The following paragraph is actually what I admire most: At the Computer History Museum in Mountain View, there was an exhibition that once software was tied to hardware, software was not an industry at the time, and IBM released programs that ran only on IBM hardware.

Oracle elastic cloud and data warehouse provide obvious advantages. First, a single vendor provides all the basic components: Oracle's one-stop approach helps simplify licensing, support, upgrade, and integration, all these transactions are handled by a single vendor. This may help prevent vendors from repeatedly pushing each other on technical issues. Configuration, upgrade, and integration use a single vendor approach makes it easier to simplify the contact and verification paths for these iss

With the development of enterprise business, there are more and more large data warehouses, and their scale is also expanding rapidly, increasing by three times every two years on average. Large Data Warehouses require scanning dozens, hundreds, or thousands of disks at the highest read speed. Therefore, enterprises often find that the larger the data warehouse, the slower the operation speed. Oracle Exadata database machine, also known as "database

-performance business intelligence system, we need to establish a rapid connection with data warehouses, operating systems, and data sources. In addition, when building clusters with high reliability, load balancing, and disaster backup functions, high-speed network interconnection is also an essential condition. Therefore, Oracle Exalytics provides the following network interfaces to support the above requirements: InfiniBand: Each Exalytics provides two InfiniBand ports with a four data rate (

The software industry we know now is actually the requirement of US enforcing anti-trust legislation for exclusive software and hardware vendors after software and hardware decoupling. HANA, coupled with databases, is controlled by a vendor, bringing us back to the initial software era.PS. Oracle Exadata is also a combination of software and hardware, but Oracle does not require the databa

the use of high-performance technologies (such as exadata, exalogic, supercluster, InfiniBand, etc.), we can not only increase cost efficiency, but also do better than ourselves. Sooner or later, you can close your data center and migrate everything to the oracle cloud. In this way, you will be completely liberated. "Our new private cloud is a natural extension of oracle cloud ."At present, you certainly do not want to close your data center. There

TechEd last month, customers and you provided testimonials to the value SAP HANA. Going forward, HANA would become the Next-generation platform that combines in-memory and cloud seamlessly and a "mobile-fi RST "approach to developing apps. Industry and technical influencers, customers, and the have validated our approach. On the other hand, let's take a look at what Oracle has announced–18 after SAP.

So my expectation for the Chinese market is that since Oracle has such a good PAAs and SaaS, if we work with our partners to build an ecosystem, it will be a win for all. ”Of course, for the Oracle company, in the era of cloud technology also has "unchanged" insistence.
