Database Comparisons

The idea of using the Internet to provide IT capabilities as a service is relatively new, but recently people have reached a climax in their attention. Infoq has also published several articles, such as "Introduction to Virtualization" and an article on virtualization security, but there is still a lack of comparisons between different cloud providers. This article compares three cloud computing providers, which provide a server-centric solution, starting with a description of how to start three cloud computing services and then comparing the performance, price, and availability of services to three service providers. ...

In the siege of large manufacturers such as Oracle, IBM and Microsoft, domestic database makers are still struggling to survive. This is an undeniable fact that the database market is close to saturation, especially in the face of the relationship between the transaction database field, foreign manufacturers start early, rich in resources, and also continue to encroach on the market segments, has formed a huge advantage. Faced with this situation, the South's general CTO Vounie that the domestic database manufacturers have missed the best time, should not take their own short board (OLTP) to go head-to-head, but should be in the direction of OLAP. Accompanied by large data ...

Designing 1 applications doesn't seem to be difficult, but it's not easy to achieve the optimal performance of the system. There are many choices in development tools, database design, application structure, query design, interface selection, and so on, depending on the specific application requirements and the skills of the development team. This article takes SQL Server as an example, discusses the application performance optimization techniques from the perspective of the background database, and gives some useful suggestions. 1 database design to achieve optimal performance in a good SQL Server scenario, the key is to have 1 ...

In mailbox rapid expansion process, one of the performance problems is the MongoDB database level write lock, the time spent in the lock waiting process, directly reflects the user's use of the service process delay. To address this long-standing problem, we decided to migrate a common set of MongoDB (storing mail-related data) to a separate cluster. According to our inference, this will reduce the lock latency by 50%, and we can add more fragments, and we expect to be able to optimize and manage different types of data independently. We start from Mon ...

Cost comparisons are easy for cloud computing providers, but performance comparisons for applications are not as simple as comparing performance comparisons of the different types of database applications running in the same cloud or across different cloud computing environments. The Yahoo Cloud computing Service Benchmark (YCSB) is a test framework designed to help users understand the performance of different cloud computing databases and store data performance under actual load. The source code for this test framework is available from the GitHub download. Yahoo cloud services benchmark tools include ...

Japan's Hitachi International Electric Company has developed a new surveillance camera that can search 36 million faces in its database for a similar face within a second after a person's face is photographed. Often this kind of work requires a long time comparison in the database, and the company's new technology is able to perform algorithmic human face contrast. It helps to monitor or locate customers or pedestrians in the face database from stores to government agencies. If the camera photographed a thief in the store, the suspect's image could be singled out, and Hitachi's software would look for suspects in its database ...

Chinese netizens often feel that visiting domestic websites is very fast, while browsing overseas websites is very slow, and also the speed of overseas clients visiting Chinese websites is very slow, which seriously affects the global promotion of Chinese foreign Trade enterprises. The main reason is the limit of China's export total bandwidth. 　　According to the latest statistics of the Internet Information Center (CNNIC), China's export total bandwidth is only more than 80 g, the poor export bandwidth, only one-eighth of a university in the United States. The United States mainframe is placed in the U.S. network environment and resources the most advantage of the top national data center and mention ...

Large data areas of processing, my own contact time is not long, formal projects are still in development, by the large data processing attraction, so there is the idea of writing articles. Large data is presented in the form of database technologies such as Hadoop and "NO SQL", Mongo and Cassandra. Real-time analysis of data is now likely to be easier. Now the transformation of the cluster will be more and more reliable, can be completed within 20 minutes. Because we support it with a table? But these are just some of the newer, untapped advantages and ...
