Answer:
Read the file and save it to a variable as a string, split the string variable and cast it to a set object using the set function to get the unique words in the file. Then use the max function with the key attribute to use regular expression module "re" to compare the first letter of each item to return in a list comprehension or append to a list.
Explanation:
The open function is used to import a file in python, the split string method splits the string to a list of items and the set function removes any duplicates of a word or item.
Using the for loop statement, iterate over the items and compare and return the items in alphabetical order with the 're' search method getting the item with uppercase letters with higher precedence than lowercase.
Answer:b) Master reference file(MRF)
Explanation: Master reference file is the collection of data that persist the schedules records for the maintenance and administration. It is the UDC version tool .
It helps in the managing the data content present in the database, archiving and tracing any changes on the database over certain time.Master data management is the managing of data's integrity .It send the collected critical data to the master reference files.
Other given options are incorrect because backup file is for creating data backup, central directory is record of the data of users and other information and data silo is kind of fixed data having the governance of any organization.Thus, these factors don't help in the critical information management.Thus, the correct option is option(b).
A many-to-many relationship between classes A and B (where the maximum multiplicity on both sides of the association is *) is implemented by posting foreign keys in both A and B is a false statement.
<h3>What is a many-to-many relationship?</h3>
A many-to-many relationship is known to be one that exist if one or more items that is found in one table can have an association to one or more items in another given table.
Hence, A many-to-many relationship between classes A and B (where the maximum multiplicity on both sides of the association is *) is implemented by posting foreign keys in both A and B is a false statement.
