Every web application needs to save and update data that is accessible via HTTP. This data must be secured. The backend, on the other hand, might be more challenging to get started with since seeing the effects of your work is more challenging. It's more command-line-centric, and it's also more reliant on jargon: everyone can figure out what a paragraph tag does, but GET and POST requests, though essential to backend development and the web, aren't as simple to grasp. We'll go over what back-end development is all about, as well as back-end programming methodologies, in detail in this post. Java with decades of history in professional enterprise development is great choice for any application secure stack. Kotlin similar to Java is used for implementation. Spring within Java ecosystem makes building resources secure. In this paper, we will be developing a backend service with Spring Data JPA to perform CRUD operations with PostgreSQL using Kotlin.

Spring Data JPA, PostgreSQL, Kotlin.
