Database Grid Control

1, introduction of cloud computing using virtualization technology, users do not need to understand its specific operating mechanism, but simply through the network to connect to the cloud computing services to obtain their own services needed to achieve a greater degree of network resource sharing. Peng, a Chinese grid computing and cloud computing expert, defines cloud computing as follows: "Cloud computing tasks are distributed across a pool of computer-intensive resources, enabling applications to gain computing power, storage space and various software services as needed." Cloud computing is the further development of distributed computing, parallel processing and grid computing, which is based on the Internet.

In fact.   　　 Cloud computing technology is the combination of software SaaS, Grid computing, virtualization three concepts. Virtualization of Cloud Computing Technology (virtualization) virtualization is the virtualization of infrastructure (virtualization), the core of which is the combination of traditional mature cluster technology and partitioning technology. Cluster computing (Cluster comput ...

30 years of database development and formation of Oracle, IBM, Microsoft and other representative of the strong monopoly pattern, making the traditional domestic database not only untimely, coupled with the technology to follow the strategy, in the field of business processing tenacious fight, although the product continues to progress, market applications have also been to achieve a single point of breakthrough, But mostly in non-core applications. Despite the government's continued strong support, but in the monopoly barriers and open source software around the attack, in addition to the policy market, it is difficult to achieve a large-scale breakthrough, has not yet formed a benign cycle of enterprise development and government support for a mutually beneficial situation. ...

The internet has never been a peace, whether in the era of cloud computing or large data era, the Internet world is always undulating, before the advent of cloud computing, Oracle, MSSQL, MySQL, Postgres and other relational databases entrenched data kingdom most of the country, few can shake its position. But now the information is flying in the era changed this situation, with the rapid increase in data traffic ...

The application features of the power industry are very much in line with the service model and technology model of cloud computing. Cloud computing is the original dispersed resources gathered, and then to serve the form of the audience to achieve the group operation, intensive development, lean management, standardization of construction. The use of cloud computing, not only can realize the power industry data collection and sharing, and finally realize data mining, provide business intelligence BI, assist decision-making analysis, promote the coordinated development of production business, can also help grid companies to transform data into services, enhance service value, realize information neural network fusion. At home and abroad in the smart Grid cloud computing research and ...

The distributed computing technology proposed by Google makes it easy for developers to develop global application services, and cloud computing technology automates the management of communication, task allocation, and distributed storage among a large number of standardized (heterogeneous) computers. 　　The cloud comes from a decentralized, parallel operation, but better than the grid. Data computing cloud technology can be considered as a sub-set of grid technology, both of which are designed to hide the complexity of the system, so that users need to use it without knowing how the system works inside. The parties follow up with Google to promote cloud services, but the definition is different ...

July 15, according to foreign media reports, Oracle said in a statement in Thursday that it plans to release 78 patches in Tuesday to repair the security vulnerabilities of many of its software products, including 13 patches to repair Oracle's main database software vulnerabilities. Oracle will release a database patch involving many versions of the database, including 11g R1 and R2 as well as 10G R1 and R2. Two of these vulnerabilities can be exploited on the network by an attacker and do not require a logon certificate. There are three patches to repair Oracle's secure backup products. All three vulnerabilities can be exploited remotely without the need for ...

With the "gridding" fully open, Guangzhou city will arrange 20,000 grid staff to take "sweep the floor" and other practices on the grid some of the people, places, things, things, organizations and other information to be re-collected . In the face of this huge body of work, some grid members feel pressured. In fact, the collection of population information by public security departments, family planning departments and other government departments has long been going on and is quite complete. Since the data are not fully shared, the grassroots governments at the district, street and community levels have to "get on the go." For a long time, this "information island" has been criticized, is considered to be "one of the root causes of the phenomenon". Such as...
