What is MongoDB?

MongoDB is a document-oriented NoSQL database for storing large amounts of data. MongoDB uses arrays and records instead of tables and lists, as in standard relational databases. Documents are made up of key-value pairs, which are MongoDB's simple data unit. Collections are the equivalent of relational database tables in that they contain collections of records and functions. MongoDB is a relational database management system. MongoDB is a database that came into light around the mid-2000s.

MongoDB Features

1.    Each archive is made up of sets, which are made up of records. Each paper is unique, with a different number of fields. Each document's size and content can vary from one another.

2.    The text structure corresponds to how programmers create classes and objects in their respective programming languages. Developers will often claim that their classes have a simple structure of key-value pairs rather than rows and columns.

3.    There is no need to specify a schema for the rows (or records, as they are known in MongoDB). Fields can be generated on the fly instead.

4.    MongoDB's data model makes it easier to describe hierarchical relationships, store arrays, and store other more complex structures.


What is Mongo DB used for?

Each row in a MongoDB database is a document defined in JSON, a formatting language, rather than tables with rows or columns as in SQL databases. Data libraries are highly adaptable, allowing for changes in document composition as well as the handling of partly completed records.

·      Document Oriented Storage − Data is stored in the form of JSON-style documents.
·      Index on any attribute
·      Replication and high availability
·      Auto-Shading
·      Rich queries
·      Fast in-place updates
·      Professional support by MongoDB


Where to Use MongoDB?

·       Big Data

·       Content Management and Delivery

·       Mobile and Social Infrastructure

·       User Data Management

·       Data Hub

Is MongoDB free to use?

MongoDB's powerful distributed record archive has a Community edition. Download the MongoDB registry to protect and encrypt your data and obtain access to an integrated in-memory storage engine for this free and open database.

Why is MongoDB popular?


Because of its simplicity and ease of use, MongoDB is common among new developers. And if it's easy to use, it has all the features necessary to satisfy the demanding specifications of modern applications. Mongo is popular among developers because it stores all of its documents in JSON format. The security band is also very mature.





Why MongoDB is faster?

MongoDB is fast because it's built for the internet. It's a nice video that everybody can watch, but it answers your question: most NoSQL engines, such as MongoDB, are not stable or immune to crashes and other outages. They are willing to give up protection in order to gain pace.


Is MongoDB Free on AWS?

 

Users are advised to try MongoDB Atlas' free tier on AWS, but there are certain situations where a self-managed version with an existing cloud database or framework makes the most sense.

 

Advantages of MongoDB

ü  Flexible document schemas.

ü  Code-native data access.

ü  Change-friendly design.

ü  Powerful querying and analytics.

ü  Easy horizontal scale-out.

 

Disadvantages of MongoDB

ü  MongoDB uses high memory for data storage.

ü  There is a limit for document size, 16Mb.

ü  There is no transaction support in MongoDB.

Node.js

 Nodejs About Nodejs As an asynchronous event-driven JavaScript runtime, Node.js is designed to build scalable network applications. In the following "hello world" example, many connections can be handled concurrently. Upon each connection, the callback is fired, but if there is no work to be done, Node.js will sleep.  This is in contrast to today's more popular concurrency approach, which employs OS threads. Thread-based networking is wasteful and complex to implement. Furthermore, because there are no locks, Node.js users are not concerned about deadlocking the process. Because almost no function in Node.js does I/O directly, the process never blocks. Scalable systems are very feasible to develop in Node.js because nothing blocks. Getting started with Nodejs The installer package supplied on the NodeJS official website makes the installation of NodeJS and NPM simple. Download the installer from the Nodejs package Run the installer. Follow the installer steps, agree to t...

Front end with React.Js

Image
  What is ReactJS? React is an open-source, reusable component-based front-end JavaScript library. React was created by Jordan Walke on the 29 th of May 2013, who was a software engineer at Facebook. It serves as the view of MVC architecture . It is maintained and developed by Facebook, Instagram, and a community of individual developers and companies. The reaction is only concerned with public management and referring the situation to the DOM , so the creation of reactive applications usually requires the use of additional libraries for routing as well as the operation of certain clients. Let us take a closer look at some important features of React :         Declarative         Simple         Component-based         Support server-side         Extensive         Fast         Easy to learn Why ReactJS?

NoSQL

 It All About NoSQL Databases  What is NoSQL? NoSQL is a non-relational database. It doesn’t need a schema. NoSQL stands for “ Not Only SQL ” or “ NOT SQL ”. NoSQL database is a distributed database system with large database storage and it can store structured, semi-structured, unstructured, and polymorphic data. So, it is a huge advantage for large databases such as Google, Twitter, Facebook. Because they're using terabytes of data. NoSQL can be horizontally scalable when the traffic jams can be handled by adding more servers to the database. So, this database system is very functional and operational with modern technologies. The NoSQL database is mostly open-source. So, anyone can easily use those databases. Why NoSQL? When we using RDBMS to handle massive data volume, system response time is very slow. It makes traffics in servers. To resolve this problem, we need to upgrade our existing hardware. But this is an expensive process. The alternative for this problem we can d...
