What are the advantages of using a database management system (DBMS) over using file-based data storage?
Answer:
Advantage of DBMS over file system
No redundant data: Redundancy removed by data normalization. No data duplication saves storage and improves access time.
Data Consistency and Integrity: As we discussed earlier the root cause of data inconsistency is data redundancy, since data normalization takes care of the data redundancy, data inconsistency also been taken care of as part of it
Data Security: It is easier to apply access constraints in database systems so that only authorized user is able to access the data. Each user has a different set of access thus data is secured from the issues such as identity theft, data leaks and misuse of data.
Privacy: Limited access means privacy of data.
Easy access to data – Database systems manages data in such a way so that the data is easily accessible with fast response times.
Easy recovery: Since database systems keeps the backup of data, it is easier to do a full recovery of data in case of a failure.
Flexible: Database systems are more flexible than file processing systems

Ramjac Company wants to set up k independent file servers, each capable of running the company's intranet. Each server has average "uptime" of 98 percent. What must k be to achieve 99.999 percent probability that the intranet will be "up"?
Answer:
k = 3
Explanation:
K independent file servers
Average "uptime" of each server = 98%
To achieve 99.99% probability by the intranet
given that each server has an uptime = 98%
For the intranet to achieve 99.99% probability we have to choose more than 2 servers ( i.e. 3 servers ) incase any of the server goes down.
As each server posses an uptime of 98% it is almost impossible for all 3 servers to go down at the same time hence value of K = 3
It should be noted that the value of k to achieve 99.99 percent probability will be 3.
How to solve the probabilityFrom the information given, k is simply the independent file servers.
Also, the average uptime of each server is given as 98%. For the intranet to achieve 99.99% probability, it should be noted that more than 2 servers will be chosen.
In this case, it'll be impossible for the three servers to go down.

.13 LAB: Library book sorting Two sorted lists have been created, one implemented using a linked list (LinkedListLibrary linkedListLibrary) and the other implemented using the built-in Vector class (VectorLibrary vectorLibrary). Each list contains 100 books (title, ISBN number, author), sorted in ascending order by ISBN number. Complete main() by inserting a new book into each list using the respective LinkedListLibrary and VectorLibrary InsertSorted() methods and outputting the number of operations the computer must perform to insert the new book. Each InsertSorted() returns the number of operations the computer performs. Ex: If the input is:
Answer:
linkedListOperations = linkedListLibrary.InsertSorted(currNode, linkedListOperations); // this is right
linkedListLibrary.InsertSorted(currNode, linkedListOperations); // half right, it count how much operation but it doesn't store it anywhere in main.
vectorOperations = vectorLibrary.InsertSorted(tempBook, vectorOperations); // this is right
vectorLibrary.InsertSorted(tempBook, vectorOperations); // half right, it count how much operation but it doesn't store it anywhere in main.
cout << "Number of linked list operations: " << linkedListOperations << endl;
cout << "Number of vector operations: " << vectorOperations << endl;
Explanation:
The first, you are calling InsertSorted with linkedListLibrary and than you can store the number of operation inside the "linkedListOperations" variable. Then you do the same with vectorLibrary.

Presentation of the data abstracted from the database must take one of two forms: graphs and tabular forms. True False
Answer:
False.
Explanation:
There is also a third way of presenting data. Data can be presented in textual form, using paragraph structures. The other two are using graphs and tabular forms. Presenting data in a graph or pie chart gives a pictorial representation of the data, making the numbers easier to visualize and understand. Using tables also makes data presentation to be easily communicated. Text remains the method for explaining findings, outlining trends, and providing context, a table represents both quantitative and qualitative information, while a graph displays data for comparison.
IN C++
A. Create an abstract base class called Currency with two integer attributes, both of which are non-public. The int attributes will represent whole part (or currency note value) and fractional part (or currency coin value) such that 100 fractional parts equals 1 whole part.
B. Create one derived class - Money - with two additional non-public string attributes which will contain the name of the currency note (Dollar) and currency coin (Cent) respectively. DO NOT add these attributes to the base Currency class.
C. In your base Currency class, add public class (C++ students are allowed to use friend methods as long as a corresponding class method is defined as well) methods for the following, where appropriate:
Default Construction (i.e. no parameters passed)
Construction based on parameters for all attributes - create logical objects only, i.e. no negative value objects allowed
Copy Constructor and/or Assignment, as applicable to your programming language of choice
Destructor, as applicable to your programming language of choice
Setters and Getters for all attributes
Adding two objects of the same currency
Subtracting one object from another object of the same currency - the result should be logical, i.e. negative results are not allowed
Comparing two objects of the same currency for equality/inequality
Comparing two objects of the same currency to identify which object is larger or smaller
Print method to print details of a currency object
All of the above should be instance methods and not static.
The add and subtract as specified should manipulate the object on which they are invoked. It is allowed to have overloaded methods that create ane return new objects.
D. In your derived Money class, add new methods or override inherited methods as necessary, taking care that code should not be duplicated or duplication minimized. Think modular and reusable code.
E. Remember -
Do not define methods that take any decimal values as input in either the base or derived classes.
Only the print method(s) in the classes should print anything to console.
Throw String (or equivalent) exceptions from within the classes to ensure that invalid objects cannot be created.
F. In your main:
Declare a primitive array of 5 Currency references (for C++ programmers, array of 5 Currency pointers).
Ask the user for 5 decimal numbers to be input - for each of the inputs you will create one Money object to be stored in the array.
Once the array is filled, perform the following five operations:
Print the contents of the array of objects created in long form, i.e. if the user entered "2.85" for the first value, it should be printed as "2 Dollar 85 Cent".
Add the first Money object to the second and print the resulting value in long form as above.
Subtract the first Money object from the third and print the resulting value in long form as above.
Compare the first Money object to the fourth and print whether both objects are equal or not using long form for object values.
Compare the first Money object to the fifth and print which object value is greater than the other object value in long form.
All operations in the main should be performed on Currency objects demonstrating polymorphism.
Remember to handle exceptions appropriately.
There is no sample output - you are allowed to provide user interactivity as you see fit.

Write a program that creates a Date object, sets its elapsed time to 10000, 100000, 1000000, 10000000, 100000000, 1000000000, 10000000000, and 100000000000, and displays the date and time using the toString()
Answer:
Explanation:
The following Java program creates various Date objects for each one of the provided milliseconds in the question. Then it calls the toString() method on each one. The last two milliseconds were not included because as a long variable they are too big for the Date object to accept. The code has been tested and the output is shown in the image below.

The process of providing only the essentials and hiding the details is known as _____. a. algorithm b. data structure c. abstraction d. optimization
The process of providing only the essentials and hiding the details is known as abstraction.
What is abstraction?Abstraction in its main sense is a conceptual process wherein general rules and concepts are derived from the usage and classification of specific examples, literal ("real" or "concrete") signifiers, first principles, or other methods.
"An abstraction" is the outcome of this process—a concept that acts as a common noun for all subordinate concepts and connects any related concepts as a group, field, or category.
Conceptual abstractions may be formed by filtering the information content of a concept or an observable phenomenon, selecting only those aspects which are relevant for a particular purpose. For example, abstracting a leather soccer ball to the more general idea of a ball selects only the information on general ball attributes and behavior.
Therefore, The process of providing only the essentials and hiding the details is known as abstraction.

If we were ever to use this pizza ordering program again, we would want to use mainline logic to control its execution. The way it is written, it will automatically execute as soon as it is imported.
Re-write this program, enclosing the top level code into the main function. Then execute the main function. Enter appropriate input so the output matches that under Desired Output.
# Define Function
def pizza(meat="cheese", veggies="onions"):
print("You would like a", meat, "pizza with", veggies)
# Get the User Input
my_meat = input("What meat would you like? ")
my_veggies = input("What veggie would you like? ")
# Call the Function
pizza(meat=my_meat, veggies=my_veggies)
desired output:
What meat would you like? cheese
What veggie would you like? onions
You would like a cheese pizza with onions
2) We want to generate 5 random numbers, but we need the random module to do so. Import the random module, so the code executes.
# Define main function
def main():
print("Your random numbers are:")
for i in range(5):
print(random.randint(1, 10))
# Call main function
