J2EE architecture is a tiered structure that separates an application into different logical components. The main tiers are:
1. Presentation Tier: Handles user interface and user interactions (e.g., web browsers).
2. Business Logic Tier: Contains business rules and logic (e.g., EJBs).
3. Data Tier: Manages data storage and retrieval (e.g., databases).nConnectors, which enable communication between the tiers, are also a part of J2EE architecture.
