Indexed sequential access, an index is more useful when the number of record is

RoseWind [281]

With indexed sequential access, an index is more useful when the number of record is large. Index is needed to order the elements of the data base by specific index. For example you have client database. You have city index in your data base and you can order your clients by the city where they live.

Using the knowledge of computational language in JAVA it is possible to describe since s is null, indexof throws an nullpointer error for s. comment out the first if statement and run the program again. the second if statement avoids the error with shortcircuit evaluation.

In python please:

Vikki [24]

Answer:

if 'marsupial' in dictionary:

del dictionary['marsupial']

else:

print("The key marsupial is not in the dictionary")

Explanation:

So you can use the keyword "in" to check if a certain key exists.

So the following code:

if key in object:

# some code

will only run if the value of "key" is a key in the object dictionary.

So using this, we can check if the string "marsupial' exists in the dictionary.

if 'marsupial' in dictionary:

# code

Since you never gave the variable name for the variable that references a dictionary, I'm just going to use the variable name "dictionary"

Anyways, to delete a key, there are two methods.

del dictionary[key]

dictionary.pop(key)

Both will raise the error "KeyError" if the key doesn't exist in the dictionary, although there is method with pop that causes an error to not be raised, but that isn[t necessary in this case, since you're using the if statement to check if it's in the dictionary first.

So I'll just use del dictionary[key] method here

if 'marsupial' in dictionary:

del dictionary['marsupial']

else:

print("The key marsupial is not in the dictionary")

The last part which I just added in the code is just an else statement which will only run if the key 'marsupial' is not in the dictionary.

Four actions that can be implemented on a database to autocorrect violations of referential integrity, and the outcomes of the a

Paraphin [41]

Answer:

Follows are the matching to this question:

$Option \ a \to \ Option \ 3\\\\Option \ b \to \ Option \ 4\\\\Option \ c \to \ Option \ 1\\\\Option \ d \to \ Option \ 2\\$

Explanation:

While time-consuming or prone to errors mechanical adjustments to both the referential, databases could be configured with four measures to engine violations. The restricted action causes the insert, update, and removes to only be denied. Set Null to NULL sets the invalid external key, whereas Set Default to a specific core consideration specified in SQL sets a default foreign key. Its Cascade operation spreads the main changes in external keys.
