Question

What is the declarative language to manipulate data in a relational database.

Answer 1

There are 4 types of languages:

1. Procedural

2. Declarative

3. Object-oriented

4. Functional

Declarative query languages let users express what data to retrieve, letting the engine underneath take care of seamlessly retrieving it. They function in a more general manner and involve giving broad instructions about what task is to be completed, rather than the specifics on how to complete it. They deal with the results rather than the process, focusing less on the finer details of each task.

Some well-known general declarative programming languages include Ruby, R and Haskell. SQL (Structured Query Language) is a declarative query language and is the industry standard for relational databases.
