People ResourcesPeople Resources

End users-accountants, salesperson, engineers, clerks,

customers, or managers.

includes all sets of information processinginstructions.

This generic concept of software includes notonly the sets of operating instructions calledprograms, which direct and control computerhardware,

but also the sets of information processinginstructions needed by people, calledprocedures

Software ResourcesSoftware Resources

System software, such as an operating systemprogram, which controls and supports theoperations of a computer system.

Application software, which are programs thatdirect processing for a particular use ofcomputers by end users. Examples are a salesanalysis program, a payroll program, and a word

processing program. Procedures, which are operating instructions for

the people, who will use an information system.Examples are instructions for filling out a paperform or using a software package.

Data ResourcesData Resources

Data is raw material of information systems, database withcriteria: Comprehensiveness means, that all the data about the

subject are actually present in the database. Non-redundancy means, that each individual piece of

data exists only once in the database. Appropriate structure means, that the data are stored

in such a way as to minimize the cost of expected

processing and storage. The data resources of IS are typically organized into: Processed and organized data-Databases Knowledge in a variety of forms such as facts, rules, and

case examples about successful business practices.

output, and storage activities. This feedback must be monitored and

evaluated to determine if the system ismeeting established performance

standards. Then appropriate system activities

must be adjusted so that proper

information products are produced for
