With introduction of some of the best nosql databases in the market , gone are those days when developers adopted the methodology of one database per application . Now even single app could have plural number of databases . All thanks to these key value databases. Before moving on to the list of nosql databases , lets discuss once what exactly they are .
[su_note note_color=â#FFF9C4âł]Well it stands for Not only SQL . According to Wikipedia , a NoSQL (originally referring to ânon SQLâ or ânon relationalâ) database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases[/su_note]
A database is basically a collection of information which is well organized and can easily be accessed , updated and managed. Taking a step ahead, NoSQL database are a non-relational database systems used of storing and retrieving data.
If we look at the recent trends , these key value database have gained a lot of popularity. They also come handy as they help in real time web synchronizations.
NoSQL databases are relatively very faster as compared to SQL dBs. Therefore they come very handy when you have a Big Data or cloud based application to implement.
Each NoSQL database has its own capabilities and its own complications. So before we pick one for our application, we have to make sure that it suits our requirements. So have a look at our guide for Best NoSQL databases 2019 edition.
If you are interested in stats, you can have a look over these recent trend charts from a recent study , as mentioned on db-engines , trending and best NoSQL database guide .
Since the analytical studies have shown such order, weâll also go in detail based on these results only. However, point to be noted here is this order doesnât actually mean that this order will be same forever.
[su_note note_color=â#FFF9C4âł]Your preference for choice of best Nosql databases may change based on your scenario of usage and technology you want to club with.[/su_note]
If you are work with python and machine learning, i would suggest you to kindly have a look at Best Python IDE for Machine Learning guide.
Moving over to the list of nosql databases along with comparisons , here is my analysis :
This Open Source NoSQL database is i can say most user friendly and secure. Its highly scalable options with vast ecosystem of availability among partners makes it even more likely .
MongoDB is document oriented NoSQL database which uses JSON like structure documents to store any data. It has been written in C++ , and hence accounts for fast transactions also.
The cost at which its available makes it even more competitive to Oracleâs MySQL. It entered the database as a service in market during 2016 with MongoDB Atlas.
It also offers MongoDB stitch which helps developers integrate third party services into their application without need of any of those boilerplate code to compromise on the app security.
MongodB can be utilized as an filesystem also. MongoDBâs query language is javascript, which makes it even more easy to use. People really enjoying sharding, gridFS, advanced text searching, map-reduce features , which can be achieved with MongoDB.
Because of such variety of features , MongoDB has made to first place among this list of nosql databases .

Firebase database is one of those freemium databases out there in market. But the point is even though it offers a paid service, i personally like it for many reasons. Therefore it got entry in my best NoSQL databases list .
Firebase is a NoSQL cloud database . A NoSQL database provides a mechanism for storage and retrieval of data which is not plain tabular form of data. Data is stored as JSON and synchronized in realtime to every connected client.
In short Firebase is a platform which allows us to build web and mobile applications , without server side programming language.
You can store and retrieve users data on its real-time database which sync data among users data in no time.
I love its real time database personally. I am using it for one of my project. Its really fast and secure.
Because of all these features , i personally think it is by far best nosql database for node js or front end applications. It removes one application layer completely.

IBM dB2 is a relational Database Management System. It can be used for storing, retrieving, analyzing the data efficiently.
With the assistance of OOPs features and non-relational structures with XML, DB2 product is quite extensive. It has various features over another features which makes it usable over other RDBMS.
DB2 is one of the most âmatureâ Relational Databases (along with Oracle). Which also means that, it has been used in the field for a long time by a lot of people. That gives it lots of âprosâ but maybe a few âconsâ as well.
I have observed that it is one of the best nosql database for python based applications or products.

Apache Cassandra is one of my favourite among this list of nosql databases. Many reasons contribute to same.
Itâs an open source , distributed key value NoSQL DBMS. It was first a facebook project mainly for the purpose of inbox search. Later it was released and made open source project.
Itâs available in two versions : DataStax Community Edition and a commercial edition.
It was created for online applications that require fast performance and no downtime. Whereas it was totally built for handling very large amounts of data. But the main purpose of the same was to assure high availablity.
It works on Cassandra Query Language (CQL) . CQL is a SQL-like language for querying Cassandra Database. Cassandra has been purely written in JAVA.
Cassandra is being used by some of the biggest tech companies such as Facebook, Twitter, eBay, Twitter, Netflix, Cisco and more.

âDead-Simple Configuration and Scary-Fast Performanceâ is what one of the reviews read for Redis. it is basically used for cache management and that is how it has been recommended to use always.
Redis cannot be claimed as a permanent back end data storage solution but it is best at what it is supposed to do. That is cache management.
Due to its fast performance and key value structure , it is so very easy to use. It supports almost all languages. It is widely used with C++, PHP, Ruby, Python, Perl, Scala and many more.
Itâs been written in C++ . By far it is the fastest NoSQL databases. So due to its fast transactions , it is considered as best nosql database for analytics based products caching and usage.
I used Redis recently in one of my project and created this guide : How to deploy Redis on Heroku

Since HBase is a NoSQL database , it is open source and can store big data. We can store any structured, semi-structured and unstructured data very easily.
One other major benefit of using this fast NoSQL database , it is a columnar database so there is no need to specify any schema. Trust me it is one of the best nosql database for big data applications.
HBase stores the big data in a very good manner and it is horizontally scalable. There are many other security tools available which could be easily integrated along, like Atlas and Ranger.
It helps in querying the records much faster than any other NoSQL databases.

If you are looking for a graph database solution then Neo4j should be your choice . It is the most robust and easiest solution out there in the market.
The community version is free and the community support around Neo4j is really good. However you may have to pay for the premium features. Performance of this database is extremely fast.
Neo4j can be used to store data that have tree kind of relationships. It addressees the problems of storing data which have multiple relationship surprisingly amazing way.
â Are you ready for the best Graph Database in town? â â read one of the reviews on Trust radius.
It uses CYPHER as the query language. It stores data similar way as you would draw it on whiteboard.
If you are a python user then this is for sure one of the best nosql database for python .

If you are a mobile developer , maybe youâd be interested in having a look at my most starred Github project : MagicPrint â ECommerce App Android Open Source Project with Code Download
DynamoDB is also one of those NoSQL databases which use non relational database . It can be use to used to store any kind of data structure be it graph, columnar or documents .
DynamoDB helps support the very random access patterns, not matter what may be the inputs. With DynamoDB, we can automatically scale to whatever needs we want to cater .
Unlike traditional SQL or Relational databases, DynamoDB is totally designed to have all relevant data within one single object.
Whereas DynamoDB does not have join table support, nor does it support complex searches. There is no ârollbackâ option too.
Itâs JSON structure makes it best nosql database for node js or any other javascript based application.

All these days Oracle was backing up SQL databases. However, breaking the trend Oracle recently launched Oracle NoSQL database. It started becoming popular inthe year 2019 . Even though it is less popular compared to MongoDB or Cassandra databases but it serves the purpose correctly.
Oracle NoSQL Database implements a map for user-defined keys to keep opaque data items. It keeps only one latest version of records and doesnât really implements versioning. However it generates it own internal version and you canât provide them.
It supports both physical and logical structures. It could be one of those best nosql database for big data , you never know.
I have seen it getting popular only among Enterprises. Small businesses have seriously not considered it as of now.

So last on our best nosql databases list is Memcached. I would not say itâs a full fledged dB , but rather a database load sharing mechanism.
It is usually used as an open source, high-performance, distributed memory caching system, totally intended to speed up dynamic web applications. It is a key value database stored in memory.
Memcached is somewhat similar to REDIS.
It is being used by Facebook, Flickr, Wikipedia, Twitter, YouTube and others.
