Deklaratiiv

Deklaratiiv refers to a programming paradigm or style of writing computer programs. Instead of explicitly stating the step-by-step instructions a computer should follow to achieve a result, a deklaratiiv program describes the desired outcome or logic. The system then figures out how to implement that outcome. This contrasts with imperative programming, where programmers must specify the control flow and sequence of operations.

In a deklaratiiv approach, the focus is on "what" needs to be done rather than "how" it should be done. Examples of deklaratiiv languages and systems include SQL for database queries, HTML for web page structure, and configuration management tools like Ansible or Terraform. In SQL, you declare the data you want to retrieve, and the database engine optimizes the process of fetching it. Similarly, in HTML, you declare the elements of a webpage, and the browser renders them accordingly.

The benefits of deklaratiiv programming often include increased readability, reduced complexity, and easier maintenance. Because the programmer is not bogged down with low-level implementation details, the code can be more abstract and easier to understand. This abstraction can also lead to more robust and secure software, as the underlying system handles the intricacies of execution. While imperative programming remains dominant in many areas, deklaratiiv approaches are gaining traction for their ability to simplify complex tasks and improve developer productivity.
