It is known that the customer tables are initially stored on a centralized database server. To increase efficiency in access and operational costs, the database was made distributed in several branch areas. An example of a customer table looks like this:   a. There are several types of fragmentation, explain! What type do you use if you do fragmentation of the table above? Explain how the fragmentation is done and give reasons why choosing this type! b. Describe how the fragmented table will look like and describe it according to 3 rules (completeness, reconstruction, disjointness).
