Your statement is incorrect. I explained the use of bidimensionality
to state that the physical representation of a relvar (in current SQL
implementation) is necessarily bidimensional at run time. Tell me
where I have declared that it's bidimensional a logical level?

It is not a claim it's a fact. 64 bit RAM architectures use an
adressing scheme identifying adresses through 3 coordinates
BlockAddress/ColumnAddress/RowAddress. Which makes your *recalling*
essentially irrelevant.

Speaking about computational model is irrelevant. Your comment made me
however understand where the misunderstanding comes from. You are
ignoring the relative nature of hexadecimal adress retrieval. Most
addresses are computed and are a result of a absolute direct
extraction. Current RAM use 2 or 3 coordinates to identify faster
addresses on relatively to the other. The adressing scheme is
referential for computing that has been existing since VSAM. If you
suppose Linear means monodimensional and that adresses are extracted
directly, you are wrong.

Wont comment on the rest no need.

Do you understand better now?
// J M Davitt asked once for clarification indicating you were not
communicating well and once pointed out that your style of quoting
interferes with communication. I don't recall him expressing any
confidence in his comprehension of what you wrote.//
Here's to refresh your selective memory.
JMDavitt first asked a question to warn me I was not communicating
clearly enough but he adressed directly the issue I was getting at.
//Clarification please: are you saying that direct image
implementations
I responded commenting onto adjacency and asking new questions to try
are two dimensional because all the columns are adjacent to each other
in a row? (If so, you're writing a very different language than the
readers of your posts are reading.) //
//Not only and the fact that they are adjacent is not really the issue
but this description seems closer to what I mean. Thank you very much
for helping a better formulation of the issue. (I may have troubles
expressing the concept). This thread seems to be taking off after all.
What is your insight on that.? Can OO in-memory mechanisms be helpful
on that matter? Most people here seem to believe the opposite. //
JMDavitt did not explicitely express that he had a comprehension of
issues at hand he just aked the right question about a subject with
delimited scope which makes the triggering argument having sense. This
is why I told you at several occasions that you miss the point (in all
respect).
// I long ago added Alvin to my twit-filter. I forget whether that was
due
to a lack of intellectual honesty on his part or worse. That he might
pretend to make sense of what you wrote does not make it any more
sensible.//
I do not know any people accustomed to this board and I do not have any
preconceived idea about what they are or say. I just try to exchange
with sincerity and respect. Alvin or you are no exceptions. I conceive
that disagreeing with them on a specific matter as being an potential
opportunity to learn something. This process may not be as practical
as puting people on twit filter when they disagree with me but it is
rewarding. My guess is I will probably be next on your twit filter
and your next thread reference as being intellectualy dishonnest.
// You have not established that anyone really made sense of what you wrote. One person tried to rephrase what you wrote into something he considered sensible, and he asked you for clarification at that time. The other person is just a fool. Fools talk nonsense all the time.// You are trying to establish nonsense on false assumptions and if necessary you disqualify as *foolish* or *nonsensical* anything that does not fit your perception of right and wrong.
*Fool*, *twit filter*, *nonsense* *lack of intellectual honnesty* --> Is that your witchhunt arsenal to defend your positions when people disagree with you and when you can not prove they are wrong. This attitude is scary and I do mean that in a friendly manner.
// Nothing is really relevant to nonsense. I am trying to give you an opportunity to rephrase what you are trying to communicate into something sensible. You keep refusing and insisting that your prior gibberish should make sense to people. Clearly, it does not.// Sorry about that but I can not give more clarifications than I already did to prove my good faith.
// I disagree. Confusing a property of a physical address space with a
property of a logical entity is nonsense. When I put a potato into
boiling water, I don't conclude that the boiling point of potatos is
100
degrees celsius nor do I conclude it is a property of cooked potatos
as
opposed to potatos in general.//
I am not confusing anything you are. So you use potatoes as an analogy
to explain bidimensionality of a relvar. It is totally irrelevant as
were your previous comment.
// Yet, having put a logical structure into a linear memory, you
expressed
a property of the linear memory as a property of the logical
structure.
Don't do that. It's nonsense even if you say it only applies to the
implementation of the logical structure in the physical address
space.//
No that would be totally silly. These are conclusions you are making
I stated that the SQL *physical* implementation on *current* DBMS
systems in necessarily bidimensional at run time because of the
addressing scheme used is a limiting factor to better representation
BUT I have never stated anywhere that a relvar is bidimensional. The
latest part of the sentence is your interpretation. I suspect you
either misunderstood or you are making a confusion between a relvar and
its possible in memory representation.
you to discover or look up the correct english word for what you are trying to communicate, making up gibberish wastes time while defeating
your purpose.// That's your opinion. I will keep it in mind.
