Declarative Programming Paradigm

Declarative programming is a paradigm that emphasizes describing the desired outcome rather than specifying the step-by-step process to achieve it. Instead of instructing the computer on "how to do it," you focus on "what to do."

Key Characteristics

- **Outcome-oriented:** Define the result or behavior you want.

- **Rules and expressions:** Provide a set of rules, constraints, or expressions.

- **Interpreter/Compiler:** The language interpreter or compiler determines the execution steps.

## Examples

### SQL (Structured Query Language)


-- Declarative query to retrieve data

SELECT column1, column2 FROM table WHERE condition;
