Experts from Chinese academic schools are full of praise for new DB2 9 Products

The current db2 tutorial is: domestic academic experts are full of praise for the new DB2 9 product.

Academician of Ni guangnan Chinese Engineering Institute:Today, IBM combines hierarchical databases and relational databases to provide powerful functions. I think IBM is worth learning in this regard. For example, we mentioned the software technology problems in China in the previous section, and now we are learning about IBM's innovation and transformation. In addition, the support for database management like IBM and the support for so many middleware except DB2 are worth our research and application. If we want to transform something, we don't know how to transform it. What we see is not software or middleware, but animation and online games. I think we must stick to innovation and continuous innovation. We need to learn from IBM's spirit of continuous innovation.

Zhou aoying, professor of computer science at Fudan University:I think today's DB2 9 is a revolutionary product. If DB2 9 is widely used in the future, I think it may bring about a change in the overall concept. We are going to go to a real world. How can we do this? We can say that the national and local taxes we mentioned just now have repeated content. What should we do? The relationship between you and me is changed. What should we do if there are continuous updates? I think from the perspective of our research, we will bring about some revolutionary changes in the database information system from the industry perspective. I hope to see that day.

Dean of computer department, Fudan University, guoning:Now we can see that DB2 9 is a pretty ugly line. After reading the introduction, I learned a lot about the development history of DB2. In addition, after reading the technical introduction and demonstration, I felt that in the past, the relationship was actually expressed together with the object. In fact, there are many similarities between the hierarchical model and the object. However, the processing methods are quite different. We can see that the changes in levels and relationships, and mutual changes, will have a lot of inspiration for modeling, including for students. So I also made a suggestion yesterday. When I talked about databases in the past, I hoped to have some information and it was difficult to find some corresponding sources immediately. We also want to give students Database courses. We also hope that we will be very interested in such materials as DB2 9. I think the same is true for students. The biggest feature of our development department is that our products are oriented to customers. For colleges and universities, teachers and students are a type of customers. Our teachers will pass on new knowledge to students, and of course some new technologies. Of course, it is also very important for us to study our own databases.

Researcher at Zhou longyi Chinese Emy of sciences:I started my database research in 1976. At the beginning, they were all hierarchical. Why are they all hierarchical? Because we need to describe these events in the face of a real event, the most intuitive one is the tree. Why is IMS doing well and becoming relational? Because the user does not know where the information is lost, and so on, the relational database can make the content very simple. The theory is very clear, so you can rest assured that if there is any problem, no information will be lost or added. Therefore, relational world experts have been studying for ten years before they can be used. However, in the face of events, if we are still very complicated, tree or mesh things will continue to exist. As a result, the tree structure in the Silicon Valley era is simplified. What should I do? The relational expression is very troublesome, and it is still necessary to solve the problem. Now IBM releases DB2 9, which is a good thing. If it is fashionable, it leads the database trend.

Professor at the Graduate School of the Chinese Emy of sciences:IBM's middleware Products have very potential practical value for China. I suggest that IBM study that China's society is not the same as that in the United States, Japan, and so on. It is informatization Without industrialization, and the complexity will be much higher. Therefore, do not include us experience in China. In addition, I think that the Technical Innovation of IBM products must be a leader in application. If there is no industrialized informatization construction at all, this is a big topic. If this topic is well resolved, I think all of us in China will thank you, only in this way can we be better applied in China and truly promote information construction.

Tang Shiwei, professor of computer science at Peking University:First of all, I think that IBM has made great contributions to the database field and is not alternative to other general enterprises. What's more, today will be the crystallization of 40 years of innovation and review the glorious history. I think this is very important. Only by understanding the glorious history of DB2 can we continue to work hard. I recall one thing in a few years. A professor from IBM introduced DB2 to Peking University. He introduced that IBM's databases have been doing well over the past few years. So far, after 40 years, DB2 9 is about to be released. For large companies like IBM, I think these achievements are milestones. I wish IBM a better chance to create greater glory.

Wang Jianmin, professor at the School of software, Tsinghua University:There are two themes today: innovation and a new era. There are two sentences in China: one is to say that a great event in the world will be combined for a long time. IBM just verified this sentence. There is also an old saying in China that hewei is expensive. IBM has made great contributions to the database. It is such an enterprise. While talking about itself today, I feel that I have enjoyed the general demeanor, I would like to express my respect for a very inclusive attitude towards our peers in the industry. Finally, I have been working as an enterprise information service for many years. So I am lucky to meet experts today. I think Chinese enterprise information is facing great challenges. That is to say, when China's infrastructure is generally perfect, effective management of enterprise information is a huge challenge facing China. I think IBM should have this capability, we have the confidence to push China's informatization to another new realm.

Associate Professor of database laboratory, School of information science, Beijing University, Gao Jun:I have previously done some XML-related research, researched some of IBM's new products, and learned that IBM wants to build XML product processing on relation DB. Today I saw a release of IBM DB2 9, we know that IBM now supports integrating relational database products into XML data products. I think this combination will greatly reduce the workload of programmers and improve XML data management, including XML publishing from relational databases to XML, and XML data storage to relational databases. This accelerates application development and improves the efficiency of XML data management. Through this demonstration, I know that viper 9 can easily manage XML and support application development faster and better.

Previously, in XML management research, I Know How IBM is working on combining relational database products with XML data products. Today's release of DB2 9 has proved that IBM has officially launched such a product. I think the launch of such products will facilitate XML data management and improve the development efficiency of application systems.
