Quizplus · Accepted Answer

In a three-tier client-server database architecture, the third tier can be either a middleware server or an application server. Both options are valid for handling business logic and data processing between the client interface and the database server. The role of the middleware server is primarily to provide connectivity and data transformation services, while the application server offers more advanced processing and logic capabilities, such as executing complex queries, managing transactions, and integrating with external systems. The choice between middleware and application server depends on the specific requirements and complexity of the application.
