MongoDB Developing Services uses collections and documents rather than tables and rows as in traditional relational databases. Documents are made up of key-value pairs, which are the fundamental unit of data in MongoDB. Collections are similar to relational database tables in that they include collections of documents and functions. MongoDB is a database that originally surfaced in the mid-2000s. Each database includes collections, which include documents.MongoDB is a document-oriented database, not a relational one. It is non-relational in the sense that it does not store data in tables but rather in the form of a JSON document. The fundamental rationale for abandoning the relational paradigm is to make scaling out easier. In MongoDB, a row is replaced with a document, and a table is replaced with a collection. It may be conceived of as a collection of documents.
You can always import the entire data set from MongoDB Developing Services to R’s in-memory for much simpler data exploration with packages like mongolite,’ ‘dplyr,’ and ‘tidyr.On the file system, each database has its own collection of files. Multiple databases can be stored on a MongoDB server.
Document – A document is essentially a record in a MongoDB collection. The document will then be made up of field names and values.
A name-value pair in a document is referred to as a field. A document can have one or more fields. In relational databases, fields are equivalent to columns. The figure below depicts an example of Fields with Key value pairs. So, in the following example, CustomerID and 11 are two of the key value pairs declared in the document.MongoDB was web development by 10gen software business in 2007 as part of a proposed platform as a service solution. The firm switched to an open-source development strategy in 2009, offering commercial support and other services. MongoDB Inc. took the place of 10gen in 2013.
