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

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

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 systems generally advertise a feature, that is, good performance. Why? After so many years of development in relational databases, various optimizations have been done very deeply. NoSQL systems generally use relational database technology. What factors have bound the performance of relational databases? We can look at this problem from the perspective of system design. 1 .?

Background to the rise of NoSQL:1) The Rise of web2.0 (high interactivity), the traditional relational database in order to ensure the " universality " of the design has brought a complex function, high performance costs, and expensive problems.2) Avoid unnecessary complexity3) Higher throughput and high concurrency4) Ability to scale horizontally on commercial hardware5) NoSQL implementation of large table

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

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
