Programming architecture ensures reliability and scalability. The Model-View-Controller (MVC) pattern helps in organizing code into three components: model (data and logic), view (presentation), and controller (user interaction). Applying MVC in MQL5 for table models enhances clarity and maintenance.

Create classes for table elements—cells, rows, and models—utilizing linked lists for efficient data storage. The CList class in MQL5 facilitates moving and managing rows and cells dynamically, crucial for file operations. Implement an inherited CList class to enable file-based operations and object creation through the CreateElement() method. This approach allows the architecture to adapt as applications grow, ensuring structure and flexibility.
