656.0. "IMS II DBMS on a Burroughs B1XXX"" by DELREY::LANGSTON_BR () Wed May 23 1990 02:17

    I'm looking at an RFP.  The requestors have an existing Burroughs B1000
    with IMS II Database Management System.  Later, they refer to the
    computer as a B1985.
    
    The proposal states that "a comparable Data Base Management System must
    be proposed" for consideration.
    
    What is IMS II?  Is it network (CODASYL) or relational or something
    else?  Which of our offerings is "comparable"?  Probably none.  This
    system is almost none years old.
    
    I feel like a "solution" that provides them what they need will
    probably make more sense than a DBMS that is "comparable."
    
    I've just about finished a similar proposal with a third party
    (Information Associates) providing the Student Information Systems
    applications packages for a community college district.  Maybe they'll
    consider something like that.

	Check to make sure that the "D" key on the customer's typewriter is functioning properly. I worked for Burroughs for 6 years supporting DMS-II (Database Management System - II), and unless they've re- marketed the product as IMS-II, we're talking about the same thing. [Rationale for this: It hasn't been all that long since I left - I doubt they've reengineered the product to "I"MS. The "II" implies "second version", and again, it hasn't been all that long. Also, IMS, I would imagine, is a trademark.] Be that as it may, "D"MS-II is primarily an inverted list database system that can be implemented in a network, hierarchical, or list fashion. To my knowledge, they are not relational in any way, shape, or form from the DMS-II standpoint. Burroughs does have a product called LINC (Logic and Information Network Compiler) that relies on relational design principles and presents a relational view of the database, but the underlying DMS-II is still non-relational. It is a well-received and mature database system, with a high degree of user satisfaction and loyalty. Unless the user wants relational. For more specific information, I might suggest looking up the Datapro writeups on DMS-II... that's probably your best source of technicalities. Here in the NY/NJ Area, we've recently signed up a long-time customer of mine from the Burroughs days as a new OEM. They will be undergoing a conversion of DMS-II to Rdb (I think I'll regret making this known to the noting public ;^) ) facilitated by ISI (Mass.) and Digital's ACES/PS group. As far as the B1985 system... It's an older system (circa 1984-85) with 1-2MB memory. Warning: Apples to Oranges here. Memory utilization of MCP vs. VMS is radically different, since the 1985 uses a very efficient stack architecture. Terminals, for all intents and purposes, are blockmode poll/select. Disk utilization is different also, so it's difficult to make spec comparisons. If I were to suggest a "similar" DEC platform, it would be in the 3400 range, but I would check this out quite carefully with groups who keep tabs on these things. Let me know if I can be of any help. Bob
