Which generation of OOT Now?
Sonny Seo
While researching migration strategy with OOT,
I found some doubtness by myself.
According to the book 'Migrating to Object Technology' (Graham 1994:32),
he mentioed that we are already on the stable and reliable stage
with OOT against the hype that usually appears when new technology is
coming.
But, I found there are still lots of companies where they consider
themselves as early adaptors of OOT with big struggle. Of course, lots of
the other
companies are very happy with OOT.
Here, I've got two serious questions.
1) Which generation of OOT we are belong to at the moment.
(could you someone propose how to distingush each generation?)
2) Is there any survey, report or research on statistics of using OOT on
the Web?
Many thank you for your help.

Hi,
I have not gone through the book "Migrating to Object Technology" by Graham.
I am also not sure as what he is meaning when he says that OOT has already
reached a matured stage. You have to be watchful as the book has been written
during 1994. Lot of things have changed since then.
However, I can answer some of your questions ...

Currently according to the methodologist we belong to the "Third
Generation of Object Methodologies". The classification is done in the
following way ..
First Generation - All methods which have been proposed
individually like Raumbaugh, Jacobson, Booch, CRC, Formal methods,
Shaler-Mellor, Yourdon-Coad etc. These ideas were original and have been
written based on their experiences and their success with that method.
Second Generation - These are the methodologies which was formulated
based on the collection of good techniques present in the First Generation
method. Basically it is a collection of good techniques with a particular
sequence. Example of this is FUSION which used the good techniques from
Raumbaugh, Booch, Jacobson, Formal methods
Third Generation - These are the methodolgies which are formulated to
arrive at a consensus in the modelling approach and notations. Basically, it
was started to arrive at a universal standard in Object Modelling. Example of
this is UML which is the unification of notations of Raumbaugh, Booch,
Jacobson with other partners like Microsoft, Oracle, HP etc. The other example
is OML which is the unification of behavioural object modellers like Brian
Henderson-Sellers and others under OPEN group.
So still we have 2 methodologies and hence one can expect the Fourth
Generation very soon :-)

I have not seen any survey. But www.sigs.com should contain somekind of
reference to this. Please let me know if you find any as I am also interested
in knowing this.
Hope this helps,
