Before starting with most popular NoSQL databases. You must have to know about <strong>NoSQL databases</strong>. Most of the programmer doesn’t know that it stands for <strong>Not only SQL</strong>. After getting knowledge of NoSQL database, we will jump into <em>Best NoSQL databases</em> for the 2019 year and we also see Cassandra vs MongoDB vs HBase.
Before starting with most popular NoSQL databases. You must have to know about NoSQL databases. Most of the programmer doesn’t know that it stands for Not only SQL. After getting knowledge of NoSQL database, we will jump into Best NoSQL databases for the 2019 year and we also see Cassandra vs MongoDB vs HBase.
NoSQL databases (additionally called Not Only SQL Databases) are non-relationaldatabase systems used for Storing and Retrieving data. These days NoSQL Databases are vigorously utilized as a part of real-time web applications. NoSQL databases can likewise be said as Big Data databases or Cloud databases. NoSQL Databases are quicker in contrast to SQL Databases and thus NoSQL Databases are utilized as a part of a Big Data application. Before utilizing any specific NoSQL Database you ought to check its component first on the grounds that each NoSQL Database has it claim set of functionalities. Now, we will go to Most popular NoSQL databases and Best NoSQL Database for 2019 and 2020 year.
It is an open source NoSQL database which is document-oriented. MongoDB uses JSON like documents to store any data. It is written in C++.
It was developed at Facebook for inbox search. Cassandra is a distributed data storage system for handling very large amounts of structured data.
Redis is the most famous key-value store. Redis is composed in C language. It is authorized under BSD.
It is a distributed and non-relational database which is designed for the BigTable database by Google.
Neo4j is referred to as a native graph database because it effectively implements the property graph model down to the storage level.
Oracle NoSQL Database implements a map from user-defined keys to opaque data items.
DynamoDB uses a NoSQL database model, which is nonrelational, allowing documents, graphs and columnar among its data models.
Couchbase Server is a NoSQL document database for interactive web applications. It has a flexible data model, is easily scalable, provides consistent high performance.
It is an open source, high-performance, distributed memory caching system intended to speed up dynamic web applications by reducing the database load.
Cassandra was developed at Facebook for inbox search. Cassandra is a distributed data storage system for handling very large amounts of structured data. Generally, these data are spread out across many commodity servers. You can also add storage capacity of your data keeping your service online and you can do this task easily. As all the nodes in a cluster are same, there is no complex configuration to deal with. Cassandra is written in Java. Cassandra Query Language (CQL) is a SQL-like language for querying Cassandra Database. As a result, Cassandra stands 2nd in best open source databases. Cassandra is being used by some of the biggest companies such as Facebook, Twitter, Cisco, Rackspace, eBay, Twitter, Netflix, and more.
Redis is a key-value store. Furthermore, it is the most famous key-value store. Redis has support for some C++, PHP, Ruby, Python, Perl, Scala and so forth. Redis is composed in C language. Furthermore, it is authorized under BSD.
HBase is a distributed and non-relational database which is designed for the BigTable database by Google. One of the main goals of HBase is to host Billions of rows Xmillions of columns. You can add servers anytime to increase capacity. And multiple master nodes will ensure high availability of your data. HBase is composed in Java 8. It’s authorized under Apache. Hbase accompanies simple to utilize Java API for customer access also.
Neo4j is referred to as a native graph database because it effectively implements the property graph model down to the storage level. This means that the data is stored exactly as you whiteboard it, and the database uses pointers to navigate and traverse the graph. Neo4j has both a Community Edition and Enterprise Edition of the database. The Enterprise Edition includes all that Community Edition has to offer, plus extra enterprise requirements such as backups, clustering, and failover abilities.
Oracle just started NoSQL database with Oracle NoSQL. It’s becoming popular in the year 2018. It less popular compare to MongoDB and Casandra databases. Oracle NoSQL Database implements a map from user-defined keys to opaque data items. Although it records internal version numbers for key/value pairs, it only maintains the single latest version in the store. The version of Oracle, 12c, is designed for the cloud and can be hosted on a single server or multiple servers, and it enables the management of databases holding billions of records. Some of the features of the latest version of Oracle include a grid framework and the use of both physical and logical structures. Oracle Database 18c now provides customers with a high-performance, reliable and secure platform to easily and cost-effectively modernize their transactional and analytical workloads either in the Cloud, or on-premises or in a Hybrid Cloud configuration.
DynamoDB uses a NoSQL database model, which is nonrelational, allowing documents, graphs and columnar among its data models. Each DynamoDB query is executed by a primary key identified by the user, which uniquely identifies each item. It also relieves the customers from the burden of operating and scaling a distributed database. Hence, hardware provisioning, setup, configuration, replication, software patching, cluster scaling, etc. is managed by Amazon.
The focus is on the ease of use, embracing the web. It is a NoSQL document store database. Couchbase Server is a NoSQL document database for interactive web applications. It has a flexible data model, is easily scalable, provides consistent high performance. Couchbase Server, JSON documents are used to represent application objects and the relationships between objects.
Memcached is an open source, high-performance, distributed memory caching system intended to speed up dynamic web applications by reducing the database load. It is a key-value dictionary of strings, objects, etc., stored in the memory, resulting from database calls, API calls, or page rendering. It is now being used by Netlog, Facebook, Flickr, Wikipedia, Twitter, and YouTube among others.
Before ending list for NoSQL database. I must recommend preparing for Database interview -> Most popular quires for databases. We have recently been taking a survey from different programmers who are available on google plus social media for all SQL and NoSQL databases. Here we have seen the most popular database with its features, pros, and cons. Now you can decide which one is best for your project.
Learn how to design and plan a database for beginners. This database design course will help you understand database concepts and give you a deeper grasp of database design. Database design is the organisation of data according to a database model. The designer determines what data must be stored and how the data elements interrelate. With this information, they can begin to fit the data to the database model.
This video on 'Python Database Connection', you will learn how to establish a connection between Python and MySQL DB and perform CRUD operations on it.
