AIS Chapter 2: Intro to
Transaction Processing fully
solved & updated
Documentation - answer Documentation in a digital environment is
necessary for many reasons.
•Common documentation techniques:
-Entity Relationship Diagram
-Data Flow Diagrams
-System Flowcharts
-Program Flowcharts
*only concerned with flowcharts
System Flowchart - answer •Graphical representation of the
physical relationships among key elements of the system (computer
program, files and outputs)
•Represents the system, whether manual, computer-based or some
combination
•Clearly depict the separation of functions in a system
•Does not include all operational detail
, (18 shapes)
Rules & Conventions for flowcharts - answer •Label the flowchart to
clearly identify the system (or portion of system) being represented
•Columns used for separation to depict areas of activity or
responsibility
•Use correct symbols
•Label all symbols
•Ensure lines have arrows going in the appropriate direction
•Attach text descriptions if highly complex.
Program flowchart - answer diagram providing a detailed
description of the sequential and logical operations of the program
(it is the logic of a program that is shown in a system flowchart)
•Separate symbol represents each step of the program's logic
•Each symbol represents one + lines of code
•Connector lines establish the logical order of execution
Financial Transaction; 3 transaction cycles - answer •similar types of
transactions are grouped together into three transaction cycles:
-the expenditure cycle
