Discussion 2 – Unit 6

COLLAPSE

Distributed Database

Management Systems

A distributed database management system (DDBMS) stores a logically related database over two or more physically distinct locations connected by a computer network. A DDBMS must perform all the operations that a usual DBMS must perform and additionally manage the distributed data that is stored in the multiple sites of the DDBMS. A DDBMS presents both advantages and disadvantages over a standard DBMS.

To prepare for this Discussion, read the following:

• From the text, Coronel, C. & Morris, S. (2015). Database systems: Design, implementation, and management (11th ed.). Stamford, CT: Cengage Learning, Chapter 12, “Distributed Database Management Systems”

Now, discuss the following points:

• In which type of application or situation would you consider using a distributed database instead of a centralized DBMS?
• When would you want to use a centralized database instead of a distributed database?
