What is the architecture of MongoDB?
It is an architecture that is built on collections and documents. The basic unit of data in this database consists of a set of key-value pairs. It allows documents to have different fields and structures. This database uses a document storage format called BSON which is a binary style of JSON documents.
What is structure of MongoDB explain each term?
MongoDB is a document-oriented NoSQL database used for high volume data storage. Instead of using tables and rows as in the traditional relational databases, MongoDB makes use of collections and documents. Collections contain sets of documents and function which is the equivalent of relational database tables.
What are the main components of MongoDB?

What is MongoDB explain features of MongoDB?
MongoDB is an open-source document-oriented database that is designed to store a large scale of data and also allows you to work with that data very efficiently. It is categorized under the NoSQL (Not only SQL) database because the storage and retrieval of data in the MongoDB are not in the form of tables.
What is the purpose of MongoDB?
MongoDB is built on a scale-out architecture that has become popular with developers of all kinds for developing scalable applications with evolving data schemas. As a document database, MongoDB makes it easy for developers to store structured or unstructured data. It uses a JSON-like format to store documents.
What is MongoDB and its advantages?
MongoDB is a document-based database solution. It has attributes like replication and gridFS. Its attributes allow an increase in data availability. It is also easy to access documents using indexing. MongoDB performs 100 times faster than other relational databases and provides high performance.
What are tables called in MongoDB?
Collection
What’s called Table in RDBMS is called a Collection in MongoDB. Similarly, a Tuple is called a Document and A Column is called a Field. MongoDB provides a default ‘_id’ (if not provided explicitly) which is a 12-byte hexadecimal number that assures the uniqueness of every document.
Which programming language does MongoDB use?
MongoDB uses the MongoDB Query Language (MQL), designed for easy use by developers. The documentation compares MQL and SQL syntax for common database operations.
What is JSON format in MongoDB?
In MongoDB, data is stored as documents. These documents are stored in MongoDB in JSON (JavaScript Object Notation) format. JSON documents support embedded fields, so related data and lists of data can be stored with the document instead of an external table. JSON is formatted as name/value pairs.
What is difference between MongoDB and SQL?
SQL databases are used to store structured data while NoSQL databases like MongoDB are used to save unstructured data. MongoDB is used to save unstructured data in JSON format. MongoDB does not support advanced analytics and joins like SQL databases support.
What are the benefits of MongoDB?
Advantages of MongoDB
- Flexible document schemas.
- Code-native data access.

Which are the most important features of MongoDB?
Let’s take a look at MongoDB’s top five technical features:
- Ad-hoc queries for optimized, real-time analytics.
- Indexing appropriately for better query executions.
- Replication for better data availability and stability.
- Sharding.
- Load balancing.
How do I create MongoDB?
To access the MongoDB shell,open a terminal window,and run the following command: mongo You are now in the MongoDB shell and can start issuing database commands.
What is schema in MongoDB?
MongoDB provides the capability for schema validation during updates and insertions. Data Modeling Concepts. The core documentation detailing the decisions you must make when determining a data model, and discussing considerations that should be taken into account.
What are the features of MongoDB?
MongoDB, a NoSQL database, is leading the market with many commendable features to its credit. These include exemplary features of MongoDB such as JSON or BSON Data Storage, Power Performance, and Horizontal Scaling.
