Project Description:

You have cataloged your vintage video games in an Access database. In this project, you add two tables to a database you have started? One to identify the game system that runs your game and the other to identify the category or genre of the game. Then you will join each table in a relationship so that you can query the database.

Start Access. Open the downloaded   Access file named Exp19_Access_Ch02_ML1_Games. Grader has automatically added   your last name to the beginning of the filename. Save the file to the   location where you are storing your files.

Open   the Games table and review the fields containing the game information. Close   the table.
 

  Create a new table in Design view. Add the field name SystemID and select AutoNumber as the Data Type. Add the caption System ID. Set the SystemID field as the primary   key for the table.

Add   a second field named SystemName   with the Short Text Data Type.   Change the SystemName field size property to 15.   Add the caption System Name.   Save the table as System.

Switch   to Datasheet view and enter the following system names, letting Access assign   the System ID:
 

XBOX 360
PS3
Wii
NES
PC Game
Nintendo 3DS
 

  Double-click the border to the   right of the System Name column to set the column width to Best Fit. Save and   close the table.

Create   a new table in Design view. Add the field name CategoryID   and select AutoNumber as the Data   Type. Add the caption Category ID.   Set the CategoryID field as the   Primary Key for the table.

Add   a second field named CategoryDescription   and accept Short Text as the Data   Type. Change the field size property to 25.   Add the caption Category Description.   Save the table as Category.

Switch   to Datasheet view, and enter the following Category Description, letting   Access assign the Category ID:
 

Action
Adventure
Arcade
Racing
Rhythm
Role-playing
Simulation
Sports
 

  Close the table.

Establish   relationships in the database by adding the Category, Games and System tables to the Relationships   window. Close the Show Table dialog box. Create a one-to-many relationship   between the SystemID field in the System table and the SystemID field in the   Games table, enforcing Referential Integrity. Select the option to cascade   update the related fields.

Create   a one-to-many relationship between the CategoryID field in the Category table   and the CategoryID field in the Games table, enforcing Referential Integrity.   Select the option to cascade update the related fields. Save and close the   Relationships window.

Create   a simple query using the Query Wizard. From the Games table, add the GameName and Rating fields (in that order). Save the query using the title Ratings. Switch to Design view. Sort the   Rating field in ascending order.

Click   the gray column selector at the   top of the Rating field, then click and drag the column to move it to the first position of the query design grid.   Add a Total row, click in the Totalrow   of the GameName column, click the arrow,   and then select Count. The records   will be grouped by rating, and the number of games will be counted for each   group. Run, save, and close the query.

Create   a new query in Design view. Add the Category,   Games, and System tables to the query design window. Add the following   fields to the query (in this order).
 

GameName

CategoryDescription
  Rating
  SystemName
  DateAcquired

Sort   the query in ascending order by GameName and run the query. Save the query as   Game List and close the query.

Copy   the Game List query in the   Navigation pane and paste it with the name PS3 Games.   Modify the query in Design view by using PS3   as the criteria for SystemName. Remove the sort by GameName and sort in   ascending order by CategoryDescription. Save and run the query. Close the query.

Create   a new query in Design view. Add the Category,   Games, and System tables to   the query design window. Add fields (in this order) to display the name of   the game, its rating, the category description of the game, and the system   name. You only want to display Wii games with a rating of Everyone or Teen.   Because the system name is the same for the games you plan to pack and share,   hide this value from the results. Save the query as Thanksgiving Games and run the query. Close the query.

1. For each of the following code segments, use OpenMP pragmas to make the loop parallel, or

explain why the code segment is not suitable for parallel execution.

a. for (i = 0; i < (int) sqrt(x); i++) {

a[i] = i + 12;

if (i < 10) b[i] = a[i];

}

b. flag = 0;

for (i = 0; (i < n) & (!flag); i++) {

a[i] = 2.8 * i;

if (a[i] < b[i]) flag = 1;

}

c. for (i = 0; i < n; i++) {

a[i] = fun(i);

}

d. for (i = 0; i < n; i++) {

a[i] = fun(i);

if (a[i] < b[i]) b[i] = a[i];

}

e. for (i = 0; i < n; i++) {

a[i] = fun(i);

if (a[i] < b[i]) break;

}

f. product = 0;

for (i = 0; i < n; i++) {

product += a[i] * b[i];

}

g. for (i = j; i < 3 * j; i++) {

a[i] = a[i] + a[i-j];

}

h. for (i = j; i < n; i++) {

a[i] = c * a[i-j];

}

2. Suppose a parallel program completes execution on 32 processors in 348 seconds, and it has

been found that this program spends 21 seconds in initialization and cleanup on one processor, and for

the remaining time all 32 processors are active. What is the scaled speedup of this parallel program?

3. Suppose a parallel program executing on 20 processors spends 98% of its time inside parallel

code. What is the scaled speedup of this parallel program?

4. The table below shows the speedups observed for six different parallel programs A, B, C, D,

E, F as the number of processors is increased from 1 through 8.

Using the Karp-Flatt metric as the basis, choose the statement that best describes the expected speedup

for each program with 16 processors.

I. The speedup achieved on 16 processors will probably be at least 40% higher than the speedup

achieved on eight processors.

II. The speedup achieved on 16 processors will probably be less than 40% higher than the speedup

achieved on eight processors, due to the increase in overhead as processors are added.

III. The speedup achieved on 16 processors will probably be less than 40% higher than the speedup

achieved on eight processors, due to the large serial component of the computation.

5. Let n ≥ f(p) denote the isoefficiency relation of a parallel system and let M(n) denote the

amount of memory required to store a problem of size n. Use the scalability function to rank the

parallel systems shown below from the most scalable to the least scalable:

a. f(p) = Cp, M(n) = n2.

b. f(p) = C√p, M(n) = n2.

c. f(p) = C√plog p, M(n) = n2.

d. f(p) = Cplog p, M(n) = n2.

e. f(p) = Cp, M(n) = n.

f. f(p) = Cp√p, M(n) = n.

g. f(p) = Cp2√p, M(n) = n.

6. Suppose a problem of size 100,000 can be solved in 15 hours on a computer today. Assuming

that the execution time is solely determined by the CPU speed, determine how large a problem can be

solved in 15 hours time by a computer that is 100 times as fast as today’s computer, if the algorithm

used to solve the problem has a time complexity given by (for a problem size of n):

a. Θ(n2)

b. Θ(nlog2n)

c. Θ(n3)

 Please read chapter 15 and review reputable articles/journals and describe what is Software Reuse? Briefly explain the benefits and problems with reuse.  

Modern cryptography uses public algorithms with secret material (keys). These public algorithms are arrived at through large scale “competitions” in which people compete to produce the most secure but efficient algorithm while also inspecting each other’s algorithms (see the NIST AES selection process). In this model of a publicly known encryption algorithm, the most protected element will be the key. Do you think it would enhance security to also have a secret algorithm agreed upon with your communication partners? Defend your answer.

 This course focuses on the skills & knowledge to guide an organization in its best use of technology to achieve its business goals and objectives. Although technical knowledge & skills are essential for technology professionals, this course focuses on the development of more general leadership skills. The ability to communicate with a broad set of stakeholders is essential & this course will offer exercises in skills such as negotiation, persuasion, agility, coaching & facilitation through case studies, role playing and simulation. Technology leaders must also understand the elements of developing & implementing an overall IT Strategy for the organization. This course will review the various levels of strategy & how strategy is implemented. 

Checkpoints
1) Include name, e-mail, and lab# as comments in the code and also include code to output this information to the output.2) Minimum of three (3) comments (including Pre/Post) in each function. Note that if the parameter is a reference to (i.e. address of) a value, then the Pre comment must so state.3) user defined constants for property tax rate, cost of utilities, and cost of insurance. use non-global memory constant for percent of down payment.4) use exactly one function separate from main for input.5) Call a calculation function from main which handles all calculations. This function needs to call a sub-function (another function) to calculate exactly the following and no more: amount of down payment, amount of the loan, amount of monthly mortgage payment.6) Use exactly one function separate from main for output.7) Output must be formatted exactly as shown on lab write-up with decimal points lined up. Output must be copied to a separate file.8) All functions (other than main() & your signature function) must use prototype style.9) use reference variables when necessary and ONLY WHEN NECESSARY.Test data (see bankrate.com or use Excel & pmt()to check your answers)

double calcBill(int nDrinks, int nPiz, double& sub, double& tax)
{
/* Pre: nDrinks – number of drinks
nPiz – number of pizzas
sub – reference to subtotal
tax – reference to tax
Post: total of the bill
Purpose: Calculate subtotal, tax, total
*/Also, please note that many of these “musts” are because I am endeavoring to make sure that you understand the underlying concepts and are not just blindly coding.
