Schema-less design
Another important feature of MongoDB is its schema-less nature. With a relational database, you are required to define the exact structure of the data being stored ahead of time, which is termed as the schema. This means that you must have defined the exact number of columns, the length, and the data type for every field in a table, and that each field must always match that exact set of criteria. Mongo provides a flexible nature where the documents that you store into the database need not follow any schema unless the developer enforces it through the application level. This makes MongoDB a great fit for Agile-based development, as you could carry out modifications on the application schema on the fly.
