Relational database systems use constraints to ensure that relationships between coupled tables remain consistent. Constraints are rules that define the allowable data values, data types, and relationships between tables.
By enforcing constraints, relational database systems can prevent data inconsistencies, maintain data integrity, and ensure the accuracy of the data. Examples of constraints include primary keys, foreign keys, unique constraints, and check constraints. These constraints help to maintain the referential integrity of the data, ensuring that data in one table is related to the data in other tables as intended.

A. Executive management
B. Impact analysis
C. Scheduling
D. Technical constraint identification
The key aspect of requirements management that addresses the formal approach to assessing the potential pros and cons of pursuing a course of action is B)Impact analysis
Why Impact Analysis?
Impact analysis is a crucial aspect of requirements management, as it helps project teams to evaluate the potential benefits and drawbacks of proposed changes or solutions. This involves analyzing how the change or solution may impact various aspects of the project, such as cost, schedule, resources, stakeholders, and existing systems. By conducting a thorough impact analysis, project teams can make informed decisions about whether to pursue a particular course of action or to revise the requirements or solution.
In addition to impact analysis, other key aspects of requirements management include technical constraint identification, scheduling, and executive management. Technical constraint identification involves identifying any technical limitations or restrictions that may impact the feasibility or viability of the proposed solution. Scheduling involves defining and managing the timelines and milestones for the project, including the requirements gathering and analysis phase. Executive management is responsible for overseeing the project and ensuring that it aligns with the goals and priorities of the organization.
Overall, effective requirements management is essential for ensuring that the project meets the needs and expectations of the stakeholders and delivers the desired outcomes. By utilizing a systematic approach to requirements management, project teams can improve the quality of the project and minimize risks and issues that may arise during the project lifecycle.

A highway is 80km in length 3/4 of the Highway is paved. How many km of the Highway is
paved
Answer: 60km
Explanation:
Since the highway is 80km in length and 3/4 of the highway is paved. Therefore, the number of km of the highway that is paved will be gotten as:
= Fraction of highway that's paved × Length of highway
= 3/4 × 80km
= 60km
Therefore, 60km of the highway is paved.
A certain computer system implements a paged virtual memory system. Each process has a 16MB virtual memory space. The page size is 1024 bytes. The physical memory size for the system is 2MB.
How many bits are in a virtual memory address?
The total number of bits required to address a virtual memory address is: 14 bits (page number) + 10 bits (offset within page) = 24 bits
To calculate the number of bits in a virtual memory address, we need to first determine the number of pages in the virtual memory space. Since the virtual memory space is 16MB and the page size is 1024 bytes, we can calculate the number of pages as follows: 16MB / 1024 bytes per page = 16,384 pages
We need to determine the number of bits required to address each page. Since there are 16,384 pages, we need log2(16,384) = 14 bits to address each page. Finally, we need to add the number of bits required to address the offset within a page. Since the page size is 1024 bytes, we need log2(1024) = 10 bits to address the offset within a page.

Keyboard shortcuts are keys or key combinations that offer an alternative method of performing tasks that you would ordinarily perform with a mouse.
What is the function of shortcut key?Using shortcut keys in computer applications can help you navigate and carry out tasks more quickly and easily. Alt (on IBM-compatible computers), Command (on Apple computers), Ctrl, or Shift combined with another key is used to execute shortcut keys.The name "shortcut" comes from the fact that keyboard shortcuts are frequently used to speed up routine tasks by condensing input sequences to a few keystrokes. Most keyboard shortcuts require the user to press and hold a number of keys simultaneously or a series of keys one after another in order to distinguish them from regular keyboard input.Keyboard shortcuts are stringed-together keystrokes that let you complete a task fast. They are helpful and frequently excellent time savings.Given shortcuts :
CTRL + A = Select all document content.
CTRL + Page Up = Move to the previous sheet in the workbook.
CTRL + E = Aligns the line or selected text to the center of the screen.
CTRL + F = To find a word or words on a page.

In a file called pp8d.cpp, write a function that has three parameters, all C-strings. The first parameter is a phrase with an asterisk in it such as "I * cats!". The second parameter is a word such as "love" that will be put in place if the asterisk. The third string will hold the new phrase, "I love cats!". Follow these steps:
- Initialize the third parameter to the empty string
- Find the index where the asterisk is in the first string
- Use either strncat or strncpy to create "I " in the third parameter. Recall that strncpy does NOT put the null character at the end of the string it creates.
- Use strcat to concatenate the word to the third parameter so it contains "I love"
- Use srtcat to concatenate the rest of the first parameter to the third so that it now contains "I love cats!"
- Write a main driver that asks the user for a phrase with an asterisk and a word. It calls the function then prints the new phrase.
) Execute your program and compare its output to the Expected Output column.
The function in pp8d.cpp takes three parameters, two C-strings and a phrase with an asterisk. It uses strcat to concatenate the word in the second parameter to the third parameter, replacing the asterisk in the phrase with the word, resulting in a new phrase. The main driver asks the user for input and calls the function to print the new phrase.
To explain further, the function uses the strcat function from the string.h library to concatenate the word to the third parameter, resulting in "I love cats!". The function then returns the new phrase. In the main driver, the user is prompted to enter a phrase with an asterisk and a word, which are passed as arguments to the function. The function is called and the new phrase is printed to the console. This program is a simple example of string manipulation and function calling in C++.
