For every web and mobile application that focuses on the user experience, memory-based NoSQL storage systems such as open source Redis and memcached are becoming de facto standards. However, in recent years, the use of these databases by large enterprises has been slow, due mainly to performance, scalability and availability challenges. Fortunately, the modern programming language (Ruby, Node.js and Python, as well as development platforms (Rails,sin

Advantages and disadvantages of relational databaseAdvantages: Can do transaction processing, so as to ensure the consistency of data; Can be a join, such as multi-table query; Because of SQL standardization, the cost of data updates is small (the same fields are basically only one place). Disadvantages: The write processing of large amount of data is not easy; If the table data volume is too large, it is not easy to do index or table structure update; When the field is

NoSQL databases are becoming more and more popular. here I have summarized some very good,

[51CTO external headlines] We once discussed "What role does NoSQL play in our work ?" We have also raised 101 questions about how to choose a NoSQL database. We even held an online seminar to thoroughly analyze what SQL, NoSQL, or applications can bring to the scalability of Web applications. [51CTO external headlines] We once discussed "What role does

First, the concept of SQL (structured Query Language) database, refers to the relational database.　　Main representative: SQL Server,oracle,mysql (open source), PostgreSQL (open source). NoSQL (not only SQL) refers to a non-relational database.Main representative: MONGODB,REDIS,COUCHDB. Second, the difference1.

The scalability of NoSQL systems is the main reason for the development of NoSQL, including distributed system coordination, failover, resource management and many other features. In this case, NoSQL sounds like a big basket, and everything can be inserted. Although the NoSQL movement has not brought about fundamental

Why is there NoSQL? With the development of the Internet, when we turn a server into two servers, when we start to build data backup, when we need to add a buffer layer, to adjust all the query, put more hardware.Finally, it is necessary to divide the data into multiple clusters and reconstruct a large number of application logic to fit the segmentation. After a while, you'll find yourself constrained by the data structure you've been designing a few
