AIS 242 (2) Flashcards
This is an economic event that affects the assets and equities of the firm, is reflected in its accounts, and is measured in monetary terms
Financial Transaction
Similar types of transactions are grouped together into three transaction cycles which are?
the expenditure cycle,
the conversion cycle, and
the revenue cycle.
Each cycle has 2 subsystems
This manual accounting record is used to capture and formalize transaction data needed for transaction processing
Source Document
This manual accounting record is the result of transaction processing
Product Documents
This manual accounting record is a product document of one system that becomes a source document for another system
Turnaround Documents
This manual accounting record is a record of chronological entry
Journal
This record contains specific classes of transactions that occur in high frequency
Special Journal
This record contains nonrecurring, infrequent, and dissimilar transactions
General Journal
This record shows activity by detail for each account type
Subsidiary Ledger
This manual accounting record is the book of financial accounts
Ledger
This record shows activity for each account listed on the chart of accounts
General Ledger
This computer file is a temporary file containing transactions since the last update
Transaction File
This computer file contains relatively constant information used in processing (e.g., tax tables, customer addresses)
Reference File
This computer file generally contains account data
Master File
This computer file contains past transactions for reference purposes
Archive File
Five common documentation techniques
Entity Relationship Diagram
Data Flow Diagrams
Document Flowcharts
System Flowcharts
Program Flowcharts
This is a documentation technique to represent the relationship between entities in a system.
Entity Relationship Diagram
The REA model version of ER is widely used in AIS.
This represents the numerical mapping between entities
Cardinalities
one-to-one
one-to-many
many-to-many
The REA model version of ER is widely used in AIS. REA uses 3 types of entities which are?
resources (cash, raw materials)
events (release of raw materials into the production process)
agents (inventory control clerk, vendor, production worker)
This documentation technique uses symbols to represent the processes, data sources, data flows, and entities in a system
Data Flow Diagrams (DFD)
represent the logical elements of the system
does not represent the physical system
This documentation technique illustrates the relationship among processes and the documents that flow between them. It contain more details than data flow diagrams and clearly depicts the separation of functions in a system
Documents Flowcharts
What do the following symbols mean in a document flowchart?
Oval
Rectangle with a tail on the left
Upside down Trapezoid
Triangle
Parallelogram
Long rectangle with a tail on the right
o
Upside down pentagon
-[
->
In the same order they mean
Oval = Terminal showing source or destination of documents
Rectangle with a tail on the left = Source document or report
Upside down Trapezoid = Manual Operation
Triangle = File for storing source documents or reports
Parallelogram = Accounting records
Long rectangle with a tail on the right = Calculated batch total
o = On page connector
Upside down pentagon = Off page connector
-[ = description of process or comments
-> = Document Flowline
This documentation technique is used to represent the relationship between the key elements–input sources, programs, and output products–of computer systems. It depicts the type of media being used (paper, magnetic tape, magnetic disks, and terminals), and in practice, there isn’t much difference between this and document flowcharts
System Flowcharts
What do the following symbols mean in a system flowchart?
Rectangle with a tail on the left
Rectangle
Cylinder
Tape
Irregular Trapezoid
—>
Line that looks like a Z
Sideways Pentagon ([]>)
In the same order they mean
Rectangle with a tail on the left = Hard Copy
Rectangle = Computer Process
Cylinder = Direct access storage device
Tape = Magnetic Tape
Irregular Trapezoid = Terminal input/output device
—> = Process Flow
Line that looks like a Z = Real time connection
Sideways Pentagon ([]>) = Video Display Device
This documentation technique is used to illustrate the logic used in programs
Program Flowcharts
What do the following symbols mean in a program flowchart?
Rectangle
Diamond
Oval
Parallelogram
——>
In the same order they mean
Rectangle = Logical Process
Diamond = Decision
Oval = Terminal Start or end operation
Parallelogram = Input/Output Operation
——> = Flow of logical process
What are the 2 broad classes of computer accounting systems?
Batch Systems
Real Time Systems
This processes at the moment the economic event occurs and has no time lag between the economic event and the processing
Real-Time Systems
generally require greater resources than batch processing since they require dedicated processing capacity; however, these cost differentials are decreasing
oftentimes have longer systems development time
This is a group of similar transactions that are accumulated over time and then processed together.
A _______ exists between the event and the processing.
Batch, Time Lag
(The transactions must be independent of one another during the time period over which the transactions are accumulated in order for batch processing to be appropriate.)
What are the steps in Batch Processing?
- Keystroke
- Edit Run
- Sort Run
- Update Run
- Backup Procedure
