Answer: False
Explanation:
This means that the mappings between the two schemas may be specified in either one of these languages.In most relational DBMSs today, there is no specific language that performs the role of SDL. Instead, the internal schema is specified by a combination of functions, parameters, and specifications related to storage. These permit the DBA staff to control indexing choices and mapping of data to storage
Answer:
def barGraph(w, h, data):
# creating Canvas
paper = Canvas(w, h)
# defining variables
largest = max(data) # largest element in data
length = len(data) # length of data list
barWidth = 0.8 * w / length # length of each bar of the histogram
maxBarHeight = 0.8 * h # maximum height of each bar of the histogram
minBarHeight = maxBarHeight / largest # minimum height of each bar
# Starting points
x = 0.1 * w
y = 0.9 * h
# looping through the list
for i in data:
currBarHeight = minBarHeight * i # current bar height
x1 = x + barWidth
y1 = y - currBarHeight
# creating the rectangle, and adding it to the bar graph
bar = Polygon( Point(x,y), Point(x,y1), Point(x1,y1), Point(x1,y) )
bar.setFillColor('grey')
paper.add(bar)
x = x1
# returning the canvas
return paper

Explanation:
Answer:
The equivalent if statements is:
ranforce = randi([0, 12]);
if (ranforce == 0)
disp('There is no wind')
else if(ranforce>0 && ranforce <7)
disp('There is a breeze')
else if(ranforce>6 && ranforce <10)
disp('This is a gale')
else if(ranforce>9 && ranforce <12)
disp('It is a storm')
else if(ranforce==12)
disp('Hello, Hurricane!')
end
Explanation:
<em>The solution is straight forward.</em>
<em>All you need to do is to replace the case statements with corresponding if or else if statements as shown in the answer section</em>
Here’s a explanation. A cameras exposure is the amount of light that goes through the sensor. So for example, taking a photo outside in the daytime will be more clear because more exposure hits the sensor, but taking of photo outside after dark will be more blurry and probably won’t look to good because without the exposure it needs, it can’t get enough light to show a picture. Hope this helps
