc.), the first time on the basis of metadata XML, a comparative system of data Warehouse data quality management system was established. Through his hosting and design of the largest data warehouse system, to fill the domestic data warehouse in the field of technology and application of a lot of gaps, led to a number of domestic data warehouse field manufacturers and research forces, the domestic data warehouse industry has played a positive role in promoting the development.
In response to IBM's launch of the DB2 9 database new product, Chenyun published his views:

"IBM DB2 9 I think there are a lot of help to end users from three aspects,

first oneis the enhancement of XML technology, this function can help users to integrate a variety of different data sources, then through this integration of XML technology to help users more flexible to apply new data sources, complex data sources, which should be said to the entire database technology is a great upgrade.

a secondAspect is its compression technology. Because now the information society involves more content, the capacity of the data will become more and more inflated, so from this point of view, it should be said that through the use of compressed technology, effectively control the cost of storage, especially the large amount of data, the amount of data, this aspect of the user has a great help.

a thirdThe main value of DB2 in this 9 release is in security control, and there are some enhancements to the data in terms of access control. This is a great help to the actual use. Because in the entire application process, the data involves a lot of sensitive information.

From the user's point of view, in terms of application, he wants fixed users to see only fixed information. Traditional angle, we can only in the application level control, inevitably some mistakes, now from the DB2 9 version angle, in the database level control, the whole system development, including security control ability, has a great upgrade.

In short, from the point of view of the user, I think the DB2 9 version of the massive data of this application, large information processing, especially in the data warehouse and other applications in this area has a great help, many new features and functions, practical applications have a great help. So I would like to stand on the user's point of view, particularly practical, welcome DB2 aspects can continue to introduce a new version, can continue to solve new problems, improve the application and development capabilities, for users to develop more and better software.
