CitectSCADA uses the following methods
to exchange data:
dynamic data
exchange (DDE)A Microsoft Windows standard protocol set of
messages and guidelines that enables communication between Windows

DDE client
to request data from other applications.
open database
connectivity (ODBC)Allows applications to access data in database
management systems using structured query language (SQL) to access
data., where CitectSCADA functions as an ODBC
