MongoDB is the most popular NoSQL database, an open-source document-oriented database used for high volume data storage. This NoSQL database stores data in BSON format – a binary encoding JSON that stores data in key-value pairs.
Launched in the year 2007, MongoDB database is built for easy scalability, maximum availability, and good performance. Developers use this database to build apps quickly, as they don’t need to use stored procedures anymore. MongoDB also offers numerous options for maintaining the consistency of the data.
MongoDB, written in C++ language, is a schema-less database that is more flexible than traditional tables. It has no schema to have many fields, content, and size different from another document in the same collection.
MongoDB has been developed on a scale-out architectural format, thus making it easy for developers to work with, especially to craft apps with changing data schemas that can be scaled. This NoSQL database can save, manage, update, and extract data without hassles.
MongoDB has a dynamic and elastic schema, thus, adding and eliminating fields is very easy. As developers look after the schema, they can fine-tune and reformat it as the app progresses.
MongoDB is considered the pioneer among NoSQL databases that came into existence as SQL-based RDBMS. It provided little support for scaling and speedy development cycles which were necessary for creating sophisticated apps.
As MongoDB retrieves documents in JSON format, it is easily readable by humans; after all, it’s the natural form of data storage. The JSON format can be settled for putting away data objects that are intricate.
Moreover, data can be parsed quicker with the BSON format, which also enables indexing and searching to boost performance significantly. One can also use Text, partial, geospatial, decimal, and other varieties of indexing methods.
Although MongoDB has wide application, it is more commonly used for the following:
● Building mobile & social infrastructure
● Managing & delivering content
● Managing user data
● Big Data
● Data Hub
At present, MongoDB is being utilized as backend software by various significant websites and services including EA, Cisco, Shutterfly, Adobe, Ericsson, Craigslist, eBay, and Foursquare.
MongoDB provides official driver support to some of the common programming languages including C, C++, Rust, C#, Java, Node.js, Perl, PHP, Python, Ruby, Scala, Go, and Erlang.
There are different terms used in the MongoDB NoSQL database. Some of the important terms used in the MongoDB database include the following:
Document: This is a record in MongoDB where data is stored in key-value pairs.
Collection: This is a group of documents.
Database: A database is a place where all the documents are present.
Key-value pairs: In MongoDB, data is stored in JSON format and JSON stores data in key-value pairs.
JSON: This is a data-interchange format used in MongoDB to store data.
BSON: This is an extended JSON that supports a variety of data types.
_Id: This is auto-generated whenever a document is created. The value of _id is unique.
Although MongoDB provides lots of advantages but also has some limitations. Following are a few disadvantages:
