The distributed database architecture that will be employed for the canteen management's similar canteen on another campus is the client-server architecture.
In the client-server architecture, the database is divided into two main components: the client, which is the user interface or application that interacts with the system, and the server, which is the central repository of data and handles all database operations.
The client applications on both campuses will connect to the central server to access and manipulate the data. This architecture allows for centralized control and management of data, ensuring consistency across both canteens.
Motivation:
1. Scalability: The client-server architecture is highly scalable, allowing for the easy addition of more clients or campuses without impacting the performance of the system. As the canteen management expands to more campuses, they can simply add more client applications while maintaining a single central server.
2. Centralized control: By employing a server as the central repository of data, the canteen management can ensure consistency and integrity of the database. Any changes or updates made on one campus will be immediately reflected in the database, providing a synchronized view of data across all campuses.
3. Security: The client-server architecture allows for centralized control of access rights and security policies. By enforcing access controls at the server level, the canteen management can ensure that only authorized users can access and modify the data. This enhances data security and minimizes the risk of unauthorized access or data breaches.
4. Efficient data management: With a centralized server, the canteen management can efficiently manage and backup the data. They can easily perform routine maintenance tasks, such as backups and updates, on the central server, ensuring the data remains secure and up to date.
Overall, the client-server architecture is well-suited for the canteen management's needs as it provides scalability, centralized control, enhanced security, and efficient data management for their distributed canteen application.
