• Data is the raw material entered into an information system. • If the data collected is meaningless, then the information will have no use either. [Garbage in = garbage out (GIGO)] • Organisations need to ensure that appropriate data is available at the time of processing.
• Data will be appropriate if it is: • relevant – useful to the purpose of the information system • accurate – collected from a dependable source and entered without errors • timely – current, and kept up-to-date • secure – protected from deliberate and accidental damage or loss • When data is entered into an information system it is organised into different data types.
• Data types include: • images • audio • video • text • numbers • Information is an important factor in an organisation’s success.
• Information will be valuable if it is: • relevant • accurate • timely • organised • cost-effective
