3. Virtual database.
4. Distributed database.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
There are four (4) major types of database in a data warehouse and these are;
1. Multistage database: used for concise as well as detailed historical data. It provides summarized data which can be used by an employee for short-term decision making.
2. Stationary database: used where access to data is rare i.e business firms who do not access data frequently. In order to use this database, the users must have an access to metadata store and thus, directly having access to the data on a source system.
3. Virtual database: used for accessing data in diverse applications using middleware. This type of database is dependent on having access to information on various databases.
4. Distributed database: used by an organization that runs several businesses. Therefore, this type of database are usually located or situated in various geographical regions.

How can you compute, the depth value Z(x,y) in
z-buffer algorithm. Using incremental calculations
find out the depth value Z(x+1, y) and Z (x, y+1).
(2)
Answers
The Depth-buffer approach, usually referred to as Z-buffer, is one of the methods frequently used to find buried surfaces. It is a method in image space and pixel.
Thus, The pixel to be drawn in 2D is the foundation of image space approaches and Z buffer. The running time complexity for these approaches equals the product of the number of objects and pixels.
Additionally, because two arrays of pixels are needed—one for the frame buffer and the other for the depth buffer—the space complexity is twice the amount of pixels.
Surface depths are compared using the Z-buffer approach at each pixel location on the projection plane.
Thus, The Depth-buffer approach, usually referred to as Z-buffer, is one of the methods frequently used to find buried surfaces. It is a method in image space and pixel.

what is the symbol for population mean
Answers
The symbol for population mean is μ (mu).
The symbol μ (mu) is used to represent the population mean in statistics. The population mean is a measure of central tendency that represents the average value of a variable in the entire population.
It is calculated by summing up all the values in the population and dividing by the total number of observations.
The use of the Greek letter μ as the symbol for population mean is a convention in statistics. It helps to distinguish the population mean from other measures of central tendency, such as the sample mean .
The population mean provides valuable information about the average value of a variable in the entire population, which can be useful for making inferences and drawing conclusions about the population as a whole.
The population mean is a useful statistic because it provides a single value that summarizes the central tendency of the variable in the population. It helps researchers and statisticians understand the typical or average value of the variable and make comparisons or draw inferences about the population as a whole.
It's important to note that the population mean is based on data from the entire population, which is often not feasible or practical to obtain in many cases. In such situations, researchers often rely on samples to estimate the population mean.

In JAVA with comments: Consider an array of integers. Write the pseudocode for either the selection sort, insertion sort, or bubble sort algorithm. Include loop invariants in your pseudocode.
Answers
Here's a Java pseudocode implementation of the selection sort algorithm with comments and loop invariants:
```java
// Selection Sort Algorithm
public void selectionSort(int[] arr) {
int n = arr.length;
for (int i = 0; i < n - 1; i++) {
int minIndex = i;
// Loop invariant: arr[minIndex] is the minimum element in arr[i..n-1]
for (int j = i + 1; j < n; j++) {
if (arr[j] < arr[minIndex]) {
minIndex = j;
}
}
// Swap the minimum element with the first element
int temp = arr[minIndex];
arr[minIndex] = arr[i];
arr[i] = temp;
}
}
```The selection sort algorithm repeatedly selects the minimum element from the unsorted part of the array and swaps it with the first element of the unsorted part.
The outer loop (line 6) iterates from the first element to the second-to-last element, while the inner loop (line 9) searches for the minimum element.
The loop invariant in line 10 states that `arr[minIndex]` is always the minimum element in the unsorted part of the array. After each iteration of the outer loop, the invariant is maintained.
The swap operation in lines 14-16 exchanges the minimum element with the first element of the unsorted part, effectively expanding the sorted portion of the array.
This process continues until the entire array is sorted.
Remember, this pseudocode can be directly translated into Java code, replacing the comments with the appropriate syntax.

A program is required to compute the cost of a car trip. The required input values are:
Litres per 100km
Distance travelled
Cost per litre of petrol
The output value is the total cost of the trip.
Answers
The program required to compute the above in Phyton is given below.
What is the program that computes the cost of a car trip using the above parameters?the required program is given as follows;
# Input values
litres_per_100km = float(input("Enter the fuel efficiency of your car in litres per 100km: "))
distance_travelled = float(input("Enter the distance travelled in km: "))
cost_per_litre = float(input("Enter the cost per litre of petrol in your local currency: "))
# Calculate the total litres of petrol used
litres_used = (litres_per_100km / 100) * distance_travelled
# Calculate the total cost of the trip
total_cost = litres_used * cost_per_litre
# Display the result
print(f"The total cost of the trip is {total_cost:.2f} {currency_symbol}")
Note that this program prompts the user to enter the fuel efficiency of their car in litres per 100km, the distance travelled in km, and the cost per litre of petrol in their local currency.
It then calculates the total litres of petrol used by multiplying the fuel efficiency by the distance travelled, and calculates the total cost of the trip by multiplying the litres used by the cost per litre.
Finally, it displays the result to the user, rounded to two decimal places. Note that the currency symbol can be added to the output string depending on the user's location.
