In remote data management, the entire application resides 
on the client and the data managment is located on a remote 
server/host.   Remote Data Management is relatively easily 
to program for because there is just one application 
program. The client communicates with the server using SQL, 
the server then responds with data that satisfies the 
query.  RDBMS products that offer remote data management 
provide a layer of software on the client to handle the 
communication with the DBMS server.This style represents a 
more traditional LAN database server or file server 
approach. 
Workstations support the presentation and function logic 
and interface with the data server through the data 
manipulation language.Distributed data management is an 
extension of remote data management and uses the 
distributed facilities of the DBMS to access distributed 
data in a manner transparent to users. This is most 
relevant for architectures having data spread  across  
several servers and when access to a DBMS on another 
server is required.
