How To Connect Oracle Database from Spring Boot App to perform CRUD Operations | Spring Data JPA

⭐How To Connect Oracle Database from Spring Boot App to perform CRUD Operations | Spring Data JPA⭐
In this example, we are creating crud operations and exposing them through REST APIs so that UI clients can invoke these operations. The demo operations enable the clients to modify the employee records in database with all CRUD Operation (Create , Read, Insert, Update & Delete )Using SpringBoot , Hibernate , JPA , Oracle DB and REST calls with POSTMAN.

The purpose of this example to show how data flows to DB, which make this interaction possible, not covering the complexity in business logic involved in real world applications.
Required Tools we are using for this Program: Java Development Kit (JDK) 17 + Oracle 19c + SQL Developer + Postman + Eclipse IDE 2022
