Centralized DBMS:
- In centralized DBMS data are located
at single server
|
- Centralized DBMS is used in
small organization.
|
- Centralized data is simple
& successfully done by a single person.
|
- Company operations & the
scope of the problem are stored by single person
Decentralized DBMS:
|
- In decentralized DBMS data
located at different serves.
|
- Decentralized DBMS is used in
large organization
|
- In large & complex projects
the data base designed the typically can’t be done by only 1 person.
|
- In that case a selected team of
data base is employed to tackle a
complex data base project.
|
- In the decentralized DBMS the
designed frame work the data base designed task is divided in to several
modules.
|
- Each designed group creates an
conceptual data model corresponding to the subset being modeled.
|
- Each conceptual model is then
rectified individual and after verification process has been completed
all the modules are integrated in to one conceptual model.
