Oracle Database Recovery Techniques

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the NoSQL database distributed special ...

When 2010 is about to end, the new private and hybrid cloud systems are considered by everyone as the way forward. Now, as time flies, 2011 is over, and many of the past predictions have come true. 2011 can be said to be a veritable "cloud computing" year. In the past year, thousands of cloud architectures began to be built and deployed, and are widely used in a variety of industries. More and more IT vendors at one point has maintained a consistent idea that they all believe that the next year, cloud computing IT equipment procurement song ...

End-to-end encryption policies must take into account everything from input to output and storage. Encryption technology is divided into five categories: file-level or folder-level encryption, volume or partition encryption, media-level encryption, field-level encryption and communication content encryption. They can be defined further by the encryption key storage mechanism. Let's take a look at the grim forecast: According to the US Privacy information exchange, One-third of the U.S. people will encounter the loss or leakage of personally identifiable information from companies that store data electronically this year. Whether that number is not exactly right, anyway the public knows the data leaks ...

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 ...

Today, the De-duplication product is more than just HP, EMC (Avamar and Data Domain), Asigra, Symantec, Atempo and CommVault, so let's take a look at the following duplicate data deletion products that you may not have contacted: 1. The basic premise of the phased data reduction of NextGen Storage NexGen is that the current data deduplication tool is for the backup process, but in the future ...
