The security for the database should be more stringent than the security for the rest of the system, as it contains the critical information that needs to be protected.

The database security should be designed to ensure the confidentiality, integrity, and availability of the data. This means that access to the database should be limited to authorized users and activities should be audited to prevent unauthorized access or modifications.

For web-based data designs, the security of the database is even more critical, as the data is accessed over the internet and is therefore more vulnerable to attacks. Web-based data designs need to incorporate additional security measures such as user authentication, access controls, firewalls, intrusion detection, and prevention systems to protect the database from cyber threats.

The correct statement about Solar cells  is Energy from the sun might be greater than the energy needs of the house, so some energy will be stored and/or wasted. Option A

This is because the amount of energy produced by solar cells depends on factors such as the intensity of sunlight, the surface area of the solar panels, and the efficiency of the conversion process.

These factors can vary over time and affect the amount of energy that is generated. Additionally, the energy needs of a household can vary depending on factors such as the time of day, season, and overall energy consumption patterns.

Therefore, it is possible that at times the energy produced by solar cells may exceed the energy needs of the house, and any excess energy would need to be stored or wasted.

In the given syntax, the column "I-city" in the "where" clause is the best candidate for an index.

The selectivity of an index refers to the percentage of rows in the table that match a specific value in the indexed column. Since the query filters by the value of the "I-city" column, creating an index on this column would improve the query's performance by allowing the database to quickly locate and retrieve the matching rows.

In this case, if a significant portion of the Instructors table has a "Houston" value in the "I-city" column, creating an index on this column would result in a high selectivity, making it a good candidate for indexing.

Computers have had a profound impact on society, particularly in the areas of privacy and quality of life. While computers have made many aspects of our lives easier and more convenient, they have also introduced new challenges and concerns.

One of the biggest societal implications of computers is the issue of privacy. As computers have become more ubiquitous and more connected, the amount of personal information that is being collected and shared has increased significantly. This has raised concerns about who has access to our data and how it is being used. There is also a risk of identity theft and other types of cybercrime, which can have serious consequences for individuals and society as a whole.

Another important societal implication of computers is their impact on quality of life. On the one hand, computers have made many aspects of our lives easier and more convenient. For example, we can now work remotely, shop online, and connect with friends and family from anywhere in the world. However, there is also concern that computers and technology are making us more isolated and less connected to each other. Some argue that social media and other digital technologies have made it more difficult for people to form meaningful relationships and engage in face-to-face communication.

Additionally, computers have also had an impact on the job market. While computers and automation have made many tasks more efficient and cost-effective, they have also led to job displacement and the need for workers to constantly update their skills in order to remain competitive. This can lead to economic and social inequality, particularly for those who are less able to adapt to new technologies.

In summary, computers have had a significant impact on society, both positive and negative. While they have made many aspects of our lives easier and more convenient, they have also introduced new challenges and concerns, particularly with regard to privacy and quality of life. It is important for individuals and society as a whole to carefully consider the implications of new technologies and work to mitigate any negative consequences.

The Fourth Industrial Revolution (4IR) is the ongoing transformation of the traditional manufacturing and industrial sectors through the integration of advanced technologies such as artificial intelligence, the Internet of Things (IoT), robotics, big data, and automation.

The four most important variables that will change the way we live and work in the 4IR are:

Automation: The increased use of robotics and automation will revolutionize the manufacturing industry and lead to more efficient and cost-effective production processes. This could lead to significant job displacement, but it could also create new opportunities for workers with new skills.

Big Data: The collection and analysis of massive amounts of data will allow businesses to gain new insights into customer behavior, supply chain efficiency, and product performance. This could lead to more personalized and efficient services, but also raise concerns around privacy and data security.

Artificial Intelligence: The use of advanced algorithms and machine learning will enable machines to perform complex tasks previously thought to require human intelligence. This could lead to more efficient and effective decision-making, but also raise concerns around the impact on jobs and the ethical implications of AI decision-making.

Internet of Things: The proliferation of connected devices will enable the automation and integration of various systems and processes, leading to more efficient and effective resource utilization. This could lead to significant improvements in healthcare, transportation, and energy management, but also raise concerns around privacy and security risks.

Overall, the 4IR is expected to bring significant changes to our economy, society, and daily lives, with both opportunities and challenges that we will need to navigate as we move forward.

Below is a possible implementation of the Das/h/It function based on the instructions in the image attached.

We use st/r/p/brk to find the first occurrence of an alpha character in DashPhrase that is also in the alphabet Alphabet. We replace that character with a dash and call strpbrk again to find the next occurrence of an alpha character.

Note that we use the dereference operator * to modify the character pointed to by /Repl/aceI/t. Also note that strpbrk returns a pointer to the first occurrence of any character in the search string, so we need to increment Re/plac/e/It by 1 before passing it to str/p/brk again to avoid finding the same character again.

Note that an example C++ code that counts the number of occurrences of a given character in a string:

#include <iostream>

#include <string>

int main() {

 char target_char;

 std::string input_str;

 std::getline(std::cin, input_str);

 std::cin >> target_char;

   if (c == target_char) {

     count++;

   }

 }

 std::cout << count << " " << target_char << "'s" << std::endl;

 return 0;

}

This code reads a line of input from the user and a target character to search for.


It then iterates through each character in the input string and increments a counter if the character matches the target character. Finally, it prints out the count and the target character. Note that this code is case-sensitive.

Therefore, In the main program, we create an array of Employee objects and use a loop to get input from the user for three employees. We create Employee objects with the input data and append them to the employees array. Finally, we use another loop to print the payment of each employee by calling the getPayment() method on each Employee object.
