Joe, DRDA competes against ODBC, as to the differences, I am not familiar enough with ODBC to say. DRDA is used mostly by IBM for database connectivity between multiple computer systems in a network and uses SNA and CPIC (Systems Network Architecture / Communications Program Interface Side Information). "DRDA is a set of protocols that coordinates communications between the systems. DRDA describes two levels of architecture: remote unit of work and distributed unit of work. All DRDA products support remote unit of work. With remote unit of work, you can access one remote relational database manager with multiple requests within one unit of work." Ref: Distributed Relational Database Architecture Connectivity Guide SC26-4783-02 It is my understanding that ODBC ..Object Data Base Connectivity does pretty much the same thing but uses different protocols to accomplish the task. One thing that I am certain about, is that to use products such as Data Hub and Data Propagator Relational, you must use DRDA, of course since IBM is writing much of their software for Windows systems, this may have changed? Hope this helps, Howard ---------- From: Joe Teff[SMTP:jteff19@idt.net] Sent: Tuesday, February 24, 1998 8:44 PM To: Midrange dot Com Subject: What is DRDA? I have come across the term DRDA (Distributed Relational Database Architecture) several times and I'm not sure what it really is? Can someone explain this in English? What does it compete against and how does it differ from these things? Thanks.
