advantages of nosql

As we all know, relational data types have always been one of SQL's criticism. With the increasing variety of data, the conversion from various data types to relational data types has plagued most SQL database users. However, the advantages of SQL databases are undeniable. If you can have both the fish and the bear's paw-implementing nosql Data Types in the SQL database, isn't everything a wonderful change

Domestic also has the document type database SEQUOIADB, already open source.Graph Database (graph)The graphical structure of the database is different from the other columns and the rigid structure of the SQL database, it is using a flexible graphical model, and can be extended to multiple servers. NoSQL databases do not have a standard query language (SQL), so database queries require a d

Maintain data consistency (transaction processing)2. Due to standardization, the cost of updating data is small (the same fields are basically only one place)3. Complex queries such as joins can be madeOne of the best advantages of re

NoSQL refers to a non-relational database, and we often use relational databases. Like our usual mysql,sqlserver, these databases are typically used to store important information, and there's no proble

Typical scenario: Web applications (similar to Key-value, value is structured, but the database is able to understand the content of value) Data model: Key-value corresponding key-value pairs, value is structured data Advantages and Disadvantages: The data structure req

MySQL can fully meet, because the optimized K/V Request, at the SQL layer of MySQL, the qps of each core is about 5 kb, which is greatly improved after HandlerSocket is released. HandlerSocket plugin for MySQL has been out for some time. Given the robustness and security of HandlerSocket and InnoDB, it is foreseeable that HandlerSocket replaces NoSQL storage/Cache such as Memcached, which is the trend of the times. HandlerSocket is a plug-in of MySQL

Just a few years ago, MySQL was recognized as the king of the open source database field. However, as nosql grew at a compound growth rate of 82% per year, MySQL is facing the risk of being eliminated by nosql in the Web application market. The migration to nosql has not only become a concern for the development trend of the IT industry, but also allows people to

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

Label:In the past, we only needed to learn and use a database technology to do almost all of the database application development. Because the mature and stable relational database products are not many, and for you to choose the free version is even less, so the Internet domain basically chose the free MySQL database. In the rapid development of the WEB2.0 era, we found that the relational database in performance, scalability, rapid data backup and recovery, to meet the needs of the ease of use

Data Model: Graph structure Advantages: Using graph structure correlation algorithm Disadvantage: The whole graph needs to be calculated to produce results, it is not easy to do distributed cluster scheme 1.2NoSQL Features1. Easy to expand There are many kinds of nosql databases, but a common feature is to remove the relational characteristics of relational databases.
