1. Amazon Neptune :
Amazon Neptune is a fast, reliable graph database built for the cloud product by Amazon.com. It is part of Amazon Web Services (AWS). It was announced on November 29, 2017. It supports both the open-source Apache TinkerPop Gremlin graph traversal language. It allows the user to encrypt databases using keys created through AWS Key Management Service....
Functional dependency in DBMS is an important concept that describes the relationship between attributes (columns) in a table. It shows that the value of one attribute determines the other. In this article, we will learn about functional dependencies and their types....
Multi-Version Concurrency Control (MVCC) is a database optimization method, that makes redundant copies of records to allow for safe concurrent reading and updating of data. DBMS reads and writes are not blocked by one another while using MVCC. A technique called concurrency control keeps concurrent processes running to avoid read/write conflicts or other irregularities in a database....
1. RDBMS :
RDBMS stands for Relational Database Management Systems. It is most popular database. In it data is store in the form of row that is in the form of tuple. It contain numbers of table and data can be easily access because data is store in the table. This Model was proposed by E.F....
In this article, we are going to discuss Cassandra and Relational overview in which we will cover and able to learn how Cassandra differentiates the Relational overview. Let’s discuss one by one....
1. Elasticsearch :
Elasticsearch is a distributed search and analytics engine.It is open source and can be used for all types of data.It is implemented in Java programming language and supports all operating systems having java virtual machines (J.V.M).It is the main component of Elastic Stack, which is a open source application for data analysis and visualization. It has high scalability and the speed of performing a action is also high which makes it a easy and fast tool for data analysis, processing and visualization....

1. PostgreSQL :
PostgreSQL is a powerful, open-source Object-relational database system. It provides good performance with low maintenance efforts because of its high stability. PostgreSQL was the first DBMS that implemented multi-version concurrency control (MVCC) feature....
1. SQLite : SQLite is a software library that provides a relational database management system (RDBMS). It was designed by D. Richard Hipp in August 2000. The design goals of SQLite were to allow the program to be operated without installing a database management system (DBMS) or requiring a database administrator. 2. Cassandra : Cassandra is a free and open-source, distributed, wide column store, NoSQL database management system. It was developed by Apache Software Foundation and initially released in July 2008. Cassandra is designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Difference between SQLite and Cassandra :...
Vertica is unique in many ways, one of which can be seen in its data storage model. Vertica uses two distinct structures for storing data: WOS storage (Write Optimized Row Storage), and ROS storage (Read Optimized Column Storage). These are explained as following below....
