Data Coherence

"Tenkine Server channel August 12 News" At the first Huawei Global Financial Forum held recently, Huawei has been highly appraised in the data center's comprehensive disaster preparedness network delivery solution. 　　Data center has become an important infrastructure to ensure the normal work of the financial information system, how to ensure the continuous and reliable operation of the data center, how to deal with and effectively resolve the risk caused by the data concentration, has become an important issue of concern in the industry. Financial data center development and disaster preparedness demand at present, most enterprises in the financial industry have established data centers, and achieved a large concentration of data, all ...

In the user research work, how makes own data and the conclusion to be more persuasive, is very important question. Recently accumulated their own use of research reliability and validity of the notes collated, listed in the text, I hope to help you. The quality of the investigation depends on the reliability and validity of the investigation. Reliability mainly refers to the consistency and stability of the measurement results. That is to say that the conclusions and data reflect the user's most realistic and stable idea. When users answer questions, they tend to be influenced by the environment, time and local emotions, and the idea that they are not true is that there will be random errors. Reliability is the measure of this ...

Employment is better than the first quarter, Renmin University of China Institute of Labor and Human Resources The latest quarterly analysis of the report said 2009 ...

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 distributed features of the NoSQL database ...

Traditional data centers are built around a single application or multiple islands of application, and the maintenance of proprietary technology and applications takes up a lot of innovative resources, and only a few resources can be used to create business value. The emergence of cloud computing has changed this situation, providing companies with more opportunities to create greater business value. The good virtualization features of cloud computing can be flexibly deployed in accordance with the needs of the enterprise business, while the design pattern of cloud computing can be rapidly optimized and innovated, thus greatly reducing it complexity, helping the enterprise to effectively improve it cost structure, and meet the ever-increasing ...

In the area of mobile device user experience design, subtle and exquisite animation has become a very important design element. Adding animations to any object is not easy, and it needs to be seen how objects move in time and space in the real world, requiring designers to be attentive to detail and patient. The right animations provide clear information and a visually interesting experience, while too much animation can lead to a bad user experience. So how do animations on mobile devices design? Johnston and Thomas were published in their 1981 edition of the Illusion.

The fastest way to store a computer system is the ram traditionally used primarily as memory. As the access performance of the hard drive has deteriorated over the years, and the cost of RAM has been decreasing, many researchers have been exploring how to replace the hard disk with memory in recent years. As early as the 1980, David DeWitt and Garcia-molina and so on published a main memory database paper. Steven Robbins's article points out that the Turing Prize winner, Jim Gray, is more explicit about the idea that "memory will be a hard drive and the hard drive will become a tape."

When it comes to making new products or new projects, it's always a misery to get enough of the original demand, and behind closed doors is clearly not the best way to bring a strong individualism to the product. In fact, there are new projects to be launched, at least there will always be a vision, according to this to dig up the demand is slightly easier, the most afraid of that kind of no direction, everything is experimental nature, need to do to find the direction of the project, the beginning of the time will be run without purpose. Without a clear list of requirements functions can not be product development or project implementation, then a ...
