11.
A distributed database management system (DDBMS) governs the storage and processing of logically related data over interconnected computer systems.
12.
Distributed data access was needed to support geographically dispersed business units.
13.
Rapid ad hoc data became unnecessary in the quick-response decision-making environment.
14.
The Internet is the repository for distributed data.
15.
Current distributed database management system (DDBMS) are subject to some problems, such as the complexity of management and control
16.
Distributed processing shares a database's logical processing among two or more physically independent sites that are connected through a network.
17.
One of the advantages of a distributed database management system (DDBMS) is that the data is located near the site with the least demand.
18.
One of the advantages of a distributed database management system (DDBMS) is growth facilitation.
19.
One of the advantages of a distributed database management system (DDBMS) is security.
20.
Distributed processing does not require a distributed database, and a distributed database does not require distributed processing.
21.
In order to manage distributed data, copies or parts of the database processing functions must be distributed to all data storage sites.
22.
A database management system (DBMS) must have validation, transformation, and mapping functions, as well as other functions, in order to be classified as distributed.
23.
A fully distributed database management system (DBMS) must perform all the functions of a centralized DBMS, and it must handle all necessary functions imposed by the distribution of data and processing.
24.
The transaction processor (TP) is the software component found in each computer that requests data.
25.
A distributed database management system (DDBMS) must be communications-media-dependent.
