At least 10 key/value pairs in different combinations in your databaseyou are expected to add.). Then, by reading from the same database, the key / value pairsensure that it is written with original and user-understandable values ("unpickling"those that require it will need to be separated from those that do not).

Task 1: The InstantRide Management team founded a new team for car maintenance. The new team is responsible for the small maintenance operations for the cars in the InstantRide system.
