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

Test and use of Redis in Windows using NoSQL, nosqlredis About NoSQL Before introducing Redis, I 'd like to know NoSQL, that is, not only SQL, which is a non-relational data storage and key/value pair storage. Existing Nosql DB products: redis/MongoDB/Memcached/Hbase/Cassand

transformation from character stream to Dom. NoSQL is stored in JSON, providing support for the original ecosystem, which is much more efficient than traditional relational databases.3) High Concurrent database requestsThis kind of application is common in Web2.0 's website, many applications for data consistency requirements are very low, but the relational database transaction and large table join instead become "performance killer". In the case of

Introduction and use of the nosql database CodernityDB developed in Python only, nosqlcodernitydb Look at this logo. It's a bit python-like. The database codernityDB introduced this time is developed in python only. I used the tinyDB local database and an api service. At first, I thought the speed was a little poor. The result showed that the implementation method was really amazing, it is actually the sto

handles plus stdin, stdout, stderr, and so on is 20. Although a mixed-record structure is appropriate for non-relational or NoSQL APIs, because there is no pattern required, developers often face situations where a technique is needed to use a pattern. A consistent pattern definition for some software using SQL (or ODBC, etc.) is required, such as a large number of third-party reporting and analysis tools

In the past few years, relational databases have been the only choice for data persistence. Data workers only consider filtering these traditional databases, such as SQL Server, Oracle, or MySQL. You can even make some default options. For example, if you use. net, you generally select SQL server. If you use Java, you may prefer Oracle, Ruby is MySQL, and python is PostgreSQL or MySQL. The reason is simple:

In the past few years, relational databases have been the only choice for data persistence, and data workers are only looking at these traditional databases for filtering, such as SQL Server, Oracle, or MySQL. Even make some default choices, such as use. NET will generally choose SQL Server, Java may be biased to Oracle,ruby is Mysql,python is PostgreSQL or MySQL and so on.The reason is simple: the robustness of relational databases has been proven in

basic operations, Hong Kong servers, and some precautions. Database CRUD operations will introduce the path to NoSQL learning in the following sections (4): Creating, reading, updating, and deleting (CRUD) Enter the Command Prompt (cmd.exe ). Go to the bin directory of the MongoDB decompressed Directory, that is, D: \ NoSQL \ mongodb-win32-x86_64-2.4.3 \ bin then execute mongo.exe (or mongo) to start Mongo

1.NOSQL IntroductionNOSQL (not only Sql) refers to a non-relational database. The next generation of databases mainly solves several key points: non-relational, distributed, open-source, horizontally extensible. The original goal was for large-scale Web applications, which began in the early 2009 with features such as freedom of mode, support for simple replication, simple APIs, eventual consistency (non-acid), high-capacity data, and so on.

As Web applications become increasingly complex, simple MySQL + Memcached seems to be unable to meet the needs of data storage. Some enterprises have switched to NoSQL solutions, such as MongoDB, CouchDB, TokyoCabinet/Tyrant, and Cassandra. In their opinion, if the data access mode is not very complex, SQL databases will not be used. However, DeNA chose the "only MySQL" solution and achieved far better performance than

I like MySQL not only because of its simple use, but also because of its open source, plug-in engine, and better plug-in!
