Exam 10: System Architecture

A three-tier design includes a middle layer between the client and server that processes the client requests and translates them into data access commands that can be understood and carried out by the server.

An information system includes ____________________, which are programs that handle the input, manage the processing logic, and provide the required output.

In addition to centralized data processing, the earliest systems performed all data input and output at a central location, often called a(n) ____________________.

The advantage of the application logic layer is that a three-tier design enhances overall performance by reducing the data server's workload.
