3.1 ADDE - Clients and Servers
ADDE distributes data using networked servers and clients. Servers store
data and distribute it to the client. Clients request and receive data
and run applications that use the data. Clients and servers communicate
using the TCP/IP communications protocol.
Each account running McIDAS-X acts as both
a client and local server. When a client requests data from the
local server, it searches for the data in the
directories specified in the user's MCPATH
environment variable or another directory specified in a
The client can also request data from a remote server. A remote server
can be any of the following:
The difference between a local server and a remote server on a McIDAS-X
workstation is that the data stored in a local server is available only
to the McIDAS-X sessions started under that account name. Data in a
remote server is accessible to all McIDAS ADDE clients.
Remote servers are discussed more thoroughly in the Site Administration
and Management section of the ADDE portion of the
Unidata McIDAS User's Guide.

a remote server
