The scalability of the system is the main reason for the development of the NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket, and everything can be plugged in. Although the NoSQL movement does not bring fundamental

As a result, there is a nosql era that uses Google, Facebook, and Amazon to handle more data transmission. Nosql Era There are already many nosql databases, such as MongoDB, redis, Riak, hbase, and Cassandra. Each has one of

Comparison and Analysis of eight common NoSQL Database Systems Krist óf kolács is a software architect and consultant who recently published an article comparing various NoSQL databases. Although SQL database is a very useful tool, after 15 years of outstanding performance, the monopoly will be broken. This is only a matter of time: I was forced to use relational databases, but I finally found that I could

revolutionary new database movement. NoSQL advocates the use of non-relational data storage. Today's computer architecture requires massive horizontal scalability in terms of data storage, while NoSQL is committed to changing this situation. Currently, Google BigTable and Amazon Dynamo use NoSQL databases. 1. CouchDB

As we all know, the nosql movement aims to become a substitute for traditional relational database management systems in the big data era. Ravendb is a good example of Microsoft's changing attitude towards open source. Microsoft's acceptance of ravendb (nosql database) surprised many people. Ravendb can easily replace the relational database management system and be compatible with previous. NET application

What is the comparison between nosql and relational databases? Advantages: 1) Cost: nosql databases are simple and easy to deploy. They are basically open-source software and do not need to be purchased and used at the same cost as Oracle, which is cheaper than relational databases. 2) query speed: nosql databases store data in the cache, relational database

, for example, the data version is recorded in the read phase, and the version is checked during write. If any inconsistency is found, the entire read-test-write process is retried. Base is mainly used for multiple business systems. This concept is not mentioned in the storage system. For an SQL system like a database, it is the acid consistency model; for a nosql system like GFS + bigtable, It is the consistency model of a single row transaction; i
