059. How can data be distributed?

 

There are two common methods for distributing data:

 

1.      Replicated databases. In this approach, data is gathered at some point in time and merged together by some central location, and then distributed to all (or some) of the remote sites. 

2.      Partitioned databases. In this approach, only the data that is most typically used at any remote site is given to that site. If they require additional data, they can communicate with one of the other remote sites.
