Procedural Language vs. Non-procedural Language: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on February 6, 2024
Procedural Language focuses on the steps to solve a problem; commands are executed in sequence. Non-Procedural Language specifies what needs to be done, not how; more about the outcome than steps.

Key Differences

Procedural languages are grounded in the traditional approach of programming, emphasizing a step-by-step method of solving problems. Non-procedural languages, in contrast, are more abstract, focusing on what the end result should be rather than detailing every individual step to get there.

In procedural languages, programmers must provide explicit instructions for every operation. Non-procedural languages, alternatively, allow developers to state their requirements or conditions, and the language's interpreter or compiler figures out the steps to achieve the desired outcome.

Procedural languages are typically more detailed and explicit, making them sometimes more labor-intensive but also clearer in terms of understanding the logic flow. Non-procedural languages, on the other hand, are often more succinct and can be easier to write, but may require more sophisticated understanding of how the language interprets commands.

Examples of procedural languages include C and Java, where developers write code that executes in a specific order. Non-procedural languages, such as SQL and Prolog, allow users to describe what they want to achieve, and the system determines the best way to achieve it.

The choice between procedural and non-procedural languages often depends on the task at hand. Procedural languages are preferred for tasks where control and specificity are key, while non-procedural languages are better suited for tasks involving complex data relationships or where the end goal is known but the path is not.

Procedural Language and Non-procedural Language Definitions

Procedural Language

Requires detailed step-by-step instructions for tasks.
In Java, you define every step to sort a list of numbers.

Non-procedural Language

Focuses on the 'what' rather than the 'how' of problem-solving.
In SQL, you request data without specifying the retrieval process.

Non-procedural Language

Often used in database query languages and AI applications.
In LINQ, you query collections in a declarative manner.

Procedural Language

Operates through a series of procedural calls and routines.
In BASIC, you use subroutines to handle different parts of a program.

Non-procedural Language

Allows specification of desired results, not the steps to get there.
In Prolog, you define facts and rules, and the system infers answers.
