Answers

Answer 1

The relational model's foundation is a mathematical concept known as a relation.

The relational model's foundation is a mathematical concept known as a relation. It was created by E.F. Codd in 1970, and it describes how data is structured and accessed in a database management system (DBMS). The primary concept underlying the relational model is the idea of a relation.A relation is a two-dimensional table made up of rows and columns. Each row corresponds to a unique combination of data items, while each column represents a particular attribute of the data. A column's name identifies its attributes, and each cell of the table contains a single value.

Furthermore, a relational model database is made up of several tables that are related to one another in a variety of ways.

10.17 PROGRAM 2: Airline Seat Booking Program
C++ PLEASE!
This assignment must be completed on your own. Students may only ask for help from the TAs or instructors. If you have questions about the collaboration policy, please ask your instructor.
An airline uses a computer system to maintain flight sales information. For planning purposes, the airline must know what seats are on the plane, what seats are available, what seats are booked, and must have the ability to change the status of a seat from available to booked and vice versa. For this assignment, you will be implementing some of the functionality of the airline computer system. You will need to implement the following steps.
(1) Create the initial vectors for seats on the plane and seat status. You may assume that the plane has rows 1 through 5 and each row has seat A through E. The seat status is a 0 if the seat is available or a 1 if the seat is booked, and, therefore, not available.
(2) Implement a menu of options for the user. Following the initial setup of the vectors, the program outputs the menu. The program should also output the menu again after a user chooses an option. The program ends when the user chooses the option to Quit.
Ex:
Menu options:
1. Display All Seats Status:
2. Total Number of Available Seats:
3. Display Available Seats: 4. Book Seat:
5. Cancel Seat:
6. Change Seat:
7. Quit:
Please select an option: (3) Implement the "Display All Seats Status" menu option. Be sure to write a separate function for each menu option.
Ex:
Seat Status
1A 0
1B 0
1C 0
1D 0
1E 0
2A 0
...
(4) Implement the "Total Number of Available Seats" menu option.
Ex:
Number of available seats: 20
(5) Implement the "Display Available Seats" menu option. This function should show a list of available seats.
Ex:
Available seats:
1A
1B
1C
1D
1E
2A
...
(6) Implement the "Book Seat" menu option. This function should take in the seat to book and then should change the status of that seat to unavailable. After the function, the status of all seats should be displayed.
Ex:
Enter seat to book: 1A
Seat Status
1A 1
1B 0
1C 0
1D 0
1E 0
2A 0
...
(7) Add logic to the "Book Seat" menu option that will not allow the user to book a seat that is already booked.
Ex:
Enter seat to book: 1A
That seat is already taken.
Enter seat to book: 1B
Seat Status
1A 1
1B 1
1C 0
1D 0
1E 0
2A 0
...
(8) Implement the "Cancel Seat" menu option. This function should take in the seat to cancel and then should change the status of that seat to available. After the function, the status of all seats should be displayed.
Ex:
Enter seat to cancel: 1A
Seat Status
1A 0
1B 0
1C 0
1D 0
1E 0 2A 0
...
(9) Implement the "Change Seat" menu option. This function should take in the seat to cancel , the seat to book, and then should change the status of those seats. After the function, the status of all seats should be displayed.
Ex:
Enter seat to cancel: 1A
Enter seat to book: 1B

the d flip-flop can be build from two back-to-back s/r latches controlled by complementary clocks. question 20 options: true false

Answers

The given statement is true. The D flip-flop can be constructed using two back-to-back SR latches, which are controlled by complementary clocks.

Know what is a flip-flop! A flip-flop is a bistable device that can store one bit of memory. The input, output, clock, and power connections are found on the flip-flop. Each flip-flop has two output states, or a binary state, hence it is called a bistable device. They can be used to store binary information, hold a single bit of memory, or delay the input signal. What is an SR latch! A Set-Reset latch is a type of latch that is commonly used in digital electronics. It is made up of two NOR gates and has two inputs, namely, Set (S) and Reset (R). The latch's output is one of two stable states, namely Set and Reset. The input states have no impact on the output, implying that the latch can operate as a memory device without external clocking.

What is a D flip-flop! A D flip-flop is a clocked flip-flop that is used to store one bit of data. It is used to store the current state of the input D when the clock signal C changes from low to high. The output of the D flip-flop is one of two states, which are determined by the present input and the previous output. The output is determined by the logic state at the D input, which is the data input, when the clock signal transitions from low to high.

Conversely, a project that is not open innovation relies primarily on internal resources and expertise.

Here are some characteristics of an open innovation project:

Collaboration: Open innovation projects involve collaboration between internal teams and external partners such as customers, suppliers, academic institutions, startups, and other companies.

Sharing of knowledge: An open innovation project requires sharing of knowledge, information, and expertise between the internal and external parties.

Involvement of external parties: In an open innovation project, external parties are actively involved in the innovation process, from ideation to commercialization.

Innovation ecosystem: An open innovation project is part of a larger innovation ecosystem that fosters the exchange of ideas, knowledge, and expertise.

Access to resources: An open innovation project provides access to external resources such as funding, facilities, equipment, and talent.

In contrast, a project that is not open innovation is typically driven by internal resources and expertise. Internal teams are responsible for all aspects of the innovation process, and external parties are not involved in any significant way.

In summary, an open innovation project involves collaboration, sharing of knowledge, involvement of external parties, an innovation ecosystem, and access to external resources.

Suppose a new technology X is partially backwards-compatible with an older technology Y so that any person who adopts X still receives some benefits from interacting with friends using Y ( and vice versa). Consider the following payoff matrix which models this situation of partial compatibility. Player B X Y
Player A X (5,5) (3,2)
Y (2,3) (4,4)
Suppose that technology X is spreading through a network of users of Y. The payoff to each individual is determined by playing the above coordination game with each of their neighbors in the network. Does this coordination game also result in a "threshold contation"? That is, if p is the fraction of node A's neighbors that adopt X, is there some critical value q such that A should adopty X, when p is at least q, and remain with Y when p is less than q? If so, determine the value of q. If not, explain why the threshold does not exist

Answers

Yes, this coordination game also results in a threshold contagion.

To determine the critical value q, we can use the concept of the best response. The best response for player A is to adopt X if and only if the expected payoff from adopting X is greater than the expected payoff from remaining with Y. We can calculate the expected payoffs as follows:

If A adopts X:

A's payoff when playing against a neighbor who uses X is 5 with probability p and 3 with probability (1-p)

A's payoff when playing against a neighbor who uses Y is 2 with probability p and 4 with probability (1-p)

Therefore, A's expected payoff from adopting X is:

5p + 3(1-p) with probability p

2p + 4(1-p) with probability (1-p)

If A remains with Y:

A's payoff when playing against a neighbor who uses X is 2 with probability p and 4 with probability (1-p)

A's payoff when playing against a neighbor who uses Y is 4 with probability p and 4 with probability (1-p)

Therefore, A's expected payoff from remaining with Y is:

2p + 4(1-p) with probability p

4 with probability (1-p)

To find the critical value q, we need to find the value of p at which A is indifferent between adopting X and remaining with Y. In other words, we need to find the value of p for which the expected payoffs from adopting X and remaining with Y are equal.

Setting the two expected payoffs equal to each other and solving for p, we get:

5p + 3(1-p) = 2p + 4(1-p)

Solving for p, we get p = 1/3.

Therefore, if at least one-third of A's neighbors adopt X, then A should adopt X as well. If fewer than one-third of A's neighbors adopt X, then A should remain with Y.

Yes, if a relational database table is in Boyce-Codd normal form (BCNF), it is also in all of a., b., and c.

BCNF is a normal form in database normalization that further refines the results of the Third Normal Form (3NF). It is an advanced form of database normalization, and it applies to the design of relational databases. It is an important tool for database designers, as it helps to reduce data redundancy and improves the integrity of the database.

In order to be in BCNF, a database must meet the following criteria: (1) every determinant must be a candidate key, (2) every non-prime attribute must be fully functionally dependent on a single determinant, and (3) all transitive dependencies must be eliminated. A database that meets these criteria is said to be in BCNF and is also in all of a., b., and c.

In conclusion, if a relational database table is in BCNF, then it is also in all of a., b., and c. BCNF is a higher form of normalization that eliminates transitive dependencies and improves database integrity.

to qualify a column name, precede the name of the column with the name of the table, followed by a(n) .

Answers

To qualify a column name, precede the name of the column with the name of the table, followed by a period (.).

In a database, it is common to have multiple tables that are related to each other. When querying data from these tables, it is important to specify which table a particular column belongs to, especially if the column name appears in multiple tables.

This is known as the "table alias" or "table qualifier" and is used to specify which table the column belongs to, especially when multiple tables are being joined in a query. For example, if you have two tables named "Customers" and "Orders", and both tables have a column named "ID", you could specify which table's ID column you want to select by using the table qualifier: "Customers.ID" or "Orders.ID".
