Students learn to:

1.Characteristics of transaction processing systems

(a)Describe a TPS as information systems that collect, store, modify and retrieve transactions of an organisation.

(b)Outline characteristics of a TPS—rapid response, reliability, inflexibility, controlled processing.

(c)Identify, describe and use batch transaction processing—advantages and disadvantages.

(d)Identify, describe and use real-time transaction processing—concurrency, atomicity, advantages and disadvantages.

(e)Compare and contrast batch and real-time transaction processing.

(f)Understand the significance of data validationtransaction initiation, field checking.

(g)Describe the historical significance of transaction processing systems.

(h)Assesses the work routine of a manual transaction system.

2.Examples of transaction processing systems

(a)Describe the components of a transaction processing system—users, participants, people.

(b)Describe real-time transaction processing systems in terms of participants, data/information and information technology:

reservation systems.

POS terminals.

library loan system.

(c) Describe batch transaction processing systems in terms of participants, data/information and information technology:

cheque clearance.

bill generation.

credit card sales transactions.

3.Storing and retrieving

(a)Describe the storage of data into databases and fileshierarchical database, network database, relational database, master file, transaction file, report file, work file, programs file.

(b)Understand a data warehouse—data that is consolidated, subject-oriented, historical, read-only.

(c)Select and apply backup procedures—recovery, journal, checkpoint, backward recovery, forward recovery, magnetic tape, grandfather-father-son, partial backup.

(d)Update in batch—sequential access, information technology.

(e)Update in real time—direct access, information technology.

4.Other information processes

(a)Describe collecting data for a TPS—MICR, ATM, barcode readers, paper forms, on-screen forms, Web forms.

(b)Design and justify paper forms to collect data for batch processing.

(c)Design user-friendly screens for on-line data collection.

(d)Describe analysing data for a TPS—decision support systems, data mining, management information systems.

5.Issues related to transaction processing systems

(a)Identify the issue of nature of work—automation of jobs, people as participants.

(b)Understand the need for non-computer procedures to deal with transactions when the computer is not available.

(c)Identify the issue of bias.

(d)Describe the importance of data in transaction processing—data security, data accuracy, data integrity.

(e)Describe control in transaction processing.
