Three Types Of Databases

MongoDB is currently the best document-oriented free Open-source NoSQL database. If you are preparing to participate in a technical interview for the MongoDB NoSQL database, you might want to look at the following MongoDB NoSQL interview questions and answers. These MongoDB NoSQL interview questions cover the basic concepts of NoSQL databases, replication (Replication), fragmentation (Sharding), Transactions and locks, trace analysis Tools (Profiler), nuances, and logging features. Let's look at the following ...

"Editor's note" with the development of artificial intelligence technology, the major technology companies have increased their investment in deep learning, and as the National Science Foundation is the same, now, it through the funding of the United States University researchers, to promote the depth of learning algorithms on the FPGA and super computer running. Although it is only a trend that represents the depth of learning, but with the business operations of major technology companies and more in-depth study into the University Research Center and the National Laboratory, the development of in-depth learning to play a positive role in promoting. The following is the original: machine learning in the past few years ...

"IT168" I have always felt that nosql in fact very easy to understand, I have also had a very in-depth study of NoSQL, but in the recent preparation of yuntable chart, found that NoSQL not only very profound, 　　And my personal understanding of NoSQL is only superficial, but I am still a "shame and then Yong" people, so after a period of study, from the sixth part of this series, will talk to you nosql, and this article will be the main to do a NoSQL database review. ...

Enterprises in the process of information often use a number of systems such as enterprise resource planning (Enterprise Resource planing,erp), Customer relationship management (customers relationship MANAGEMENT,CRM), etc. The database data used by these systems are independent, which increases the difficulty of managing costs and maintenance. Private cloud and database consolidation can reduce system costs and complexity, improve flexibility and quality of service; Private cloud can be implemented for servers, storage, applications, or IT services ...

With the rise of internet web2.0 websites, the relational database has become a very hot new field, the development of the non relational database products is very rapid. 　　But the traditional relational database in dealing with web2.0 website, especially the super large-scale and high concurrent SNS type web2.0 pure dynamic website already appeared to be powerless, has exposed many insurmountable problems, for example: 1, high configured--to the database higher concurrent reads and writes the demand WEB2.0 website to be based on user personalized information to generate real-time dynamic ...

OpenStack actually has three storage-related components, and these three components are well known to coincide with the timing of the component itself, arranged as follows: swift--provides object storage, which is conceptually similar to Amazon S3 Services, However, Swift is highly scalable, redundant, and persistent, and also compatible with the S3 API glance--provides virtual machine mirroring (image) storage and management, including many with Amazon AMI catalog ...

In recent years, with the development of science and technology, business expansion, more and more enterprises feel losing control of the data. As one of the important core components of IT system, the database carries important information data. The data form multiplication, the data capacity growth rate is also very astonishing, lets the enterprise's data environment almost cannot bear. At the same time, the day-to-day backup, optimization, expansion, and high availability working hours of the DBA (database administrator) are cyclical, as data maintenance management becomes increasingly onerous. How can we solve the above problems? With cloud computing technology ...

Introduction: Open source data processing platform with its low-cost, high scalability and flexibility of the advantages has won the majority of network Giants recognized. Now Hadoop will go into more business. IBM will launch a DB2 flagship database management system with built-in NoSQL technology next year. Oracle and Microsoft also disclosed last month that they plan to release a Hadoop-based product next year. Two companies are planning to provide assistance with deployment services and enterprise-level support. Oracle has pledged to preinstall Hadoop software in large data devices. Large Data Leather ...
