Activities
- Field study. Take a visit to a travel agency.
- Identify participants
that are involved in data collection and information technology for the given examples of transaction processing systems that you observe.
- Describe the relationships between participants, data
information and information technology for the given examples of transaction processing systems.
- Diagrammatically represent the given examples of transaction systems using data flow diagrams
- What storing procedures are in place?
- Inquire how storage of digital data in databases and files is carried out.
- How is stored data retrieved to conduct further transaction processing such as printing invoices?
- What system to store paper records of transactions are in place?
- Document your field study, by preparing a report including diagrammatical representations, the steps in the transaction process.
- Identify participants
that are involved in data collection and information technology for the given examples of transaction processing systems that you observe.
- Research. Research two of the following:
- MICR for reading cheques
- ATM
- Barcode readers.
- Describe the operation of the listed hardware and how each is used to collect data for transaction processing.
- Write a long response on the changing nature of work and the effect on participants.
In your response discuss the following points:- Identify jobs that have changed and / or jobs that have been created as a result of transaction processing, and report on the implications of these
changes for participants in the system.
- Discuss alternatives for when the transaction processing system is not available and explain why they need to be periodically tested.
- Identify jobs that have changed and / or jobs that have been created as a result of transaction processing, and report on the implications of these
changes for participants in the system.
- Identify security, bias and accuracy problems that could arise from the actions of participants.
