Introduction to NoSQL Databases List
The NoSQL database is a non-conceptual database in which it can reserve the data in a different way rather than relational tables. It can supply a process for repository and recovery of facts that is customized it means other than the tabular form which can be used in relational tables. It has various types of databases such as document database can able to reserve the data in a document like JSON object, key-value databases are the uncomplicated database where all product contains key and values, wide-column stores can reserve the data in tables, rows, and dynamic columns.
Top NoSQL Databases List
Let us discuss the topmost NoSQL database list, in which they are MongoDB, Cassandra, Elasticsearch, Amazon DynamoDB, HBase, etc.,
1. MongoDB:
It is a document-based database in which it is a cross-platform and document-based database, and that database can be used most of the time in many organizations, hence it can reserve the document in JSON objects, near about 3400 organizations are using MongoDB in its tech store, this database has been created by MongoDB inc, it can work with the developers’ mind how they think and how they code a powerful query.
If we are trying to combine tons of various data sources then MongoDB is the best option to be used for it because it will give a single unite perspective of the data, and also if we are looking forward to reading and writing huge operations from our application then at that time this database is also useful, so we do not need to worry about our data which may have been lost in the server collision, we can able to use this database in just a few clicks for reserving so that this database is called as the clickstream data database and we can able to use it for customer communicative survey.
2. Cassandra:
It is an open-source scattered database system and at first, it was developed by Facebook, it is extensively available and completely portable, it can able to operate petabytes of information and it can also able to handle thousands of synchronic requests for every second, near about 400 companies are using this database such as Facebook, Instagram, Netflix, Spotify, Coursera, etc.
If we have more use cases for reading and less for writing then this database is helpful, and there is also a case when we require better accessibility than stability then this database we can use for example for social networking websites but it can be useful for banking websites, in this database we need a fewer number of joins and aggregations in our queries to the databases, and also it can be useful for health trackers, weather forecasting, tracking of orders in such cases we can use the Cassandra databases.
3. Elasticsearch:
This is also an open-source, scattered NoSQL database system in which it is portable, modern, and compatible, it is based on Apache Lucene and we can label it as Analytics Engine because it can effortlessly analyze, reserve, and find out lots of data if we have use case having full-text search then this database is the best option for our organization, it also allows searching with indistinct complement, near about 3000 organizations are using this database in their organization.
If we have a use case having full-text search then this database will be best for it, in another case if we have a use case having chatbots in such cases that can have more chances of spelling mistakes hence it can sort out most of the doubt, so it has the in-built feature of fuzzy matching so that will help, also this database can help in reserving huge data and examine it.
4. Amazon DynamoDB:
This is a serverless and scattered database which is totally managed, it has key-value paired, and it was designed by Amazon which is highly reliable, but it is not open-source, it is mainly designed for running high-performance applications at any scale, it can able to handle 10 trillion requests for one day, near about 700 organizations are using this database in their organization like for the same best applications.
If we require to handle a very large number of queries in an easy key-value query then the DynamoDB is the best option for it, and also if we have to work with OLTP work such as online ticket booking or banking at where we want data to be highly available then in such cases this database is best suits, this database can provide in-built security, and it can also take the constant backups, it has in-memory caching and also it can have data export tools.
5. HBase:
It is open-source and it is a highly reliable and column-oriented non-relational database system and it can give big table proficiency for Hadoop, it is a scattered database system, this database has been written in Java which can be a part of the Apache Software Foundation’s project of Apache Hadoop so that it can use an Apache HBase, and it can be run on top of the Hadoop Distributed File System, near about 70 organizations are using this database like Hike, Pinterest, and HubSpot, just now it has released its 1.0 version after so many years of development.
This database can process petabytes of data, when we have a small volume of data then they will not get the result as we want, if in our use case we want random and real-time access to the data then this database will be the best option for it, and if we want to reserve real-time messages for more people in a simple way then also this database will helpful.
Conclusion
In this article, we conclude that the NoSQL database is a non-relational database in which it does not have the relationship between data and the list of it has top five databases which we have discussed above, so this article will help to understand the concept of NoSQL databases list.
