1. What is meant by the application deployment environment? Why is it important in the consideration of a development approach?

The application deployment environment consists of the computer hardware (platforms) and operating systems that will support the application program. The new application system may have to meet special design requirements to conform to the restrictions of the operating system and the equipment.

2. List and briefly describe the characteristics that an analyst examines when choosing or defining the deployment environment.

Analysts consider the configuration of computer equipment, operating systems, and networks that will exist when the new application system is deployed.

3. Describe the relationship between the application deployment and development environments.

The development environment consists of the programming languages, CASE (computer-assisted software engineering) tools, and other software used to develop application software.

The application deployment environment, particularly the operating system, DBMS, and distributed software standard, usually limits the choices that are available for the development environment.

Companies prefer certain languages for system development, and their analysts are familiar with the features of these languages.
