Question

A Distributed Database Management System (DDBMS) manages the database as if it were all stored on the same computer. The DDBMS synchronizes all the data periodically and, in cases where multiple users must access the same data, ensures that updates and deletes performed on the data at one location will be automatically reflected in the data stored elsewhere. Based on this information, compare and contrast the advantages and disadvantages of having a DDBMS versus a centralized database structure. When is one type of DBMS structure preferred over the other? Please provide two to three real-world examples to support your arguments.
