MVC, DCI, and lookups like the NetBeans APIs allow for modular and adaptable applications. MVC separates concerns but ties view and controller to the model. DCI focuses on object interactions and morphing objects to provide different contexts. The NetBeans lookup system allows objects to dynamically adapt interfaces and be discovered through queries, supporting modularity. Future application architectures may increasingly use annotations to define actions and controls in a more modular way.
