What ACCTING 2503 covers

The course runs as eleven building blocks, moving from what an accounting information system is, through transaction processing, controls and systems development, to databases, REA modelling, XBRL reporting and hands-on Power BI analytics.

01

An Overview of Accounting Information Systems

What an AIS is · data vs information · the value chain · business processes & transaction cycles · how an AIS adds value
02

Transaction Processing, ERP Systems & System Documentation

The data processing cycle · ERP systems · business process diagrams · flowcharts · data flow diagrams (DFDs)
03

Fraud & AIS Controls for Information Security

AIS threats · the fraud triangle · computer attacks & abuse · social engineering & malware · COSO framework · protect, detect & respond
04

Controls for Confidentiality, Privacy, Processing Integrity & Availability

Protecting confidentiality & privacy · encryption & digital signatures · processing integrity controls · availability & disaster recovery
05

Introduction to Systems Development & Systems Analysis

The systems development life cycle · planning systems development · feasibility analysis · behavioural aspects of change · systems analysis

08

Databases, DBMS & Relational Databases

Databases and database systems · the DBMS · logical vs physical views · the relational data model · normalisation basics
09

Database Design & REA Data Modelling

The database design process · entity-relationship (E-R) diagrams · the REA data model · developing & implementing an REA diagram
10

Data Analytics, ETL & Digital Business Reporting (XBRL)

Extract-Transform-Load (ETL) · data analytics & visualisation · interactive data · digital corporate reporting & XBRL
11

Data Analytics with Microsoft Power BI

Power BI Desktop & Service · building reports & dashboards · anomaly detection · key influencers · decomposition trees · smart narratives

You study three big areas: transaction processing and internal control (AIS fundamentals, ERP, flowcharts and DFDs, the fraud triangle, COSO, encryption and processing-integrity controls), the systems development process (the SDLC, feasibility analysis, design, conversion and development strategies such as prototyping and BPM), and database management and analytics (relational databases, REA data modelling, ETL and digital business reporting with XBRL, plus hands-on Microsoft Power BI).

The three assessments reward different skills: the two tests are fast, case-based recall and a Power BI practical, while the closed-book final is 50% of the mark and six compulsory case-study questions that ask you to unpack a scenario, state the theory, show its managerial relevance and illustrate it with an example.

High marks come from precise definitions and clean distinctions — authentication versus authorisation, virus versus worm, DFD versus flowchart, the three fraud-triangle legs, the four conversion strategies — applied to a business situation rather than just listed. Note that XBRL and digital reporting are examinable in the final but Power BI is not.

Feasibility analysis: payback, NPV and the feasibilities a positive NPV hides

Q [10 marks]. Torrens Freight is evaluating a new AIS. The outlay is $240,000 now and the system is expected to deliver net annual savings of $80,000 for 5 years. The firm's discount rate is 10% (the 5-year present-value-of-annuity factor is 3.791). Separately, warehouse staff must scan every pallet within a tight window each shift on top of their normal duties, and the scanners misread stock held in the freezer room. (a) Compute the payback period and the project NPV, and state whether the project is economically feasible. (b) Identify two other feasibility dimensions Torrens has overlooked and justify each.
  • +2Payback period = initial cost / annual net savings = 240,000 / 80,000 = 3.0 years — the outlay is recovered in three years.
  • +2Present value of the savings = 80,000 x 3.791 (the 5-year annuity factor) = $303,280.
  • +2NPV = PV of savings - initial cost = 303,280 - 240,000 = +$63,280. A positive NPV means the project is economically feasible.
  • +2Overlooked feasibility 1 = scheduling feasibility: the scan cannot reliably be completed in the tight per-shift window on top of normal duties, so the system may not operate within the time available.
  • +2Overlooked feasibility 2 = operational (and arguably technical) feasibility: the freezer-room misreads show the people and environment cannot use the technology as designed, so records will not be accurate — the people/process fit was never tested.
Payback = 3.0 years; NPV = +$63,280, so the project is economically feasible. But scheduling feasibility and operational feasibility were ignored — a positive NPV alone does not make a system viable.
Sia tip — Learn the five feasibilities with TELOS — Technical, Economic, Legal, Operational, Scheduling. The numeric economic part (payback = cost / annual savings; NPV = PV of benefits - cost; positive NPV = go) is easy marks; the case marks come from spotting the non-economic feasibilities the scenario quietly breaks.
Glossary

Key terms

Accounting information system (AIS)
The people, procedures, data, software, IT infrastructure and internal controls that collect, process and store transaction data and report information for decisions.
Give-get exchange
The reciprocal economic flow at the heart of every transaction cycle — the firm gives one resource to get another (e.g. revenue cycle = give goods, get cash).
Fraud triangle
The three conditions usually present in a fraud — pressure (motive), opportunity (weak controls that let it be committed and concealed) and rationalisation (self-justification).
COSO / COSO-ERM
Internal-control frameworks — COSO has 5 components; COSO-ERM extends it to 8, adding objective setting, event identification and risk response.
Authentication vs authorisation
Authentication verifies who you are (something you know, have or are); authorisation determines what you are allowed to do once identified, via an access-control matrix.
Digital signature
A document hash encrypted with the signer's private key; the receiver verifies it with the signer's public key, giving integrity and non-repudiation.
DFD vs flowchart
A data flow diagram is a logical model of data flow only (no decision diamonds); a flowchart is a physical model showing media, devices and manual/automated steps with decisions.
SDLC
The systems development life cycle — its five phases are systems analysis, conceptual design, physical design, implementation and conversion, and operations and maintenance.
Feasibility (TELOS)
The five feasibility dimensions assessed at go/no-go points — Technical, Economic, Legal, Operational and Scheduling.
Relational anomalies
The update, insert and delete problems caused by storing everything in one flat table; normalising into related tables with primary and foreign keys removes them.
REA data model
An AIS-specific data model that classifies every entity as a Resource, Event or Agent, with every give event paired to a get event (economic duality).
XBRL / iXBRL
The tagging standard for digital business reporting; each fact is tagged from a taxonomy into an instance document, and inline XBRL is both human- and machine-readable in one file.
FAQ

ACCTING 2503 FAQ

How is ACCTING 2503 assessed?

By three components: Test 1 (25%, 50 case-based questions in 60 minutes via the Respondus LockDown Browser), Test 2 (25%, a 30-question Power BI practical in 60 minutes) and a closed-book final exam (50%, 180 minutes, marked out of 100). You must also reach an aggregate of at least 50% across the three to pass.

Is there a final exam, and what is it like?

Yes. The final is closed-book, 180 minutes and worth 50%. It has six compulsory main questions, each with sub-parts, in an open-ended case-study/discussion style — you unpack the scenario, state the theory, show its managerial relevance and illustrate with an example. It covers the Week 1-10 topics plus digital reporting and XBRL, and excludes Power BI.

What is the hardest part of the course?

Most students find the volume of precise distinctions the hardest part — authentication vs authorisation, virus vs worm, DFD vs flowchart, incremental vs differential backup, the four conversion strategies and REA cardinalities. The exam plants these in a case and asks you to classify the facts, so memorising a label is not enough; you have to apply it.

Is Power BI on the final exam?

No. Power BI is assessed only in Test 2 as a practical. It is explicitly excluded from the final. The reverse is true for XBRL and digital corporate reporting, which are not in the tests but are examinable in the final.

How should I prepare?

Practise writing short structured answers to case prompts rather than re-reading notes: for each topic, keep a definition, a clean distinction and a one-line example ready. Build attack-vs-control and concept-vs-concept comparison lists, drill the few numeric bits (feasibility payback/NPV, PERT critical path, relational anomalies, ETL parsing), and rehearse the unpack-theory-relevance-example structure the final rewards.

Is this page official or affiliated with the University of Adelaide?

No. This is an independent AskSia study resource. It is not produced by, endorsed by or affiliated with the University of Adelaide. Always confirm assessment weights, dates and rules against your official course profile and learning management system.

Which textbook does the course use?

Romney, Steinbart, Summers and Wood, Accounting Information Systems, Global Edition, 16th Edition (Pearson, 2025). The final exam draws on the textbook topics covered in workshops plus digital reporting and XBRL.

Study strategy

How to study for the exam

Treat ACCTING 2503 as a course you pass with structured application, not memorisation. Read each week's material before the workshop, then turn every topic into a compact revision card carrying a precise definition, the one distinction the examiner loves to test, and a single business example — because the final's six case questions reward the unpack-theory-relevance-example pattern far more than a bare list.

Work backwards from how you are graded: drill the fast case-based recall for Test 1, do the actual clicks in Power BI Desktop and Service for Test 2 (which is excluded from the final), and make sure XBRL and digital reporting are solid because they are in the final even though Power BI is not.

Practise the handful of numeric problems — payback and NPV feasibility, PERT critical path, spotting relational anomalies, ETL parsing — until they are automatic, and mid-semester consolidate your comparison lists (authentication vs authorisation, virus vs worm, DFD vs flowchart, the conversion strategies, REA cardinalities).

In the STUVAC/revision week before the end-of-semester exam period, rehearse full timed case answers so structure and mark-allocation become second nature.
