Sweep 18 Major databases: 12 species of sql+6 nosql remember that two or three years ago there were only a few cloud platform vendors to choose from, it seems that there is not much cloud database in the market. But after the cloud boomed, the cloud database also appeared to be springing up. And what is really reliable and easy to use, for users, and bad analysis.

There are still deficiencies, I hope to hear more ...

The big figures, which emerged in 2011 and soar in 2012, may change many aspects of data management in a dramatic way. Large data systems have brought about changes in the management and manipulation of computer data, continuous extraction, transformation and loading functions, operational business intelligence, dynamic large data, and cloud-based data warehouses. However, with large data entering the 2013, there is no system technology more active than the NoSQL database and Hadoop framework, it seems that these two products have more room for development. According to the marketanalysis ....

"The role of data storage is changing, one of the factors is that data is becoming more and more complex, and for a data storage system designed 5-10 years ago, it must be able to handle the diversity of resources," said Donald Feinberg, the analyst's Vice president Complexity, large capacity, and system response speed to real-time and other characteristics. And he argues that while big data has different meanings for different industries, basically large data represents large, complex, unstructured data. However, for good at dealing with knots ...

One, the charm of the management of cloud computing is that users can start using their ID card and credit card, but that's the problem.

This will force major competitors such as IBM, HP and SAP to come up with Hadoop products that tightly bundle hardware, software and other tools. On the day of shipment, Oracle announces that its new product will run cloud ...

As data centers, Grid computing, supercomputing, cloud computing and other technologies and concepts rise, IT industry is also moving towards business model, technology architecture to management operations and other aspects of the direction of change. At the same time, cloud management technology has gradually entered our vision, the topic of cloud management also more and more hot. In terms of user requirements, technical features and functional composition, cloud management is mainly the management of data centers. The management focuses on the integration of key resources and business, visualization and virtualization, while Cloud management focuses on the allocation of resources on demand and the charging operation of the cloud.

Now everyone is talking about the cloud, and manufacturers are labeling their products and services with cloud computing. 　　This is also the scene of the operating system, where the cloud operating system is simply a simplified operating system that simply runs a Web browser-at least a definition of a cloud operating system that allows users to perform many simple tasks without having to start a full version of the operating system. In a cloud computing environment, applications and data "reside and run" on the internet, rather than "reside and run" on the hard disk. This service is also known as platform as a service (PaaS), and Software as a service (...).
