Adatkötés

Adatkötés is a Hungarian term that translates to data binding in English. It refers to a programming technique that establishes a connection between two data sources, typically a user interface element and a data model. When the data in the model changes, the user interface automatically updates to reflect these changes, and vice-versa, when the user interacts with the interface and modifies the data, the model is updated accordingly. This bidirectional synchronization simplifies the development of dynamic and interactive applications by reducing the need for manual synchronization code.

The concept of datakötés is prevalent in various programming paradigms, particularly in modern front-end web development frameworks such as React, Angular, and Vue.js. These frameworks often provide declarative ways to implement datakötés, allowing developers to define the relationships between UI elements and data with less imperative code. For example, in a form, a text input field can be datakötés to a string variable in the application's state. Typing into the input field updates the string variable, and if the string variable is programmatically changed, the text displayed in the input field will also update.

This mechanism significantly improves developer productivity and leads to more robust and maintainable applications. By automating the process of keeping the UI and data in sync, datakötés minimizes the potential for errors that can arise from manual data manipulation. It allows developers to focus more on application logic and user experience rather than on the intricacies of data synchronization. The efficiency and ease of use provided by datakötés have made it a fundamental aspect of contemporary software development.
