Why use MongoDB?
There are various reasons to use the MongoDB database.
Document-oriented: MongoDB is an object-oriented document database. Instead of using columns and rows to store the data, MongoDB uses a document to store the data.
Indexing: In MongoDB, Indexing is used to boost the performance of search within MongoDB.Any field in a MongoDB document can be indexed.
Replication: MongoDB provides a high availability of replica sets. A replica set contains two or more copies of the data. each replica set may act in the role of the primary and secondary replica at any time.
Load Balancing: MongoDB can run on multiple servers. Balancing the load to keep the system up.
File system: MongoDB can be used as a file system with load balancing and data replication features over multiple machines for storing files.
MongoDB Features: There are various features in the MongoDB database.
Indexing: You can index any field in the document.
Support ad hoc series: In MongoDB, you can search any field, or range query, and it supports regular expression.
Replication: MongoDB database supports master-slave replication.
Load balancing: MongoDB supports automatic load balancing because of data placed in shards.
Duplicate data: MongoDB can run multiple servers. The duplicate data can be kept on multiple servers to keep the system up.
Provide high performance.
Use JavaScript instead of procedure.
Transaction: MongoDB supports multiple document ACID transactions.
Server-side javascript execution: JavaScript can be used in a query, or aggregation function, and sent directly to the database to be executed.
MongoDB Example:
The below example shows how document models in MongoDB.
{
first_name:"Vishvajit",
last_name:"Rao",
phone:99xxxxxxxx,
Occupation:"Software Engineer"
}MongoDB stores data in the format of key/value pairs. MongoDB stores data as a document, so it is known as a document-oriented database.
As you can see in the above example field and value are separated by a colon ( : ). A MongoDB document looks like a JSON format.
