 ## Explanation

 Real world example
 
-> We have a database containing student information. Administrators all over the country are constantly updating this information and it causes high load on the database server. To make the load more manageable we apply to Unit of Work pattern to send many small updates in batches.

 In plain words
 
-> Unit of Work merges many small database updates in single batch to optimize the number of round-trips.
