Install mongodb in linux universal Binary Package, mongodblinux
MonfoDB is an open-source document database that provides common performance, high availability, and automatic scaling.
The record in MongoDB is a document, which is a structure consisting of fields and values. Mongodb documents are similar to JSON objects. Field Values can contain arrays of other documents, arrays, and documents. Records are organized into collections, which is equivalent to tables. Refer:
The advantages of using documents are:
Documents correspond to endogenous Data Objects in many programming languages
Embedded documents and arrays reduce join overhead
Dynamic schema supports smooth Polymorphism
Key features:
High performance:
Mongodb provides high-performance data persistence. In particular:
Supports embedded data models to reduce the I/O of the Database System
Indexes support quick queries and embedded documents and arrays can contain keys.
High Availability:
Mongodb provides highly available replica sets.
Automatic failover failure
Data redundancy
Replica set is a group of mongodb servers that maintain the same dataset, provide redundancy, and increase data availability.
Automatic horizontal scaling:
Horizontal scaling is the kernel function of mongodb.
Automatically share distributed data on the Cluster
Replica sets can provide eventual consistent reads for applications with low latency and high throughput.
