Difference between Elasticsearch and MS SQL

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. 2. MS SQL : MS SQL is a relational database management system developed by Microsoft in 1989. It is highly scalable and secure platform for data storage. It offers smart analytics features with high performance and security. The core component of MS SQL server is the SQL server database engine, which controls the data and its processing. It supports ACID properties and guarantee that transactions are processed reliably.
