cannot run well on clusters. You may also build a relational database cluster, but they use shared storage, which is not the type we want. 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,

MongoDB Website data: MongoDB is ideal for real-time insertion, update, and query. It also supports the replication and high scalability required for real-time website data storage. Cache: because of its high performance, MongoDB is also suitable for serving as the cache layer for information infrastructure. After the system is restarted, the persistent cache layer established by MongoDB can avoid data source overload at the lower layer. Large-sized and low-value data: traditional relationa

relational database. Features of NoSQL The emergence of NoSQL mainly aims to solve the problem of database read/write performance. With the emergence of a growing number of Web application systems, such as SNS and Weibo, a large amount of data needs to be read and written, in addition, distributed deployment is required, while traditional relational data models often need to connect multiple tables in the

term "NoSQL" was formally presented, with a total of 225 solutions now.The difference between NoSQL and Rdmbs is mainly at two: first, it provides modeless flexibility to support flexible schema changes, and secondly, scalability, native RDBMS only applies to standalone and small clusters. NoSQL was distributed at the outset, addressing both read-write and capac

Install the Linux system (Ubuntu 10.04 server) and install the additional open SSH-server. Machine name: ubuntu (CAT/etc/hostname, the result is UBUNTU) 2. install Java and set environment variables.

Fast-changing application environments require a flexible mechanism for storing data and passing data between different application tiers. As it turns out, JSON (Java Script Object notation) is an important technology for moving, interactive applications that reduces the overhead of pattern design and eliminates the need for data conversion. DB2 NoSQL JSON enables developers to write applications using the JSON-oriented popular query language created
