    1. the interesting thing about this paper is that it
    was actually written almost 10 yrs ago.
    so we are given the gift of hindsight in evaluating
    the author's opinions.

    2. they focus on 4 major approaches on incorporating
    OOP and relational approaches to data management

    3. today, ADTs in rdbms appear in OO-databases
                    persistance in programming languages appear
    less pervasive
              db toolkits do not appear used at all,
    essentially same conclusion in '96

    4. with the advent of XML, the OO aspect of data
    management has also been abstracted such that
    old-school relational methods could still be used -
    still and active area of research

    5. language-specific rdbms wrappers are still very
    impt
       object-relational dbms' are still not totally used,
    even if the ideas appeared most favorable in '96
       pure-relational or obj-rel approaches are still de
    facto standard in the industry, even with the growth
    of internet

    6. why is it so hard to change? SQL is a pervasive
    STANDARD. standards are notoriously hard to enforce.
       XML adoption today may be important as it is a
    standard that most parties are trying to adhere to.

    7. authors were partly right about obj-rel db's
    becoming more impt in 10 yrs
       and yes, oodb's haven't caught on in a big way,
    though they might exist - performance issues
       not sure if parallelization has been used to
    optimize current existing rdbms'

    in all, the authors were mostly right then, a few
    years after the internet became the WWW to most
    people.
    it seems the ease of programming in most cases fell by
    the way side when performance and adoption issues
    came to fore. both of these aspects have a huge
    influence on cost. at some point however, I imagine if
    XML become as important as SQL, then a new db model
    may evolve more by necessity than by choice
