What is MongoDB?

MongoDB is a C ++ language, is based on a distributed file storage system open source database.

In the case of high load, add more nodes, you can ensure server performance.

MongoDB is designed to provide scalable, high-performance data storage solutions WEB applications.

MongoDB stores data as a document data structure by a key (key => value) pairs. MongoDB document similar to the JSON object. Field value can contain other documents, arrays and array of documents.



main feature

  • MongoDB provides a document-oriented storage, the operation is relatively simple and easy.
  • You can set any properties in MongoDB record index (such as: FirstName = "Sameer", Address = "8 Gandhi Road") to enable faster sorting.
  • You can create a local or network data mirroring, which makes MongoDB there is more scalable.
  • If the load increases (the need for more storage space and more processing power), it can be distributed in a computer network on a different node This is called fragmentation.
  • Mongo supports a rich query expressions. Discover instruction uses JSON form tag can easily query document embedded objects and arrays.
  • MongoDb using the update () command can replace the completed document (data) or some specified data fields.
  • Mongodb in Map / reduce is primarily used for batch processing and data aggregation operations.
  • Map and Reduce. Map function call emit (key, value) loop through the collection of all the records, and the key value passed to Reduce function for processing.
  • Map and Reduce functions are functions written using Javascript, and MapReduce operation may be performed by db.runCommand or mapreduce command.
  • GridFS MongoDB is a built-in function, can be used to store a large number of small files.
  • MongoDB allows the implementation of server-side scripting, you can use Javascript to write a function, executed directly on the server, you can put the function definitions are stored in the server, the next can be called directly.
  • MongoDB supports a variety of programming languages: RUBY, PYTHON, JAVA, C ++, PHP, C # and other languages.
  • MongoDB easy to install.
