Difference between Elasticsearch and IBM DB2

1. Elasticsearch :
It 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. IBM DB2 :
It is a relational database which was developed by IBM in 1983. It is considered as a family of database management products which are build for AI. It has enhanced capabilities for performing transactions. It works on the principle of ACID and has high flexibility and performance. It has efficient backup facilities and is considered very secure. It is extremely reliable and is supported by Linux, Unix and Windows operating systems. It has a commercial license and has high scalability.
