Elasticsearch vs Oracle

I am a student and my project is about Elastic Stack.
the company I work for is currently using oracle for managing its data.
they want assess Elasticsearch as a replacement.
according to my project success they will consider to transform from Oracle to Elasticsearch.

  1. Does Elasticsearch can replace oracle?
  2. Elasticsearch search performance is faster?
  3. Is it reliable as a primary database?
  4. What are the main advantages of Elasticsearch over oracle? how can I demonstrate them in my code?

please I would love to know the answers

Please do not open multiple threads for the same question.


Looks like Is Elasticsearch as a primary database better than Oracle? is the other conversation.
