Define information systems analysis and design. Systems analysis and design is the complex organizational process whereby computer-based information systems are developed and operated.

In addition to application software, the information system includes: ■ ■ ■ ■ ■ The hardware and systems software on which the application software runs. Note that the systems software helps the computer function, whereas the application software helps the user perform tasks such as writing a paper, preparing a spreadsheet, and linking to the Internet. Documentation and training materials, which are materials created by the systems analyst to help employees use the software they’ve helped create.

Developers use visual programming environments, such as Visual Basic, to design the user interfaces for systems that run on client/server platforms. In a client/server environment, some of the software runs on the server, a powerful computer designed to allow many people access to software and data stored on it, and some of the software runs on client machines. Client machines are the PCs you use at your desk at work. The database usually resides on the server. These relationships are shown in Figure 1-7.
