Tags: nosql databases NoSQL Databaserelational database valueIn the study of NoSQL is we certainly think of the current database mainstream ———— SQL database. Why SQL database is now the mainstream, mainly based on the following advantages:Get persisted data: mainly because of the two storage areas in the computer architecture, primary storage and backup memory.C

No-sql database: not just SQLDefinition: Non-relational database; NoSQL is used for storage of hyper-scale data. (for example, Google or Facebook collects trillions of bits of data for their users every day). These types of data stores do not require a fixed pattern and can be scaled horizontally without extra action. Further data mining and analysis is required.RDBMS VS NOSQL Rdbms

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 most applications over a long period of time

Oracle, as the world's largest relational Database provider, has also joined the NoSQL Database chain in its product chain. In addition, this new Database name is so domineering that it is called NoSQL Database. Oracle's NoSQL Database is one of the components of the Big Data Appliance released on Oracle's global Daquan in October 4, big Data Appliance is a syst

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

Tags: read and write Data features Big Data NoSQL Database div High available implementation L databaseEasy to scale: NoSQL databases have a wide variety, but a common feature is the relationship-based nature of relational databases. there is no relationship between the data, which makes it very easy to scale up large data volumes, high performance: NoSQL

New requirements for database in new application-Low latency under high concurrency for Read and write requests-Effective big data storage and access requirements (PB level)-High scalability and high availability-smaller administrative and operational costsLimitations of traditional relational databases-Due to the logical complexity of the relational database, a lot of deadlock or concurrency problems occur as the data size increases, which slows down the reading and writing speed.-Capacity limi

Label:All along, the use of big data is far less than the big data collection ability, the main reason is that the current enterprise data is mainly scattered in different systems or organizations, big Data strategy is to be able to more depth, more abundant mining all data system valuable information, so as to more accurately predict customer behavior, find business value, However, it is difficult to move this data to a separateData storage, security and regulatory issues are not guaranteed, an
