It is too early to give a full and objective assessment of this latest mainstream database product, and it also needs to be expressed in practice in terms of performance. However, for the meaning of this product, the industry is still in the discussion and analysis, which is unusual. The focus of the discussion focused on DB2 9’s largest new feature - XML Direct Support. At the conference of DB2 9, IBM academician Zheng Miaqin said that it is no exaggeration to rename DB3 to such a large technological span as DB2 9. However, in a list of almost a dozen new DB2 9 features, most of them are just general technical improvements that deserve to be highly appreciated by Academician Yuen. Only XML directly supports this. People’s question is, what is the significance of such a new function? In the end is a commercial hype stunt, or general
