Relationships in a relational database are defined by joining common data stored in records from different tables, So the given statement is false.
What is the difference between spreadsheet and database?Structured data is data that follows a predefined data model and is thus easy to analyze. Structured data follows a tabular format with relationships between rows and columns. Excel files and SQL databases are common examples of structured data.A spreadsheet does not have defined field types, whereas a database does. A database, unlike a spreadsheet, employs a standardized query language (such as SQL). A database can store much more data than a spreadsheet.The primary technical distinction between a spreadsheet and a database is how data is stored. Data is stored in a cell in a spreadsheet and can be formatted, edited, and manipulated within that cell. Cells in a database contain records from external tables.To learn more about spreadsheet refer to :

explain the two basic approches that use the concept of pipeling at data link layer
The two basic approaches that use the concept of pipeline at data link layer is given below
Asynchronous pipelineSynchronous pipelineWhat is the data link layer?In the data link layer of the OSI model, the concept of pipelining can be used in two basic approaches:
Asynchronous pipeline: In this approach, a pipeline is used to transmit data in an asynchronous manner, meaning that the data is transmitted without a predetermined clock signal.
Synchronous pipeline: In this approach, a pipeline is used to transmit data in a synchronous manner, meaning that the data is transmitted using a predetermined clock signal.
Therefore, Both approaches can be used to improve the efficiency of data transmission by allowing multiple pieces of data to be transmitted at the same time. However, the synchronous pipeline approach may be more complex to implement and requires more accurate timing, as the clock signal must be carefully coordinated with the transmission of data.

Implement the function permutations() that takes a list lst as input and returns a list of all permutations of lst (so the returned value is a list of lists). Do this recursively as follows: If the input list lst is of size 1 or 0, just return a list containing list lst. Otherwise, make a recursive call on the sublist l[1:] to obtain the list of all permutations of all elements of lst except the first element l[0]. Then, for each such permutation (i.e., list) perm, generate permutations of lst by inserting lst[0] into all possible positions of perm.
>>> permutations([1, 2])
[[1, 2], [2, 1]]
>>> permutations([1, 2, 3])
[[1, 2, 3], [2, 1, 3], [2, 3, 1], [1, 3, 2], [3, 1, 2], [3, 2, 1]]
>>> permutations([1, 2, 3, 4])

[1, 3, 2, 4], [3, 1, 2, 4], [3, 2, 1, 4], [3, 2, 4, 1],

[1, 4, 3, 2], [4, 1, 3, 2], [4, 3, 1, 2], [4, 3, 2, 1]]
Answer:
def permutations(myList: list)-> list:
if len(myList) <= 1:
return [myList]
perm = []
for i in range(len(myList)):
item = myList[i]
seglists = myList[:i] + myList[i+1:]
for num in permutations(seglists):
perm.append([item] + num)
return perm
data = [1,2,3]
result = permutations(data)
print(result)
Explanation:
The program defines a python function that returns the list of permutations. The program checks if the length of the input list is less than or equal to one. The function declaration identifies the input and output as lists.
The for loop iterate through the list and the permutations are saved in an empty list in the next loop statement. At the end of the program, the list of lists is returned.

Introduction This lab uses things you learned in your introductory programming class. Some of those things are: - constants - random numbers - overloaded methods - passing/returning arrays - filling and printing a one-dimensional array - filling and printing a two-dimensional array Just for fun, we'll include a GUI to visualize your
QR
code! Specifications You will create a class
QRC
code that fills a grid with values that can be interpreted to visualize a QRCode image. (This is not a true QRCode but a pattern similar to one.) Required elements 1. QRCode class methods are instance methods. 2. Your program will contain a main method that creates an instance of QRCode and calls its methods such that the result output is a grid dim
x
dim with Finder values in the upper left, lower left, and upper right corners. 3. The dimension for the grid and the seed for the Random object must be passed in from the command line. 4. If two arguments are not passed in from the command line, your program should use constants defined below: - DEFAULT_DIMENSION 30 - DEFAULT_SEED 160 5. Methods that return a value must pass unit tests that will not be made available for view, that is, those methods should be thoroughly tested by you prior to submitting your program. 6. Only the print methods may have output to the console. 7. Class members must conform to the UML diagram below: Q=============== Class Name ================ QRCode ============ Private Variables ============ - grid : int[] [] ============ Public methods ============== + createPattern(dim : int, seed : int) : int[] + setGrid(dim : int, pattern : int []) : void + getGrid() : int[][] + setFinder(xpos : int, yPos : int) : void + addFinders(dimension : int) : void - fillSquare(startX : int, startY : int, width : int, color: int) : void // possible helper method + print() : void + print (pattern : int [] ) : void + print(matrix : int[][]) : void Method specifications You will create an outline called a stub program where the method headers are the only implemented part of the class and all methods only return default values. In a later lab, you will complete the class to have full functionality. You can get all the information you need from the UML outline above. Testing Things to test for are the correct number/type of arguments, and the return values (void or null). Grading Your code will be evaluated for correctness of being able to call each function and the default return value (if any) will be checked.

To create a class QRC, code that fills a grid with values that can be interpreted to visualize a QRCode image, check the code given below.
What is class?A class in object-oriented programming is a blueprint for creating objects (a specific data structure), providing initial values for state (member variables or attributes), and implementing behaviour (member functions or methods).
//CODE//

Also, ways to start a rough list:
int arr_name [] [] = new int [] [] { new int [] {10, 20, 30, 40}, new int [] {50, 60, 70, 80, 90, 100}, new int [] {110, 120} }; OR
int [] [] arr_name = { new int [] {10, 20, 30, 40}, new int [] {50, 60, 70, 80, 90, 100}, new int [] {110, 120} }; OR
int [] [] arr_name = { {10, 20, 30, 40}, {50, 60, 70, 80, 90, 100}, {110, 120} }; The following are the Java applications for displaying the above concept.
// 2-D rough list display program in Java class Main { public static void main (String [] args) { // Announces the same 2-D members with 2 rows int arr [] [] = new int [2] [];
// To make the above list Jagged

// The second row has 2 columns arr [1] = new int [2];
// Starting list int count = 0; because (int i = 0; i <arr.length; i ++) because (int j = 0; j <arr [i] .duration; j ++) arr [i] [j] = count ++;
// Displays the values of the 2D Jagged array System.out.println ("2D Jagged Array Contents"); because (int i = 0; i <arr.length; i ++) { because (int j = 0; j <arr [i] .duration; j ++) System.out.print (arr [i] [j] + ""); System.out.println (); } } } Output Content of 2D Jagged Array 0 1 2 3 4 The following is another example where the i line has i-columns, that is, the first row has 1 element, the second row has 2 elements, and so on.

Responsive.
Explanation:
HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.
Generally, all HTML documents are divided into two (2) main parts; body and head. The head contains information such as version of HTML, title of a page, metadata, link to custom favicons and CSS etc. The body of the HTML document contains the contents or informations of a web page to be displayed.
The responsiveness of a webpage is an ability of the design to respond to the end user's digital device and screen size.
In Computer programming, a responsive web design makes it possible for various websites to change layouts in accordance with the user's digital device and screen size.
This ultimately implies that, a responsive design is a strategic approach which enables websites to display or render properly with respect to the digital device and screen size of the user.
