Introduction of MongoDB
MongoDB is a document-oriented NoSQL database used for high-volume data storage. MongoDB is a database that came to light around the mid-2000s. It comes under the category of a NoSQL database.
This kind of DBMS uses dynamic schemas which means that you can create records without first defining the structure, such as the fields or the types and their values.
MongoDB allows you to change the structure of records, which we call documents by adding new fields or deleting existing ones.
Features of MongoDB
Here, are the important features of MongoDB:
- Each database contains collections which in turn, contain documents.
- Each document can be different with a varying number of fields. The size and content of each document can be different from each other.
- The document structure of MongoDB is according to how developers construct their classes and objects in their respective programming languages.
MongoDB is a well-established, non-relational database system offering improved flexibility and horizontal scalability, but at the cost of some safety features of relational databases, such as referential integrity.
