MVC Architecture
Clean separation between Model, View, and Controller components
Architecture Highlights
The application is structured into three main components:- Model (
Model.java) — Handles all database operations including connection management, query execution, and metadata retrieval - View (
View.java,SqlEditorView.java) — Provides the graphical user interface with custom styling and event handling - Controller (
Controller.java) — Manages interaction between Model and View using SwingWorker for asynchronous operations
