“Business Rules in Data Modeling”  Please respond to the following:

 

Per the text, when databases are developed, they are modeled around business rules, so they accurately support a business function or operation.

Based on your experiences, identify one (1) example of a business function / operation. Explain the business function / operation in the context of business data models.

Identify the business rules associated with your selected business function / operation. Explain the manner in which such business rules would impact the design of a database.

 

Explain at least one (1) way in which the business function or operation would be affected if these business rules were not adhered to in the development of the database.

I am currently working on an employee registration system that is similar to KRONOS timekeeping system.
Use 3 to 4 diagrams to model a software system that you are familiar with. These diagrams should meet at least these criteria below, :

• There should be more than seven major components in this software system.
• There should at least be one dynamic view.

In the beginning weeks of our class, we have begun to think about some different ways in which identity is perceived, defined, and represented in the U.S., and when and how identity becomes political. Some key concepts we have engaged include: stereotypes, visibility of identity categories, “marked” and “unmarked” identities, oppression and power relationships between identity groups, self-identification and culture of identity, and problems of definition in recognizing identities.
In an essay of 3-5 pages (800-1250 words), respond to ONE of the following three questions, integrating no fewer than three (3) sources we have read or discussed in class. You may include outside examples from the media or popular culture in addition; if you do, please cite these using MLA citation format.
Be sure that you have a clearly stated thesis statement at the end of the introduction to your essay. One good way to do this is to underline that statement – if you have trouble finding it, you probably need to revise!
1. Class identity is often less visible in the United States than other aspects of identity. Explain why this is, and what kind of assumptions are in play in the representation of the underclass. You may wish to examine intersections of gender with class (working class women), or race with class (the association of poverty with people of color, for example). Where or how do we “see” some of these stereotypes being represented or refuted in the performance of Anna Deveare Smith, the writing of Barbara Ehrenreich, Dorothy Allison, or the coverage of Hurricane Katrina? [NOTE: don’t try to work with ALL of these texts – choose one or two quotes that support the argument you are making]

2. Race and ethnicity have functioned very differently as identity categories. Explain what the difference has been historically and how it is shaping the question “Who is Black?” today. What is the origin of the notion of “race” and what was its relationship to colonialism? What effects did the recognition of “races” have in terms of conferring status upon particular groups of people such as African Americans and Native Americans, and how has that translated into negative messages about identity?

3. Engage with the issue of “passing” and the specific problems encountered by people of mixed race (Smedley), or more specifically light-skinned African Americans as discussed by Davis. What is the “one-drop rule” and how have beliefs about black identity been shaped by it in the U.S.? Consider the recent controversy surrounding Rachel Dozeal and her self-identification as a black woman as an example through which to understand how racial identity functions in determining “who is black” in the U.S.

 

Some questions in Part A require that you access data from Statistics for People Who (Think They) Hate Statistics. This data is available on the student website under the Student Text Resources link.

1. Using the data in the file named Ch. 11 Data Set 2, test the research hypothesis at the .05 level of significance that boys raise their hands in class more often than girls. Do this practice problem by hand using a calculator. What is your conclusion regarding the research hypothesis? Remember to first decide whether this is a one- or two-tailed test.

2. Practice the following problems by hand just to see if you can get the numbers right. Using the following information, calculate the t test statistic.

a.
b.
c.
3. Using the results you got from Question 2 and a level of significance at .05, what are the two-tailed critical values associated with each? Would the null hypothesis be rejected?

4. Using the data in the file named Ch. 11 Data Set 3, test the null hypothesis that urban and rural residents both have the same attitude toward gun control. Use IBM® SPSS® software to complete the analysis for this problem.

9. The data set for this problem can be found through the Sage Materials in the Student Textbook Resource Access link, listed under Academic Resources. Using the data in Ch. 13 Data Set 2 and the IBM® SPSS® software, compute the F ratio for a comparison between the three levels representing the average amount of time that swimmers practice weekly (< 15, 15–25, and > 25 hours) with the outcome variable being their time for the 100-yard freestyle. Does practice time make a difference? Use the Options feature to obtain the means for the groups. Copy and paste the output from IBM® SPSS® into this worksheet.

10. When would you use a factorial ANOVA rather than a simple ANOVA to test the significance of the difference between the averages of two or more groups?

11. Create a drawing or plan for a 2 × 3 experimental design that would lend itself to a factorial ANOVA. Identify the independent and dependent variables.

Part B

The following questions in Part B require that you access data from Using SPSS for Windows and Macintosh. This data is available on the student website under the Student Text Resources link.

12. Review the one sample t-test instructional video before completing this problem. The data set for this problem can be found through the Pearson Materials in the Student Textbook Resource Access link, listed under Academic Resources. The data for this question is in the data file named Lesson 22 Exercise File 1. John is interested in determining if a new teaching method, the involvement technique, is effective in teaching algebra to first graders. John randomly samples six first graders from all first graders within the Lawrence City School System and individually teaches them algebra with the new method. Next, the pupils complete an eight-item algebra test. Each item describes a problem and presents four possible answers to the problem. The scores on each item are 1 or 0, where 1 indicates a correct response and 0 indicates a wrong response. The IBM® SPSS® data file contains six cases, each with eight item scores for the algebra test.

Conduct a one-sample t test on the total scores. On the output, identify the following:

a. Mean algebra score
b. T test value
c. P value

13. Review the one-way ANOVA instructional video before completing this problem. The data set for this problem can be found through the Pearson Materials in the Student Textbook Resource Access link, listed under Academic Resources. The data for this question is in the data file named Lesson 25 Exercise File 1. Marvin is interested in whether blonds, brunets, and redheads differ with respect to their extrovertedness. He randomly samples 18 men from his local college campus: six blonds, six brunets, and six redheads. He then administers a measure of social extroversion to each individual.

Conduct a one-way ANOVA to investigate the relationship between hair color and social extroversion. Conduct appropriate post hoc tests. On the output, identify the following:

a. F ratio for the group effect
b. Sums of squares for the hair color effect
c. Mean for redheads
d. P value for the hair color effect
