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.
