Systems Design Chapter 10 Flashcards
Automation System Boundary
partitions the data flow diagram processes into manual processes and those that are to be included in the computer system
System Flow Chart
Representation of various computer programs, files, databases, and associated manual procedures that make up a complete system.
Structure Chart
hierarchical diagram showing the relationships between the modules of a computer program
Data Couples
the individual data items that are passed between modules in a program call.
Transaction Analysis
the development of a structure chart based on a DFD that describes the processing for several types of transactions
Transform Analysis
the development of a structure chart based on a DFD that describes the input-process-output data flow
Module coupling
the manner in which modules relate to each other; the preferred method is data coupling
Automation System Boundary
partitions the data flow diagram processes into manual processes and those that are to be included in the computer system
Module Cohesion
a measure of the internal strength of a module
Flowcharting
is a visual method that uses boxes and lines to describe the flow of logic in a program.
Structured English
describes the structure of the program in regular english
pseudocode
closer to programming language
three layer design
