Deck 9: Process Modeling

Question 1

A model is a representation of reality

Answer 1

True

Logical models show what a system is or does. They are implementation independent.

Answer 2

True

Question 3

Logical models show how a system is implemented.

Answer 3

False

Question 4

Physical models show not only what a system is or does, but also how the system is physically and technically implemented. They are implementation independent because they specify the technology.

Question 5

Logical models show not only what a system is or does, but also how the system is implemented.

Question 6

Process modeling is a technique for organizing and documenting the structure and flow of data through a system's processes and /or the logic, policies and procedures to be implemented by a system's processes.

Question 7

A data flow diagram (DFD) is a tool that depicts the flow of data through a system and the work or processing performed by that system.

Question 8

An entity relationship diagram (ERD) is a tool that depicts the flow of data through a system and the work or processing performed by that system.

Question 9

A data flow diagram is a process model.

Question 10

Another name for the data flow diagram is an entity relationship diagram.

Question 11

In a data flow diagram, rounded rectangles are used to represent processes.

Question 12

In a data flow diagram, squares are used to represent external agents - the boundary of the system.

Question 13

In a data flow diagram, rounded rectangles are used to represent external agents - the boundary of the system.

Question 14

Data flow diagrams have found new use in business process redesign.

Question 15

A process is work performed on, or in response to, incoming data flows or conditions. A synonym is transform.

Question 16

Data describe work to be performed on, or in response to, incoming process flows or conditions.

Question 17

In data flow diagrams, open-ended boxes represent data stores.

Question 18

In data flow diagrams, open-ended boxes represent external agents.

Question 19

In data flow diagrams, arrows represent data flows.

Question 20

A system is a process.

Question 21

If data modeling is done before process modeling, the agents on the DFD can be pulled from the entity relationship diagram.

Question 22

The use of logical models reduces the risk of missing business requirements.

Question 23

Data Flow Diagrams are a kind of flowchart.

Question 24

A complex system is usually easy to understand when viewed as a whole.

Question 25

Decomposition is the act of breaking a system into component subsystems, processes and subprocesses.

Question 26

During decomposition, each level of abstraction reveals more or less detail as desired, about the overall system or a subset of that system

Question 27

In systems analysis, decomposition allows you to partition a system into logical subsystems of processes for improved communication, analysis and design.

Question 28

A decomposition diagram is also called a hierarchy chart.

Question 29

A data flow diagram shows the top down functional decomposition and structure of a system.

Question 30

A decomposition diagram is a tool that depicts the flow of data through a system and the work or processing performed by that system.

Question 31

A hierarchy chart is another name for a decomposition diagram.

Question 32

A decomposition diagram is essentially a planning tool for more detailed process models, namely, data flow diagrams.

Question 33

Logical processes are work or actions that must be performed no matter how you implement the systems.

Question 34

Physical processes are work or actions that must be performed no matter how you implement the systems.

Question 35

Each logical process must be implemented in software.

Question 36

A function is a set of related and ongoing activities of the business.

Question 37

An event is a logical unit of work that must be completed as a whole.

Question 38

An event is a logical unit of work that can be completed in parts over time.

Question 39

An event is triggered by a discrete input and is completed when the process has responded with the appropriate outputs.

Question 40

An event is triggered by a discrete output that is completed when the process has responded with the appropriate inputs.

Question 41

Events are sometimes called transactions.

Question 42

A function is a unit of work that must be completed as a unit or whole.

Question 43

Elementary processes are discrete, detailed activities or tasks required to complete the response to an event.

Question 44

Elementary processes are the overall activities to be accomplished by a system.

Question 45

Elementary processes are at the highest level of detail when depicted in a process model.

Question 46

Elementary processes are the lowest level of detail when depicted in a process model.

Question 47

Primitive processes are the lowest level of detail when depicted in a process model.

Question 48

A black hole is a process that has inputs but no outputs.

Question 49

A black hole is an acceptable elementary process.

Question 50

Gray holes can be caused by a misnamed process.

Question 51

A gray hole is a process where the inputs are insufficient to produce the desired outputs.

Question 52

A data store represents data in motion.

Question 53

A logical process can perform computations.

Question 54

A logical process can make decisions.

Question 55

A logical process can trigger other processes.

Question 56

A logical process can use stored data to create, read, update or delete a record.

Question 57

Structured English is a language and syntax, based on the relative strengths of structured programming and natural English, for specifying the underlying logic of elementary processes on process models such as data flow diagrams.

Question 58

An iteration structure specifies that a set of steps should be repeated based on some stated condition.

Question 59

A repetition structure specifies that a set of steps should be repeated based on some stated condition.

Question 60

A conditional structure specifies that a set of steps should be repeated based on some stated condition.

Question 61

A conditional structure specifies that a process must perform different steps under well-specified conditions.

Question 62

A function is a set of related and ongoing activities of the business.

Question 63

A restriction of Structured English is that only strong, imperative verbs may be used.

Question 64

A restriction of Structured English is that only names that have been defined in the project dictionary may be used.

Question 65

Structured English allows the analyst to define new terms as the process is being defined.

Question 66

A restriction of Structured English is that formulas should be stated clearly using appropriate mathematical notations.

Question 67

Undefined adjectives and adverbs are not permitted in Structured English unless they have been clearly defined in the project dictionary.

Question 68

Blocking and indentation should be used in Structured English to set off the beginning and ending of constructs to enhance readability.

Question 69

Spacing, blocking and indentation are not important in Structured English since it is not a formal programming language.

Question 70

In Structured English, when in doubt, user readability should take priority over programmer preferences.

Question 71

Structured English should be precise enough to clearly specify the required business procedure to a programmer or user. But it should not be so inflexible that you spend hours arguing over syntax.

Question 72

Structured English is very precise and requires a strict adherence to syntax rules so that it can be translated for specifications to programming code directly.

Question 73

Simple condition steps can be translated into programming language as a For loop.

Question 74

A policy is a set of rules that governs some process in the business.

Question 75

Both decision tables and Structured English can describe a single elementary process.

Question 76

A decision table is a tabular form of presentation that specifies a set of conditions and their corresponding actions.

Question 77

A decision table is expressed in Structured English to facilitate the presentation of policies and processes using a single technique.

Question 78

Decision tables are useful for specifying complex policies and decision-making rules.

Question 79

The three components of a decision table are: condition stubs, action stubs and rules.

Question 80

The three components of a decision table are: entities, relationships and attributes.
