Introduction

Wendy McIntyre HNC Computing Assessment 3 Outcome 2 a, b, d The following information outlines all of the generic components of an information system and how and who may utilise a typical academic and results system. The information flows within this system will be outlined with the aid of an annotated diagram. An information system consists of the following components. Data Data is one of the most crucial components of an information system. It is collected and transformed into valuable information. The purpose of collecting data is to create value for the various users of a system. Personnel Personnel are the users of an information system, without them the data and information would not exist; therefore value would not be created. Manual Procedures Manual procedures are required to be followed by the users of an information system; this regulates the sequence and method by which data is entered and stored. Hardware This refers to all the physical devices installed i.e. ...read more.

Clients/Users of Information Systems Clients of information systems can be either internal or external to the organisation. Internal Clients include; * Management at all levels * Users at all levels People who are employed within an organisation generally want to know how that organisation is performing for example; Managers at all levels may want to use the information for planning, control and decision making. External Clients may include; * Government agencies (for legal or tax reasons) * Competitors, in order to monitor industry performance * Customers, suppliers and perhaps the general public, if for a legitimate purpose e.g. a student wishing to access an academic and results system may be viewed as an external customer. * Stakeholders - in order to monitor investment and make future decisions based on that investment. Described below is the use made by four internal and two external clients of information, contained in a typical academic results and records system. Internal Clients Admissions Office - would use the information system to pull records on student identity and demographics - to allow mailing of examination results - accessing course descriptions and entry requirements. ...read more.

Conclusion

another; like for instance the information collected at the admissions office, may then travel through the system to other departments for e.g. to lecturers, in order to advise of class numbers. External flows - this is information with flows from inside the organisation to an element out with the organisation e.g. to the external bodies; or to the student accessing examination results; or on-line course materials from home. This process may also be reversed, allowing an external client to move information to within an organisation, although this is not displayed in the diagram above. Electronic Based and Hardcopy Information - electronic information is information which is sent which is sent via e-mail in the form of a memo, for example the admissions office may wish to highlight the fact that a student with special needs has enrolled on a course, therefore may send an e-mail to inform the department of specific requirements. A hardcopy on the other hand would be information transferred by foot, in the form of a report, or perhaps mailed paper copies of examination results. ...read more.
