Layer (top to bottom)
Information Retrieval and Modification
User Communications / Authentication and Authorization
Transaction Management / Database
User Interface
Function
Handles all interaction with the user; implemented using a web browser in modern systems
Manages user login, role checking, form and menu management, and data validation
Implements application-specific logic for accessing and updating the database; includes security, data import/export, and report generation
Provides persistent data storage, transaction management, and data integrity using a commercial DBMS
Correct Answer
(1) User Interface,Handles all interaction with the user; implemented using a web browser in modern systems
(2) User Communications / Authentication and Authorization,Manages user login, role checking, form and menu management, and data validation
(3) Information Retrieval and Modification,Implements application-specific logic for accessing and updating the database; includes security, data import/export, and report generation
(4) Transaction Management / Database,Provides persistent data storage, transaction management, and data integrity using a commercial DBMS
Explanation
The four-layer information system architecture: top layer - User Interface (web browser); second layer - User Communications, Authentication and Authorization (login, role checking, forms, validation); third layer - Information Retrieval and Modification (application logic, security management, import/export, reports); bottom layer - Transaction Management and Database (commercial DBMS for persistent storage).
