Information can be collected in different ways e.g. paper, surveys, stock taking, data capture forms in databases.

E.g. a tennis club can create a form on their website that allows users to apply for membership and fill in key data such as their name, address and telephone number.

48
Q

storage 2.4

Data storage

A
  • data must be stored in a secure and easily-retrievable medium. e.g. paper, magnetic, optical and cloud. Data is most conveniently stored in a database so information can be added, removed or updated
  • must be stored securely to protect against loss, accidental or via hacking/corruption. Sensitive data should be encrypted so it cant be viewed or altered by others unless they have permission. Information should also be backed up in case data is lost.

E.g. the tennis club can store data in a database using cloud storage as soon as a new member enters their information. Using cloud storage allows the tennis club to access that information from multiple access points and they will only pay for the mount of storage that they need and use.

49
Q
A
50
Q

manipulating and processing 2.4

information management

A
  • After collection and storage, data must be processed so that its ready for analysis. Data can be exported to other software e.g. from a database to spreadsheets so it can be manipulated, sorted and visualised. Graphs and carts can be created on data in a spreadsheet so that patterns and trends are easier to identify.

E.g. member information in the tennis club can be exported to spreadsheet software that then allows for graph/chart creation using specific values, such as membership expiry date or membership type.

51
Q

analysis 2.4

A
  • To analyse the data is to see what can be learned from it, so important decisions can be made.
    • E.g. analysing the charts made in the processing stage will allow the tennis club to identify hey patterns. For example they could see when most members sign up in august, a sale on membership can be created at this time to entice new members. Or is most members travel in from a certain area of town a bus system might be set uo to help those members travel in more often.
