Is MongoDB part of SQL?

MongoDB is a NoSQL Server in which data is stored in BSON (Binary JSON) documents and each document is essentially built on a key-value pair structure. As MongoDB easily stores schemaless data, make it appropriate for capturing data whose structure is not known.

Is MongoDB SQL based?

MongoDB is what is called a NoSQL database. This means that pre-defined structure for the incoming data can be defined and adhered to but also, if required different documents in a collection can have different structures.

Is MongoDB a NoSQL or MySQL?

Key features of MongoDB Unlike MySQL, MongoDB a document-oriented NoSQL database system that consists of collections and documents. MongoDB is a schema-less database system, which means that documents in the same collection can have different structures. Here are a few more key features of MongoDB.

What is MongoDB?

MongoDB (link resides outside IBM) is an open source, nonrelational database management system (DBMS) that uses flexible documents instead of tables and rows to process and store various forms of data. As a NoSQL solution, MongoDB does not require a relational database management system (RDBMS), so it provides an elastic data storage model that enables users to store and query multivariate data types with ease. This not only simplifies database management for developers but also creates a highly scalable environment for cross-platform applications and services.

Which is better, MySQL or MongoDB?

Because of its rigid nature, MySQL is preferable to MongoDB when data integrity and isolation are essential, such as when managing transactional data. But MongoDB’s less-restrictive format and higher performance make it a better choice, particularly when availability and speed are primary concerns.

What are the advantages of MongoDB?

One of MongoDB’s biggest advantages over other databases is its ability to handle ad hoc queries that don’t require predefined schemas. MongoDB databases use a query language that’s similar to SQL databases and is extremely approachable for beginner and advanced developers alike.

Why is MongoDB sharding?

As enterprises' cloud applications scale and resource demands increase, problems can arise in securing the availability and reliability of services. MongoDB’s load balancing sharing process distributes large data sets across multiple virtual machines at once while still maintaining acceptable read and write throughputs . This horizontal scaling is called sharding and it helps organizations avoid the cost of vertical scaling of hardware while still expanding the capacity of cloud-based deployments.

Does MongoDB require RDBMS?

What is a MongoDB replica set?

MongoDB provides high availability with replica sets. A replica set consists of two or more copies of the data. Each replica-set member may act in the role of primary or secondary replica at any time. All writes and reads are done on the primary replica by default. Secondary replicas maintain a copy of the data of the primary using built-in replication. When a primary replica fails, the replica set automatically conducts an election process to determine which secondary should become the primary. Secondaries can optionally serve read operations, but that data is only eventually consistent by default.

What is grid file system?

This function, called grid file system, is included with MongoDB drivers. MongoDB exposes functions for file manipulation and content to developers. GridFS can be accessed using mongofiles utility or plugins for Nginx and lighttpd. GridFS divides a file into parts, or chunks, and stores each of those chunks as a separate document.

How does MongoDB scale?

MongoDB scales horizontally using sharding. The user chooses a shard key, which determines how the data in a collection will be distributed. The data is split into ranges (based on the shard key) and distributed across multiple shards. (A shard is a master with one or more replicas.). Alternatively, the shard key can be hashed to map to a shard – enabling an even data distribution.

What is MongoDB query?

MongoDB supports field, range query, and regular-expression searches. Queries can return specific fields of documents and also include user-defined JavaScript functions. Queries can also be configured to return a random sample of results of a given size.

Why is MongoDB removed from Linux?

Is MongoDB a database?

MongoDB is not a Relational Database Management System (RDBMS). It's called a "NoSQL" database. It is opposite to SQL based databases where it does not normalize data under schemas and tables where every table has a fixed structure. Instead, it stores data in the collections as JSON based documents and does not enforce schemas. It does not have tables, rows, and columns as other SQL (RDBMS) databases.

How Does MongoDB Work?

MongoDB stores data objects in collections and documents instead of the tables and rows used in traditional relational databases. Collections comprise sets of documents, which are equivalent to tables in a relational database. Documents consist of key-value pairs, which are the basic unit of data in MongoDB.

How Does MongoDB Text Search Work?

A key feature of MongoDB is the text search, which can query string fields for specific text or words . A text search can be performed using a text index or the $text operator.

What is MongoDB?

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. Documents consist of key-value pairs which are the basic unit of data in MongoDB. Collections contain sets of documents and function which is the equivalent of relational database tables. MongoDB is a database which came into light around the mid-2000s.

What is a MongoDB replica?

Replication – MongoDB can provide high availability with replica sets. A replica set consists of two or more mongo DB instances. Each replica set member may act in the role of the primary or secondary replica at any time. The primary replica is the main server which interacts with the client and performs all the read/write operations. The Secondary replicas maintain a copy of the data of the primary using built-in replication. When a primary replica fails, the replica set automatically switches over to the secondary and then it becomes the primary server.

How does MongoDB scale?

Load balancing – MongoDB uses the concept of sharding to scale horizontally by splitting data across multiple MongoDB instances. MongoDB can run over multiple servers, balancing the load and/or duplicating data to keep the system up and running in case of hardware failure.

What is a collection in MongoDB?

Collection – This is a grouping of MongoDB documents. A collection is the equivalent of a table which is created in any other RDMS such as Oracle or MS SQL. A collection exists within a single database. As seen from the introduction collections don’t enforce any sort of structure.

What is a document in MongoDB?

Document - A record in a MongoDB collection is basically called a document. The document, in turn, will consist of field name and values. Field - A name-value pair in a document. A document has zero or more fields. Fields are analogous to columns in relational databases.

What is ad hoc query in MongoDB?

Ad hoc queries – MongoDB supports searching by field, range queries, and regular expression searches. Queries can be made to return specific fields within documents.

What is the difference between a MongoDB and a RDBMS?
