"Maintaining Data Integrity" Please respond to the following:

Describe the importance of maintaining integrity rules throughout the database structure. Create at least three examples of common relationships that are used within a relational database system. Justify your response.
Many times, database designs do not include the proper use of indexes. Provide a specific example on how an index could be used in order to enhance user search experience. List specific fields that you would index. Analyze what would occur if the proper index is not included, with respect to your example.

CIS 515 WEEK 1 ASSIGNMENT 1

Assignment 1: Accessing Oracle
Due Week 1 and worth 10 points

Your instructor will provide you with login credentials to a Strayer University maintained Oracle server. Once you have received these credentials, you will need to log in to the Oracle server and document your login to verify your credentials work and you can complete the activities later in the course. This assignment requires the use of a snipping tool or print screen option on a keyboard to document the completion of this assignment.

Write a one to two (1-2) page paper in which you:

Use the print screen option on a keyboard or a snipping tool to capture screen shots of your telnet session into the Oracle server. Note:The graphically depicted solution is included in the required page length.
Briefly describe the steps used to log into the Strayer Oracle server.

"Electronic Ballots" Please respond to the following:

One criticism of electronic ballots for elections is that while intuitive for younger voters who are familiar with using a mouse to point and click, elderly voters and motor-impaired users will have difficulty controlling a mouse. Discuss how you would correct this issue so that every demographic would have an equal opportunity to vote. Support your answer.
Imagine you have just finished interviewing a recent college graduate for a design position within your company. At the end of the interview, the college graduate remarks that design would be much easier if people conformed to the design, rather than the design having to be accessible to diverse populations. Respond to this comment, addressing the legal, societal, and ethical issues that designers face in regard to human-computer interaction.

CIS 524 Week 3 Discussion 2

"Interface Design Models" Please respond to the following:

Evaluate interface design models and describe design issues across human-computer interaction environments associated with these models. Support your response.
Building an interface can be broken down into the phases of design and development. Analyze the activities that take place in both phases, and explain why certain activities should be included in design but not in development.

CIS 524 Week 2 Discussion 1
"Interface Design Guidelines" Please respond to the following:

Imagine you are leading a team of designers for a new software product. During the kickoff meeting, the team starts to discuss design guidelines. About half of the team complains that guidelines can be too specific, incomplete, hard to apply, and sometimes wrong. The other half feels that building on experience from design leaders contributes to steady improvements. Take a stance on this debate and support your position. Then discuss how you would solve this conflict to get your meeting back on track.
Of the eight principles of design, called “Golden Rules” (strive for consistency, cater to universal usability, offer informative feedback, design dialogues to yield closure, prevent errors, permit easy reversal of actions, support internal locus of control, and reduce short-term memory load) choose the one that is most important and create an argument supporting your choice. Use specific examples to support your argument.

"HCI Theories" Please respond to the following:

Imagine you are the manager of a medium-sized IT department. While walking through the hall one day, you overhear a senior-level software developer telling a newly hired developer to focus on improving his coding skills rather than learning about theories related to human-computer interaction. Take a position on whether you agree or disagree with the senior software developer. Support your decision.
From the e-Activity, discuss the idea that all applications have to be visually consistent. Argue whether you agree or disagree with the idea and why.

Creating an Interface" Please respond to the following:

Imagine you are managing a design project that will create an interface for automobile mechanics. The interface would be used by the mechanics to look up various fixes and parts for any number of makes or models of automobiles that may come through their garage. Decide what usability measures would be most motivating when designing this interface and describe the unique challenges you would have to plan for when designing an interface for an automotive repair shop. Use supporting evidence to support your response.
Physical, cognitive, perceptual, personality, and cultural differences introduce challenges when designing universally usable products. Choose one area from the list above and describe why it is the biggest challenge to overcome when creating universally usable designs. Support your response.

CIS 524 Week 1 Discussion 2
"Goal Setting" Please respond to the following:

Early computers were only usable by experts with strong technical knowledge. Examine how interactive systems have changed throughout the years to accommodate average users and describe two advantages and two disadvantages associated with these changes.
From the e-Activity, examine the two articles you selected on universal usability and discuss one topic of interest that was addressed.
