Data flows can be described in terms of all of the following data structures EXCEPT:
- A.
A single attribute that is representative of a group of attributes
- B.
A sequence or group of data attributes that occur one after another
- C.
The selection of one or more attributes from a set of attributes
- D.
The repetition of one or more attributes
Correct Answer
A. A single attribute that is representative of a group of attributesExplanation
The given answer states that data flows can be described in terms of all of the following data structures except for a single attribute that is representative of a group of attributes. This means that data flows can be described as a sequence or group of data attributes that occur one after another, the selection of one or more attributes from a set of attributes, or the repetition of one or more attributes. However, a single attribute that represents a group of attributes is not a valid way to describe data flows.Rate this question:

All of the following is true about structured english except
- A.
Should use strong, imperative verbs
- B.
Pseudocode
- C.
A sequence of simple, declarative sentences
- D.
Uses only names that have been defined in the project dictionary
Correct Answer
B. PseudocodeExplanation
Structured English is a method of writing program specifications using a combination of natural language and programming constructs. It aims to make the specifications more readable and understandable for both technical and non-technical stakeholders. While structured English should use strong, imperative verbs, a sequence of simple, declarative sentences, and only names that have been defined in the project dictionary, it does not involve the use of pseudocode. Pseudocode is a more informal and less structured way of representing algorithms and is not typically used in structured English.Rate this question:

Correct Answer
E. System usersExplanation
The question asks for an exception among the given options, which are external agents, data stores, process concepts, data flows, and system users. Among these options, system users are not part of process models. Process models typically represent the flow of activities and interactions within a system, including external agents, data stores, process concepts, and data flows. System users, on the other hand, refer to the individuals or entities who interact with the system but are not represented within the process model itself.Rate this question:

All of the following are properties for the values for each attribute EXCEPT:
- A.
Data type
- B.
Domain
- C.
Null value
- D.
Default value
Correct Answer
C. Null valueExplanation
The question is asking about the properties for the values of each attribute, and it is asking for the property that is NOT included. The properties listed are data type, domain, null value, and default value. The correct answer is "null value" because it is the only property that is not typically associated with the values of an attribute. Data type refers to the type of data that can be stored in the attribute, domain refers to the set of possible values for the attribute, and default value refers to the value that is automatically assigned if no other value is specified.Rate this question:

Which type of normal form looks for transitive dependencies?
- A.
First normal form
- B.
Second normal form
- C.
Third normal form
- D.
Fourth normal form
- E.
Fifth normal form
Correct Answer
C. Third normal formExplanation
The third normal form looks for transitive dependencies. This means that in a table, if there is a dependency between two non-key attributes through another non-key attribute, it violates the third normal form. To achieve the third normal form, such transitive dependencies need to be removed by decomposing the table into multiple tables.Rate this question:

Which of the following best describes second normal form?
- A.
An entity whose attributes have no more than one value for a single instance of that entity
- B.
An entity whose non primary key attributes are dependent on the full primary key
- C.
An entity whose non primary key attributes are not dependent on any other non primary key attributes
- D.
None of the above
Correct Answer
B. An entity whose non primary key attributes are dependent on the full primary keyExplanation
Second normal form (2NF) is a database normalization rule that states that an entity should be in 1NF and all non-primary key attributes should be dependent on the full primary key. This means that each non-primary key attribute in the entity should be functionally dependent on the entire primary key, and not on any subset of the primary key. This helps to eliminate redundancy and ensures that data is stored efficiently and accurately in the database.Rate this question:

Correct Answer
A. A class of persons, places, objects, events, or concepts about which we need to capture and storeExplanation
An entity refers to a class of persons, places, objects, events, or concepts about which we need to capture and store data. This definition implies that entities are the fundamental building blocks of a data model, representing the various categories or types of information that we want to track and manage.

- D.
A single occurrence of an entity
Correct Answer
B. A property of an attribute that defines what values the attributes can legitimately take onExplanation
A domain is a property of an attribute that defines what values the attributes can legitimately take on. This means that a domain specifies the range of acceptable values for a particular attribute.

Which of the following is NOT considered a compound attribute
- A.
Name
- B.
Address
- C.
Gender
- D.
Phone number
Correct Answer
C. GenderExplanation
Gender is not considered a compound attribute because it represents a single characteristic or property of an entity. Compound attributes are composed of multiple sub-attributes that provide more detailed information. In this case, both name and address can have multiple sub-attributes such as street, city, and state, while phone number can have sub-attributes like country code and area code. However, gender does not have any sub-attributes and is therefore not considered a compound attribute.Rate this question:

Correct Answer
D. Temporal system data flow diagramExplanation
A temporal system data flow diagram is not a process model because it does not depict the flow of processes or activities within a system. Instead, it focuses on the temporal aspects of data flow, such as the timing and sequencing of data inputs and outputs. Process models, on the other hand, represent the flow of processes and activities within a system, showing how data moves through different stages or steps. The other options listed - context data flow diagram, functional decomposition diagram, external event diagram, and use case list - are all examples of process models commonly used in software engineering and system analysis.Rate this question:
