Quiz 9 - Chapter 9

Which of the following is NOT one of the main problems that can occur in developing decision tables? - incompleteness - impossible situations - contradictions - repetition

Repetition

When structured decisions are not complex, an appropriate technique for analyzing the decision process is the use of [blank]. - CASE tools - structured English - decision trees - decision diagrams

Structured english

Which of the following is NOT a problem when creating decision tables? - impossible situations - too many conditions - redundancy - contradictions

Too many conditions

Which of the following is NOT a business rule? - business conditions and actions - user ethics - logical inferences - processing sequences

User ethics

A goal of producing process specifications is to: - reduce process interactions - build technical specifications for specific computer language - validate the system design, including data flow diagrams and the data dictionary - design computer input and output processes

Validate he system design, including data flow diagrams and the data dictionary

Which of the following is NOT a goal of producing process specifications? - to reduce the ambiguity of the process - to reduce the time it takes for a process to run - to obtain a precise description of what is accomplished - to validate the system design

To reduce the time it takes for a process to run

Process logic may be represented as: - structured English - a decision table - a decision tree - a formula - all of the above

All of the above

When drawing the tree, systems analyst do NOT have to identify: - all outcomes - all actions - the order - all conditions

All outcomes

When selection is indicated for elements in the data dictionary: - a simple sequence of structured English statements is all that is necessary - an IF...THEN...ELSE structure must be present in the structured English statements - DO WHILE, DO UNTIL, or PERFORM UNTIL structured English statements must be included - a decision tree must be used to depict the logic

An IF...THEN...ELSE structure must be present in the structured English statements

In order to use structured English, which convention is NOT advisable? - express all logic in terms of sequential structures, decision structures, case structures, or iterations - blank a a line and indent blocks of statements to show their hierarchy - use and capitalize accepted keywords such as IF, THEN - be careful when using "and" and "or"

Blank a line and indent blocks of statements to show their hierarchy

Process descriptions may exist on a form or within a [blank] repository. - data - data dictionary - CASE tool - CASE diagram

CASE tool

Which of the following is NOT one of the three basic constructs used to code computer programs? - sequence - selection - iteration - computation

Computation

When creating process specifications, what needs to be done for manual tasks? - create well-defined procedures or employees performing the tasks - replace them with automated processes - outline the decisions using a decision tree - nothing, they are not part of processing specifications

Create well-defined procedures for employees performing the tasks

When iteration is indicated for an element or a group of elements in the data dictionary: - a simple sequence of structured English statements is all that is necessary - an IF...THEN...ELSE structure must be present in the structured English statements - DO WHILE, DO UNTIL, or PERFORM UNTIL structured English statements must be included - a decision tree must be used to depict the logic

DO WHILE, DO UNTIL, or PERFORM UNTIL structured English statements must be included

What is a way to examine, describe, and document structured decisions? - decision table - data flow - data dictionary - database

Decision table

In order to build decision trees, what does the analyst NOT need to do? - eliminate any impossible situations - simplify the table as much as possible - determine the minimum size of the table - eliminate inconsistencies

Determine the minimum size of the table

Which of the following is NOT an example of a keyword for structured English? - IF - DO - PERFORM - IS LIKE

IS LIKE

Running a section of code over and over again until some condition is met is an example of a: - loop - IF...THEN - DO...WHILE - decision table

Loop

Process specifications are sometimes called [blank], because they are a small portion o the total project specifications. - designs - data flows - information nodes - minispecs

Minispecs

Which is NOT one of three main advantages of a decision tree over a decision table? - more correct as a communication tool - sequential structure of decision tree branches - conditions and actions of decision trees are found on some branches - more readily understood

More correct as a communication tool

Structured English can be more complex if blocks of (instructions) are [blank] within each other to show hierarchy. - nested - grouped - selected - placed

Nested

In order to determine the human information requirements using a decision analysis strategy, what must the systems analyst determine? - necessary data - objectives - information - data structure

Objectives

Unlike the decision tree used in management science, what doesn't the analyst tree contain? - decisions - conditions - outcomes - actions

Outcomes

One of the goals of producing [blank] is to validate the system design, including the data flow diagram and the data dictionary. - process specifications - process diagrams - process databases - production specifications

Process specifications

[Blank] are created for primitive processes on a data flow diagram. - process specifications - process diagrams - process databases - production specifications

Process specifications

Primitive process specifications are NOT produced for: - processes that use decision trees - processes for which pre-written code already exists - processes that involve complex editing - all of the above

Processes for which pre-written code already exists

Which of the following is NOT a business rule? p logical inferences - mathematical and functional derivations - programming language IF statements - definitions of business terms

Programming language IF statements

In a decision table, contradictions occur when: - an important condition is omitted - when the situation cannot occur because there are two or more conditions that cannot occur at the same time - identical sets of alternatives require the same action - rules suggest different actions but satisfy the same conditions

Rules suggest different actions but satisfy the same conditions

Which is structured English NOT based on? - instructions organized into nested and grouped procedures - simple English statements - unstructured logic - add, multiply, move, and so on

Unstructured logic

Which is the correct choice? - Use structured English when not every condition is relevant to every action - Use decision tables when communication to end users is important - Use decision trees when the sequence of conditions and actions is critical - Use decision tables when there are many repetitious actions

Use decision trees when sequence of conditions and actions is critical
