These differences impact maintainability, reusability, and scalability.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Approach (Procedural vs. Object-Centric)<\/strong><br>Function-oriented design follows a <strong>procedural<\/strong> approach, meaning the system is divided into functions that perform specific tasks. It emphasizes breaking down the system into a sequence of computational steps. For example, in a banking system, a function like <code>calculateInterest()<\/code> might be responsible for computing interest separately from functions handling deposits or withdrawals. In contrast, object-oriented design revolves around <strong>objects<\/strong>, which bundle data and related behavior. Instead of standalone functions, OOD creates classes representing real-world entities, such as a <code>BankAccount<\/code> class containing attributes (<code>balance<\/code>, <code>accountNumber<\/code>) and methods (<code>deposit()<\/code>, <code>withdraw()<\/code>, <code>calculateInterest()<\/code>). This makes it easier to model complex systems naturally and extend functionality.<\/li>\n\n\n\n<li><strong>Data Handling (Global vs. Encapsulation)<\/strong><br>In function-oriented design, data is often stored in global structures or passed between functions. This makes the data vulnerable to unintended modifications, leading to errors and debugging challenges. For example, multiple functions modifying a shared <code>customerBalance<\/code> variable might introduce inconsistencies. Object-oriented design promotes <strong>encapsulation<\/strong>, where data is <strong>hidden<\/strong> within objects and only accessible through predefined methods. This safeguards the integrity of the data and enforces controlled access. For instance, a <code>BankAccount<\/code> object only allows balance updates through its <code>deposit()<\/code> or <code>withdraw()<\/code> methods, ensuring consistency and security.<\/li>\n<\/ol>\n\n\n\n<p>Thus, object-oriented design offers greater modularity, reusability, and security, making it preferable for large-scale and maintainable software systems.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Image Generation Request<\/h3>\n\n\n\n<p>The image should depict a <strong>side-by-side comparison<\/strong> of function-oriented and object-oriented design with diagrams illustrating function calls in FOD and object interactions in OOD.<\/p>\n\n\n\n<p>Here is the image comparing Function-Oriented Design and Object-Oriented Design.
