How does SQL Work?
|
SQL operates on complete tables, as opposed to the individual rows in the tables.
Thus, a query written in SQL is applied to all of the rows in a table all at once, which is different than a lot of programming languages that manipulate data row by row.When queries must include information from more than one table, the tables first are joined together based on their primary key and foreign key relationships and treated as if they were one large table. |
|
|
What are some parts of a DB/Table?

A table with a primary key, foreign key. Columns, rows, and values.

|
|
What are the differences between RDBMS, ORDBMS, & OODBMS, What are their basic strengths, 1NF, 2NF, 3NF, and how to create them.
|
An RDBMS supports referential integrity, an ORDBMS does as well, except it's object oriented. Then OODBMS is an Object oriented database management system. With OODBMS collections of objects are associated with an extent.

Designs for different users should be...
|
while experts refer the status bar when they need information.Most
systems should be designed to support frequent users, except for systems designed to be used infrequently or when many new users or occasional users are expected (e.g., the Web). Likewise, systems that contain functionality that is used only occasionally must contain a highly intuitive interface, or an interface that contains clear explicit guidance regarding its use. |
|
|
Best types of fonts, colors, etc for an HCI design
|
All interfaces should be aesthetically
pleasing (not works of art) and need to include significant white space, use colors carefully, and be consistent with fonts. Most interfaces should be designed to support both novice/first time users, as well as experienced users. Consistency in design (both within the system and across other systems used by the users) is important for the navigation controls, terminology, and the layout of forms and reports. Finally, all interfaces should attempt to minimize user effort, for example, by requiring no more than three clicks from the main menu to perform an action. |

2nd Normal Form

Transitive Dependencies Removed
|

|
3rd Normal
|
No transitive dependencies, no partial dependencies.
|
|
|
Use of white space?
|
Interfaces should be functional and inviting to users through careful use of
white space, colors, and fonts. There is often a tradeoff between including enough white space to make the interface look pleasing without losing so much space that important information does not fit on the screen. |
|
|
What is an interface metaphor?
|
An interface metaphor is a concept
from the real world that is used as a model for the computer system. The metaphor helps the user understand the system and enables the user to predict what features the interface might provide, even without actually using the system. |
|
|
What is an interface object?
|
Interface objects are the fundamental building blocks of the system, such as the classes.
|
|
|
What is an interface action?
|
Interface Actions The template also specifies the navigation and command language
style (e.g., menus), and grammar (e.g., object-action order; see the navigation design section later in this chapter). It gives names to the most commonly used interface actions in the navigation design (e.g., “buy” versus “purchase” or “modify” versus “change”). |
|
|
What is Heuristic Evaluation
|
Heuristic evaluation examines the interface by comparing it to a
set of heuristics or principles for interface design. |
|
|
What is a walk through evaluation?
|
Walkthrough Evaluation An interface design is a meeting conducted with the users who
will ultimately have to operate the system. The project team presents the prototype to the users and walks them through the various parts of the interface. The project team shows the storyboard or actually demonstrates the HTML or language prototype and explains how the interface will be used. The users identify improvements to each of the interfaces that are presented. |

Have an undo option, or a way to make mistakes easy to override.
use consistent grammar order. |
