The term usability encompasses TWO related concepts. What are they?
Ease of use and ease of learn
When implementing the 'minimize user effort' factor, most interface designers follow the
______________
Three-click rule
Typically, the first step in the user interface design process is
Understand the user
Map the following principles for user interface design with the correct example for each principle.
Layout
Content awareness
Aesthetics
Consistency
Layout - a top area is used for commands and navigation
Content Awareness - use breadcrumbs to list pages in a hierarchical order
Aesthetics - never use all capital letters, except possibly for titles
Consistency - use the same icon and/or command to perform a search
Assume you are developing an interface design prototype for your system. If your goal is to convey
the basic content and behavior of the screen or the screen's functionality, and not how it looks, which
interface design prototype method will you use?
Wireframe
A design prototyping method that allows an analyst to envision the use of the screens (both the
screen's functionality (including how the screen will look like) and the flow form one screen to
another) to accomplish an overall task is called _____________
Wireflow diagram
One of the basic principles of the navigation design is
Simplify recovery from mistakes
One method you can use to organize your interface is ____________
Site map
An interface evaluation technique that allows users to actually work with the prototype in one-on-one
sessions with members of the project team and convey their opinions (what they like/dislike) about
the interface is called ___________
Interactive evaluation
Which of the following is NOT a general test stage?
Module testing
(system testing, unit testing, integration testing are)
, An n-tiered architecture is distinguished by:
The number of specialized server computers
Valery is testing a new payroll system at her company. Her goal is to test whether the original
business requirements are met by the new system. This test is also to ensure that changes made as
the result of integration testing did not create new errors. What type of testing does she do?
Requirement testing
A type of unit testing that looks inside the program to test its major element is called _______
White-box testing
The two fundamental documentation types are:
System documentation and user documentation
Which one of the following options is an example of access control requirement?
Customer service reps can modify customer files but not delete them
What is a server-based architecture?
When the server is performing all four application functions and the clients only capture keystrokes
The primary hardware components of a system consist of:
Client computers, servers, and network
What is the objective of architecture design?
To determine what parts of the application software will be assigned to what hardware
What is a common process analysts use to validate data models?
Normalization
When normalizing data models, if you take attributes that have multiple values for a single instance of
an entity and create separate entities for those attributes, you are checking
1st normal form
According to the video lectures on ERD normalization from DFD Level-0, how do you identify the
entities from a Data flow diagram?
From datastores and external entities of an DFD
According to the video lectures on normalization, there are THREE potential anomalies that can be
associated with the 1st Normal Form. What are these anomalies?
Insert, deletion, and update anomalies
Under the ORDERED ITEM entity, the Item_Name attribute only depends on Item_Number, but not
Order_Number. In an ERD, this kind of dependency is called
