Label:The IT world is embracing "big data" quickly. Huge data storage will be the next topic of big Data analytics, as big data is getting bigger, for example, startups are using these systems to analyze the history of human evolution with trillions of DNA testing strips. While big data (and its underlying technology NoSQL) is becoming a buzzword in the information systems community, there is not much discussion about the security implications of big

Is NoSQL true or not? To NoSQL or not toNoSQL With the emergence of a large amount of data, NoSQL database architecture is being used by more and more people, because NoSQL architecture is more effective in big data processing. Today, when you need to store and process high-capacity data, many young developers prefer o

Label:NoSQL(NoSQL = Not Only SQL )，意即"不仅仅是SQL"。 On modern computing systems, a huge amount of data is generated every day on the network. A significant portion of this data is handled by the relational database management system (RDMBSS).

NoSQL in 2010, big and small web site in the pursuit of high-performance high reliability, involuntarily chose NoSQL technology as a priority. At the beginning of this year, the Infoq Chinese station was fortunate enough to invite Mr. Sun Li of Phoenix to share his experiences and experience in NoSQL. It is a great honor to be invited to open up such a column on

Label:MySQL is now a better nosql solution. We say this because MySQL has the advantage of performance, ease of use, and stability when storing data such as key/value (Key/value). The MySQL engine is robust and well-supported by the community and the official, with a very rich online profile covering a variety of operations, troubleshooting, replication, and various usage patterns. For this reason, MySQL has a big advantage over the emerging

10 things you should know about NoSQL Databases Since the 1/4 century, relational databases (RDBMS) have been the mainstream database models. But now non-relational databases, "Cloud" or "NoSQL" databases, are gaining an increasing share as an alternative database model. In this article, we will focus on the 10 key features of non-relational NoSQL databases: the

NoSQL Basic LearningThe first nosql to learn recently is MongoDB, in order to understand the basics of nosql, to summarize, mainly to learn the theory of NoSQLI. Introduction (INTRODUCTION)It is the abbreviation of "not only SQL", non-relational database, it has very good versatility and very high performance, it has the advantage in processing a large amount of

Label:I had always thought that NoSQL was easy to understand and I had a very thorough study of nosql myself, but in the recent preparation of the yuntable chart, I found that NoSQL was not only very profound, but also my personal understanding of NoSQL was just fur. But I am a "shame and then brave" people, so after a

NoSQL has now become a very popular topic in the IT industry. In this article, we will introduce you to the basic knowledge of CouchDB, a member of NoSQL, and take you into the world of NoSQL. What is NoSQL? NoSQL (short for not only SQL, also known as non-relational, or no

At the same time, NoSQL, as a new technology in recent years, has received more and more attention. This article will be based on the DBA work of Mr. Meng Xianhao, and the relevant experience of big data operations, to share two main directions: first, the company's structure evolution on KV storage and the problems that ne

storage (disk space) is negligible. While non-relational data is stored in a flat dataset, data can often be duplicated. A single database is rarely separated, but stored as a whole, so that it is easier to read and write for the whole piece of data. Vertical Expansion vs Horizontal expansion The biggest difference between SQL and NoSQL databases may be in scaling, and of course scaling up to support the growing demand. To support more concurrency, S

Although the 09 appeared a more radical article "Relational database is dead", but we all know that the relational database is actually alive and well, you can not use the relational database. But it also illustrates the fact that the relational database has a bottleneck when it comes to processing WEB2.0 data.So are we using NoSQL or relational databases? I don't think we need to have an absolute answer. We need to decide what we use based on our app
